SZL boiler belong to double drums water tube boilers, designed for blowdown on surface and the quality of steam is pretty good.Steam boiler is devided into saturated steam boiler and overheat steam boiler and meet the needs in seperated.Boiler main body and grate adopt large parts for ex-factory, short installation time and low charge for installation.boiler capacity of 4-35T / H (2.8-29MW).The economizer is arranged on the rear of the boiler,part of heat from high temperature exhaust gas generated by burning was absorbed by economizer, then the exhaust gas go through the cooling chamber,exhaust gas enters the convection heating surface to transfer heat power again, and through economizer,dust collector, finally draught by ID fan to Chimney,discharges into the atmosphere.(Biomass Water Tube 15ton Steam Boiler for Plywood Factory)
