Chain grate is a kind of common mechanized combustion equipment, which is used for biomass boiler, coal-fired boiler and thermal oil heater. The grate is used to make the solid fuel burn evenly. The fuel enters the grate through the hopper, and enters the hearth with the movement of the grate to start the combustion process. According to different fuels, ZOZEN Boiler also designs different grate widths and lengths and air distribution systems to ensure that the fuels can be stably ignited and fully burned.
