SHL series boiler is the bulk industrial boiler with dual boiler cylinders and transverse arranged, as well as the natural cycling coal combustion water pipe boiler. The transverse upper and lower boiler cylinders and water cooling pipe walls together form the silo type furnace, together with convection pipe bundle and collection chest to form the boiler body frame. A the rear part, there is a coal saver air pre-heater, and superheater can be set up in the furnace if necessary. The combustion equipment is squama grating, free timing control, exit shop in bulk type for site assembly and construction. The smog flow is a type of multi-backhaul.



1. The series boiler is capable of over duty. Temperature rises quickly, high thermal efficiency, occupy less area.
2. Leakage free squama grating makes greatly enhanced reliablity in performance, various kinds of coal are adaptable.
3. The furnace wall can be built in casting way, good sealing, the combustion condition is improved, environment protect and energy saving, combustion fierce.
4. High extent in automation, performance is stable and reliable, longer working life.
