Economisers for steam generators have been around for many years but few manufacturers offer
economisers for thermal fluid heating systems and even fewer still provide integral
economisers.
Neil English, managing director at ThermTech, which specialises in tailor-made
economisers, explains: "Every application is unique in some way, so it is very important to carefully assess the existing boiler system and then design the most suitable
economiser that can be easily retro-fitted.
The Greens company in Indiaexpects further development in the future built on the Group's substantial experience in supplying
economisers, waste heat boilers and HRSGs to all major markets and to many International boiler companies.
Fluegas
economisers are a proven concept and can improve boiler efficiency by up to 5%.
The latest heat transfer surface design of the Babcock Wanson
economisers permits dual fuel operation with both gas and light oil greatly extending periods between cleaning due to the non fouling finning of the extended heating surface.
Although there have been several fuel saving innovations incorporated into the boiler-house refurbishment, the main contribution comes from the new
economisers which are fitted within the existing boiler shell.
Wellman Robey, is able to offer a complete range of ECA compliant steam and hot water boilers, together with associated burners and
economisers. The company says it offers a free boiler house health check service, carried out by its own team of specialist boiler engineers who can identify areas where you can improve the efficiency of your boiler plant, and supply you with all the details you need to apply for your loan.
The scope of boiler house refurbishments is large, including covering pipe work upgrades, new boiler house control panels and new
economisers. Wellman Robey offer a wide range of services aimed at improving the efficiency and reliability of boiler houses.
With the company's range of
economisers and energy efficient boilers, Wellman Robey has shown at Maintec 2006 that there are vast fuel savings to be had with minimal expenditure.
Roderick Williams sales director said: "We have significantly raised the standards within the boiler rental market place, we will continue to invest in new boilers as we are committed to improving the levels of service and equipment to our ever expanding client base." Mark Hills managing director commented: "Not only are we investing in new boilers, but we are utilising the best and environmentally efficient technologies with Hamworthy Low Nox burners, we have started manufacturing our first ever hire units with
economisers to aid our client fuel efficiencies."
Speyburn's new Robey Loos 'universal steam' type boiler with integrated
economisers' (UL-SIE) is rated at 5000kg/hr and is designed to fire natural gas and diesel oil.
A For
economisers to work, the boiler needs to be gas-fired as oil can foul the finned tubes in the
economiser, restricting heat transfer.
