• Furnace construction utilizes a welded-membrane wall design.
     • Convective and interstage superheaters.
     • Large, water-cooled, gas-tight furnace areas.
     • Boiler wall constructions are 100% water-cooled and refractory-free.
     • Only single-source supplier for integrated boiler, burner, and control solutions.
     • Radiant superheater designs are available.
     • Can accommodate selective catalytic reduction (SCR) and CO catalyst.

        The D-type is a 100% membrane water-cooled furnace, reducing costly, time-consuming, annual maintenance. The front and rear walls are welded and refractory-free, as well as the burner throat, when integrated with our Natcom® burner. D-type boilers can be customized to provide superheated steam. We offer both single- and dual-stage integral superheater systems with optional temperature control over turndown.
