Coal Fired Steam Boiler DZL-Series boiler is horizontal single-drum shell boiler with water-fire tubes. It has chain grate as burning device, upper-in-and-upper-out style natural water circulation with ejection for hot water boiler of this series, the right and left side of furnace as radiant heating surface, two wings of furnace and threaded smoke tubes as convection heating surface and three-dimensional shield shell. Furnace is divided by Smoke baffle wall into combustion chamber (firebox) at front and reburning chamber at back.

Chain Grate Stoker Coal Boiler, Coal Fired Boiler Burning process

Fuel falls from coal hopper onto the front of chain grate, moves along with the chain grate and will be preheated, dried, ignited, burned out. Slag will be discharged by slag remover(eliminator) at any time. Herring bone arch is adopted to improve igniting condition. Smoke forms between front and back arches vortex, completely mix with air, burns out and then goes after each other through smoke flue at two wings, front smoke box, threaded smoke tubes, cast iron economizer(for hot water boiler no cast iron economizer), dust remover, draft fan and will be emitted through chimney.
