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.

How to Improve Combustion Efficiency of Traveling Grate Boiler

Oct 19, 2020 · Combustion characteristics of chain grate. The ignition condition of chain grate is poor. The coal fires mainly depend on the radiant heat of the furnace flame and the arch, so the coal above fires first and then burns down gradually. As a result of this combustion process, distinct regional stratification appears on the grate, as shown in Figure 3-11.
