D type watertube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam).
The D-style 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-style boilers can be customized to provide superheated steam.
OverviewIt is designated as a D-type boiler because of the relative positions of the drums and side header which form the letter D. All D-type boilers are designated as uncontrolled superheat boilers because all the steam generated by the boiler must pass through the superheater.
