Our company SZL type boiler is a double-drum water tube assembly chain grate boiler (A type layout). 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 econom-

izer 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.

Core technology:

1. Longitudinally arranged double drum 

2. Airtight and uniform-pressure wind room

3. Customized combustion device

4. "α" type flame combustion

5. High quality aluminum silicate insulation

6. Built-in dust cleaning

7. Easy operation control system
