Chain-grate boilers With dual-fuel coal and biomass

2026-07-23 23:35:16 Many of XHJ’s customers have been asking: Can coal and biomass be burned in the same boiler?
 
Today, we’ll address this question: Yes, they can be used in the same boiler—specifically, a chain grate boiler. Chain grate boilers are currently one of the most mature boiler types in industrial applications. Because the grate operates continuously and combustion is stable, these boilers can burn not only coal but also a variety of biomass fuels.
   
Why is it dual-fuel capable?
 
The chain grate features continuous fuel feeding and can accommodate fuels such as bituminous coal, anthracite, lignite, wood pellet, palm kernel shells, wood chips, corn cobs, peanut shells, and rice husks.
 
By adjusting the grate speed and the forced and induced draft systems, the boiler can adapt to the combustion characteristics of different fuels.
 
Advantages of dual-fuel boilers: greater flexibility in fuel selection, lower energy costs, the ability to switch fuels based on market prices, and reduced operational risks for businesses.
   
As a result, chain grate boilers have become a key choice for many industrial enterprises. As a professional industrial boiler manufacturer, XHJ offers high-quality chain grate boilers capable of burning both coal and biomass.
