Boiler SZL8-A2(Coal burning boiler)
SZL series "A" type chain grate boiler
Our company SZL type boiler is a double-drum water tube assembly chain grate boiler . The boiler proper has an upper drum and a bottom drum longitudinally arranged along the boiler center. The front of the upper drum and two sides water wall tubes constitute the boiler hearth radiation heating surface, and the tubes between the rear of the upper drum and the bottom drum constitute the convection heating surface. 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.
