Instruction
DZH Coking coal Boiler adopts high efficient heat transfer components - threaded pipe, with a reasonable flue flow rate, boiler efficiency is higher than the national professional standards 6~8%; the convex tube plate and threaded pipe make the boiler drum from quasi-rigid body to quasi-elastic body, which be with airfoil style flue completely avoid the drawbacks of traditional fire tube boiler high temperature tube plate cracking. The boiler dust inertia separation combined with efficient water film dust collector make the ash to meet the requirements of Class A.
The series coking boiler can reach the environmental effects of the gas boiler by burning bituminous coal cost , environmental protection and energy saving.
