Gas heaters


Howden supplied some of the world’s first FGD systems in 1934, and since then we have become a leading supplier of gas gas heaters.

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.
