What is the highest temperature that a chain grate can generally bear?

Chain grate boiler is a kind of mechanized combustion boiler equipment which is widely used in industrial boilers. The chain grate is an important part of the grate, which is a consumable part. It is in direct contact with the burning fuel, so the selection of heat-resistant temperature is especially important. What is the highest temperature that a chain grate can generally bear?

Generally, the high temperature that chain grate can bear is directly related to the material. The heat-resistant temperature of gray cast iron HT is 200-300℃, that of medium silicon nodular cast iron RQTSi5 is 900℃, and that of silicon aluminum heat-resistant cast iron is 1000℃.

During the operation of the boiler, the grate pieces are always in a high-temperature working state, with the average temperature reaching 350℃-450℃ and the high temperature reaching 450℃-550℃, and the local temperature will be higher, especially the ash fusibility of biomass fuel is low, and the grate even directly touches the high-temperature flame.

The low heat-resistant temperature of the chain grate is easy to cause high-temperature burning and deformation of the chain; The chain grate has higher heat-resistant temperature, which increases the cost. Therefore, it is very important to choose the appropriate high-temperature resistant grate material for chain furnace, which can improve the reliability of grate and ensure the safe production of boiler.

It is important to know how many degrees of high temperature users can generally bear, but how to choose the appropriate grate is even more critical. Here, we suggest you consult a professional boiler manufacturer. ZOZEN Boiler has been designing and manufacturing chain grate boilers since its establishment, with mature technology and fruitful results, and has obtained many national patents. At present, the company's biomass chain grate boilers cover DZL, SZL, DHL, SHL four series industrial boilers and ZZ series power generation boilers, which can be applied to bituminous coal, anthracite, biomass particles, sawdust, palm shells, straw and other fuels. ZOZEN Boiler has rich experience in what is the highest temperature that a chain grate can generally bear.
