What is the meaning of chain grate boiler?

The chain grate boiler is a layer-fired boiler with a high degree of mechanization. Its grate is similar to the crawler of the chain, so this kind of boiler is called a chain grate boiler. Moreover, it is a front-mounted boiler, and the combustion process of coal is completed on the move. The advantages of this type of boiler are stable combustion conditions, high thermal efficiency and simple and convenient operation, and in addition, its smoke and dust emission concentration is low. However, it should be noted that coal with high moisture content, high ash content and strong coking property is not suitable for combustion in this type of boiler.

The coal-fired chain grate boilers produced by Yuanda Boiler can be divided into two series: SZL series double drum chain grate boilers and DZL series single drum chain grate boilers.

Yuanda coal-fired boilers have a wide range of fuel applicability, and can be applied to various coal types such as bituminous coal, anthracite, lean coal, lignite, etc. At the same time, special grate pieces are selected to ensure smooth operation of the grate; the combustion-supporting air system (base) adopts independent sub-silo and Scientific sealing structure; reasonable air regulating device to achieve precise air distribution and improve combustion efficiency.
