Product Introduction
SZL series coal chain grate boiler adopts water-tube structure, featuring wide fuel adaptability for coal and biomass fuels. With high thermal efficiency and strong overload capacity, it achieves world-class advanced performance.
SZL Water Tube Biomass coal Boiler System
Core Advantages
a. Membrane water cooling wall structure: achieve large heat transfer area, high heat transfer efficiency, low heat loss, good air tightness.

b. Inverted α furnace arch design: available to burn various biomass. It design can burn biomass fuels such as rice husk, wood, bagasse, straw, sawdust, sunflower shells.

c. Long grate, strong overload capacity: the actual heating surface of the grate is increased and the overload capacity is remarkably enhanced.

d. Burning effect is good: wind is feed from both sides of the boiler.
