Product Description


Hot Sale! Wood Chip Fired Water-Fire Tube Steam Boiler


DZL series coal fired boiler is single drum water-fire tube boiler, chain grate type. Water wall tubes at left and right sides of furnace are the radiated heating area. it has two wings at furnace and screw fire tube in the drum are convection heating area. The upper drum, water wall tube and its heads are in symmetrical arrangement mode. This why furnace structure is in reasonable arrangement and high efficiency. This series boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.This boiler uses the new scientific achievement, such as arch tube plate and corrugated tube, to solve the problem of tube plate flaw and water wall tube explosion, improve the heat transfer efficiency and thermal efficiency, increase the output. The boiler is wide adoptability of different fuels, such as coal, biomass fuel, wood, straw, bagasse, rice husk, coconut shell, etc.
