Through a process of continued development and product enhancements, the renowned three-in-one COSPECT pressure reducing valve from steam system specialist TLV Euro Engineering has been upgraded and is now being offered with integrated pressure gauges as standard across the range.

Commenting for TLV Euro Engineering, general manager Michael Povey says: “By upgrading and offering the pressure gauges as standard across the range, we have enhanced the COSPECT to make it even more of a unified steam system solution. The integrated gauges also mean no additional pipework modification is required before or after the PRV, which reduces installation time and minimises process downtime.”.

Originally launched over 35 years ago, the COSPECT is a combined pilot-operated pressure reducing valve (PRV), cyclone separator, strainer and steam trap in a single component that overcomes the limitations and inadequacies of conventional PRVs and solves their many associated problems – including fluctuations in primary and secondary pressures and valve hunting and vibration – to provide improved-quality dry steam at a constant pressure and temperature.

By eliminating the conventional arrangement and combining four separate components into a single valve, the COSPECT delivers numerous engineering benefits by incorporating fewer gaskets, spool pieces and fixings, improving moisture separation and providing accurate and stable pressure control. It is also more sensitive to downstream pressure fluctuations, is reliable in operation and its unified, modular construction facilitates easy, in-line maintenance.

In addition to the engineering benefits, the single component design of the five-model COSPECT makes it faster and easier to install, is lighter than the sum of using separate components, reduces the amount of insulation required and reduces the requirement for pipe support brackets, etc.

In 2015, with business improving but original process equipment reaching end-of-life, Rebellion Beer Company bucked the trend and, with impartial advice from heat transfer specialist Fulton, replaced its ageing steam boiler for a thermal fluid system. Now, six years on, we approached Rebellion’s Mark Gloyens to update us on how brewery life has coped with the switch.

Anyone running a brewery will tell you just how critical the boil phase of the brewing process is; and when Rebellion set out on its journey from steam to thermal, they were warned that they’d never succeed in getting that clean flavour achieved from a steam-driven rolling boil.

“The move from steam to thermal was a leap of faith on our part, but the warnings received from other breweries have been proven to be incorrect!” says Rebellion Beer Company’s Mark Gloyens. “Product quality has improved because we now have more control over temperature for the wort boiling process than ever before. We’re getting a very good quality boil that is controllable and we have achieved everything we wanted from the move from steam to thermal fluid”.

Thanks to the control and flexibility that the thermal system affords Rebellion, the brewery has had the ability to achieve various size batches as and when required. Until recently, this has enabled them to process research and development batches and has been especially useful throughout the pandemic when, at the beginning, throughput was decimated because pubs were forced to close. However, as lockdowns came and went, Rebellion successfully pivoted its business and started selling direct to the consumer via a home delivery service, which meant throughput very quickly returned to pre-pandemic levels, currently two to three batches per day, with each boil lasting up to 90 minutes.

“The beauty of the thermal fluid installation is its flexibility and ability to very easily adapt our changing brewing strategies.” says Mark. “Historically we would have been doing two brews per day to achieve maximum output, but because of its flexibility, we are now able to shut the thermal fluid heater down for a day per week to deep clean the brewhouse and increase output to three brews per day for the remainder of the week. Something that would have been very difficult to achieve with steam.”

Beyond the control and flexibility, there are many other factors that have had a positive impact on Rebellion Beer Company, as Mark explains: “A steam boiler is essentially a pressure vessel and regulations state that pressurised systems must undergo an annual insurance inspection. This inspection would often take the steam boiler offline and mean our brewing processes were down for a day or more, with disruption from the downtime potentially being felt for several days after. Additionally, with even the best water treatment programme in place, steam at pressure can be very corrosive, leading to problems with steam traps, flanges and pipework, which we always seemed to be maintaining and was always therefore another potential for process downtime. 

“With thermal being more of a closed loop system, we’ve not experienced the same issues with leaking gaskets, flanges, etc., making the whole installation not only look but also feel so much more reliable than steam!”.

In putting a figure on the annual cost savings of maintaining a steam system – including servicing, water treatment, chemical dosing, etc. – compared to thermal fluid, Mark Gloyens estimates that the thermal fluid system is much lower and could be at least half that of the previous steam boiler installation. And six years on, Mark estimates that the savings made compared to maintaining the old steam system – and despite the thermal fluid installation being a more expensive capital outlay initially – has certainly contributed significantly to the return on investment, with the investment now fully paid for.

Expanding on the flexibilities of the thermal fluid system, Mark has also announced that Rebellion is about to tap into the existing brewhouse line to create a small-batch development brewery and yeast propagation plant on the site. “It’s been such an easy expansion to achieve. We’ve just been able to tap into the existing thermal fluid line and use the system for another duty without impacting on everything else.” says Mark.

