  • Ten ways to minimize grate wear in a waste-to-energy boiler

    A low fuel layer provides a small buffer of fuel on the grate, and small variations in the fuel can lead to large variations in energy production. If the layer is smaller, the combustion reaction rate increases and the combustion zone moves up the grate. When the grate is exposed, it faces direct radiation and flue gas, thus increasing grate wear.Learn More

  • Biomass Boilers Maintenance Precautions - Industrial

    Jun 16, 2021 · Biomass boilers tend to coke during the fuel combustion process, which leads to poor furnace fires and burned grates in the boiler.
