Manual Coal Fired Steam Boiler Grate

Product description

Manual coal fired steam boiler grate adopts a three-return water-fired tube structure with a single drum longitudinally arranged. The two sides of the furnace are densely distributed with light-tube water-cooled wall tubes. The design structure is reasonable and compact; the heating area is large, the flue gas flow is long, and the heat transfer effect is good. The smoke temperature is low, so the thermal efficiency is high, the operating cost is low, and the use is more economical.