The new development line is capable of brewing five hectolitre (500 litre) batches and will enable development or commercial batches – such as strong beers or one-off batches that may not appeal to the wider consumer – to be processed without having to invest in a full 4,000 litre brew.

Summarising, Mark Gloyens says that whenever he’s asked if Rebellion is happy with the thermal fluid installation from Fulton, he simply tells them to come and take a look because it speaks for itself. “It’s just a neat, compact installation that’s relatively maintenance free and extremely flexible!”.

And when asked about his advice to anyone considering a new brewhouse or complete overhaul of existing plant; and perhaps sitting on the fence when it comes to considering steam versus thermal? “You obviously need to consult the experts as we did when we approached Fulton over six years ago. They were completely unbiased because they manufacture both steam and thermal fluid solutions.”. says Mark. “But for Rebellion Beer Company, a thermal fluid solution was a no brainer. It’s more cost-effective, more reliable, relatively maintenance free and a much neater, more compact system that still provides the quality of heating needed for brewing. It’s just a better way of doing it!”

With a requirement for new steam boilers with increased capacity, higher efficiency and more eco-friendly emissions when expanding their operations at a second facility in Romania, Universal Alloy Corporation had no hesitation in turning to heat transfer specialist Fulton, the supplier of steam boiler solutions already installed at its facilities in Romania and Vietnam.

Heat transfer specialist Fulton has supplied, assisted with installation and commissioned two gas-fired, horizontal RBC3000 steam boilers for Romania-based Universal Alloy Corporation (UAC), a manufacturer and fabricator of high-strength, hard alloy extrusions for aircraft structures or where precision-engineered products are critical. This is UAC’s second Fulton installation in Romania – at an all-new facility built to cope with increased demand from the airline industry – and third installation across its sites in Europe and Vietnam.

In accordance with strict Romanian regulations on the installation of new plant equipment, including steam boilers, as the OEM Fulton had to be in attendance at the system testing stage, ensuring reliable, maintainable steam could be provided ahead of a planned visit by several prestigious UAC customers. This meant that Fulton’s engineering services supplied support from the UK and, in line with current COVID-19 guidelines, had to self-isolate for two weeks following the test-fire visit.

Under normal operating conditions, the two RBC steam boilers at the new Romanian facility are setup for N+1, with steam being used to heat water in several large vessels via coils, with the water being used for quenching purposes during component processing. Steam is also being passed through coils for a heater-dryer system at the end of the same processing line.

For the steam boilers supplied to UAC, Fulton partnered with renowned burner manufacturer Weishaupt and supplied the RBCs with two low-NOx, fully-modulating burners and reconfigured the boiler steam outlet nozzles to run at just 2 bar. The use of a Siemens high integrity digital burner management sytsem means the boilers are capable of achieving at least 7:1 turndown, something not always achievable from large horizontal firetube boilers.

Additionally, unlike typical gas pressures in the UK of approximately 20 mbar or 60 mbar on the continent, the supply at UAC’s site in Romania was 1.6 bar, so Fulton and Weishaupt provided an over-protection rig for the gas components in the gas train. While the gas supply to the gas train is now regulated to 95 millibar, the over-protection rig ensures that a slam-shut system is enabled should the gas pressure exceeds 180 millibar, completely negating any possible component damage.

In addition to November’s test-firing visit, two of Fulton’s engineers visited Romania in September to service the RBC boiler at UAC’s original facility and commission the two boilers at the new plant. Again, both engineers followed COVID-19 guidelines on self-isolating when returning to the UK.

Both visits also provided an opportunity for the training of key boiler operators at UAC’s new manufacturing facility which, as well as the usual instruction and guidance, also ensured that operators were educated on the start-up procedures in both low fire hold and auto modulation modes for these particular boilers 

Offering higher capacities than the 2500 kg/h maximum for its VSRT range of vertical boilers, with outputs to 4787 kg/h and a maximum working pressure of 10.34 bar, Fulton’s RBC range can be specified with matched multi-stage oil, modulating gas or dual-fuel burners as standard, with other burners available on request. The boilers are constructed to BS12953 standard, meet current and anticipated legislation and have been engineered to provide a substantial performance margin.

In this article, Fulton’s aftercare and business development manager Jeff Byrne takes a look at technical boiler house risk assessments, from their legalities to the potential savings that can be achieved.

It is strongly advised that all companies with a steam boiler have a technical risk assessment in place for its boilers and boiler house. It is required by law under the Management of Health & Safety at Work Regulations 1999 and is necessary to comply with the requirements of SAFed document BG01, HSE INDG 436 and HSE INDG 417 Rev1, under which steam or hot water plant should be operated.

