The Howden VN design concept is ideally suited to the FGD Gas Gas Heater application. Judicious selection of materials, together with advanced design features result in a heat exchanger with exceptional resistance to the cool, moist acidic conditions of FGD plant, where fouling and corrosion are a constant challenge.
Gas gas heaters can be custom designed and optimised to suit arrangement and client preference. If the GGH is being mounted directly on top of the FGD Absorber, construction of the GGH at ground level and a single lift can reduce costs. We are also able to install a tail end SCR gas preheater if this is required due to the specific set up of you power station - you can read more about this in our brochure.
The first company to form a joint venture with Fredrik Ljungström, we have been designing and improving rotary heat exchanger technology ever since.
Continual research, development and analysis of both new and aftermarket heaters to optimise product performance and reliability.
We are accredited to ISO 9001, ISO 14001 and OHSAS 18001 and are regularly audited by major customers and internationally recognised assessment organisations.
In our experience, there is no substitute for local support; that’s why we have local teams ready to help.

The introduction of Howden’s VN seal system to the air preheaters brought an immediate drop in leakage level from 26% to 5%.
At Howden, we have developed a range of element profiles, materials and coatings designed to offer optimum longevity and cleanability in every situation.
Replacement of primary plate heaters with Howden custom designed rotary air preheaters, greatly improving thermal performance.
When Tucson Electric Power (TEP) Springerville Station was experiencing major air leakage issues, they called on Howden to rectify the situation.
The leading manufacturer of heating elements irrespective of the original manufacturer.
It’s our duty to offer only the very highest standards of service whatever their needs, from initial installation of plant and equipment through routine maintenance to subsequent refurbishment and enhancements.
Over the many years of our ongoing heater applications experience, Howden have investigated and developed important innovative solutions including leakage sealing systems, cleaning systems and intelligent monitoring.
