SZL coal fired steam boiler is specially designed and optimized for applications to produce low and medium pressure steam or hot water with rated evaporation capacity from 2 to 35 ton/hr and rated pressure from 0.7 to 2.5 MPa. The design heat efficiency of SZL coal boiler is up to 81~82%. Technical Data of SZL Coal Fired Steam Boiler

Similar to coal fired boiler, SZL series biomass boilers also has the characteristics of big heating surface, high thermal efficiency, little fuel leakage, separate air chamber, sufficient burning, variable frequency control and PLC automatic control, etc al. SZL series biomass fired boiler is often used as biomass steam boiler to generate low pressure steam with rated evaporation capacity of 6-35 tons/h …

The new type SZL water-cooling sealing assembly chain grate series boiler is the new assembly boiler developed by Zhongding Boiler and Xi’an Jiaotong University.

SZL series biomass chain grate boilers with high efficiency, strong overload capacity and various fuel adaptability (biomass pallet or coal), are well known as the best design among contemporary domestic similar products and have reached the world's advanced level.

SZL series coal fired chain grate boiler is a good example. Membrane water cooling wall structure in combustion chamber, good sealing to prevent heat loss. It is widely used in textile factory, paper factory, food industry, generating steam in industry process. SZS series water tube boilers were sold to Iran, Mongolia and Vietnam.

Zhongding boiler takes several breakthroughs on boiler design, such as membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber. The convection heating area increase more than 50%, and by using the light furnace wall, the thermal inertia decrease 70%, to improve thermal efficiency.
