DZL series coal biomass fired boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. This furnace structure 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.