Why do you need a Technical Boiler House Risk Assessment?

Besides the legal requirement, a faulty steam boiler brings with it the risk of a steam explosion. With significant stored energy, failure of steam (or pressurised hot water boiler plant) can produce a similar level of destruction and/or devastation as a bomb, potentially causing catastrophic damage, serious injury and possibly multiple fatalities. With around 100 pressure vessel failures and at least one fatality per annum in the UK (HSE RIDDOR 2014), the importance of a technical boiler house risk assessment (TBHRA) cannot be overstated.

So, a TBHRA is therefore essential for owners, operators and managers to ensure that staff are aware of the risks and their responsibilities for the safe operation and management of industrial steam and hot water boiler plant. It is also likely to be the first thing a HSE inspector would ask to see in the event of an inspection.

A TBHRA is also a vital link in the safety chain to identify risk and develop measures to mitigate those risks, thus ensuring the safety of all involved with the plant.

We simply cannot stress the importance of the TBHRA enough, because non-compliance with the law can result in substantial fines and the likelihood of a custodial sentence in the event of serious injury or a fatality.

The Fulton approach to TBHRAs

Fulton’s method with the TBHRA requirement is to take a very collaborative approach with its clients; and use only experienced steam boiler and steam system engineers with over 60 years’ knowledge of not just steam boilers, but steam, water and condensate systems. 

This highly-experienced team will scrutinise and photograph every area of risk and will produce a full report proposing and prioritising mitigation measures. This will give owners, operators and managers peace of mind that their plant may be operated safely and that all relevant guidance and legislation is supported once any identified hazards are rectified.

What are the typical findings of a TBHRA?

Unlike a vehicle MOT, a TBHRA does not pass or fail a steam system, but instead highlights hazards and the potential risk and then proposes measures to rectify any issues. 

According to INDG 436 “a risk assessment does not need to include excessive detail”, but issues highlighted can include boiler specification, location, operation and condition, poor record keeping, lack of suitable/relevant training or trained operator absence cover, shortage of plant drawings and manuals, control system reliability, ventilation issues, poor/no suitable operational procedures, water quality issues, etc. 

Beyond the TBHRA?

Once its assessment is completed and delivered, there is no commitment by the customer to involve Fulton in any post-assessment remedial works. But the document does highlight areas of the steam system that require attention and will prioritise the risk they pose from high priority (red) to lower priority (green). The assessment must also be made available to the boiler operator and, in the event of the sale of equipment, the new owner/operator.

However, unlike a MOT, a TBHRA is a live document that should be updated on an ongoing basis when any changes or modifications affecting the operation of a boiler occurs. This can include personnel changes, additional training, physical changes including boiler/burner upgrades, legislation amendments, etc.

Fulton can offer support to the customer once the TBHRA has been completed, or during or after the annual review. This support can be provided onsite or via telephone or video conference assistance once the review is completed.

A TBHRA also offers excellent value for money because it not only highlights areas of potential risk for owners, operators and managers, but can also identify where enhancements to the steam system could lead to improved energy efficiency. For example, the cost to replace an old, inefficient or dangerous burner could easily be offset within a few years by the fuel savings achieved through the upgrade.

In a move that will present fewer Brexit-related issues for its customers, increase its stock holding and strengthen ties with its parent company in Japan, steam solutions specialist TLV Euro Engineering has expanded its UK operations with the opening of a new 6,000 square feet warehousing facility in Cheltenham.

Commenting for TLV Euro Engineering, general manager Michael Povey says: “As we neared the end of 2020 it became clear that, whatever the outcome of a trade agreement between the UK and European Union, our customers would benefit more from the trade agreement reached between the UK and Japan.

“Until recently, we had partnered with our sister company in Germany but knew very early on that any trade agreement with the EU was going to present issues. However, we weren’t willing for these issues to lead to increased prices for our customers so, as 31st December 2020 approached and we learned more about the proposed import/export processes our plant in Germany would have to implement, we put our post-Brexit plan into action and forged ahead with plans to import stock directly from Japan.”

TLV Euro Engineering has now formally entered into trading partnership with its parent company and manufacturing facility in Japan, a move that will see the company increase its stock holding of steam system solutions in the UK from £150,000 to £800,000 worth of stock.

The investment in its UK operations and near 450% increase in stock meant the company had to worked tirelessly throughout the recent Christmas shutdown to ensure its new facility – which offers a six-fold increase in capacity on its previous warehouse – was fully stocked, operational and despatching orders by the start of business in the New Year. 

The new facility, which is located at Furlong Business Park in Bishops Cleeve, Cheltenham, is now fully-operational and holds over 1,000 steam system parts available ex-stock and, in many cases, for next-day delivery.
