Our chain grate stokers and reciprocating grate stokers are used  together with 1-160 t / h, thermal power of 0.7-112MW for biomass boilers,industrial boilers,garbage waste incineration burners of energy electric power plants, organic heat carrier furnaces, hot air drying furnaces and other relative products.

The boiler economizer is a device designed to increase operating efficiency of the boiler because of cutting down on its operational costs over the lifetime of the boiler. Although the savings on any given day may be relatively small, the impact over time can be significant; some boilers are designed with economizers built in, and in the other cases, the economizer can be fitted on afterwards. boiler economizer acts as the waste heat recovery device, ensuring that this heat does not go unused. Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to a temperature high enough to make steam. It is a part of Chain grate boiler system.
