Grate bar Medium1.4776
Application of grate in boiler
Support fuel: in coal-fired boilers, biomass boilers and other boilers, the grate can provide stable support for coal, wood, biomass and other fuels, so that the fuel can be burned in an orderly manner in the furnace, to ensure the stability and sustainability of the combustion process.
Promote combustion: grate can make the air from below through the ventilation pores, full contact with fuel, for fuel combustion accurately supply oxygen, thus improve combustion efficiency, make fuel combustion, release more heat, and heating water in the boiler to produce steam, used for power generation, industrial production or residential heating, etc.
Transmission fuel: part of the grate will be designed to rotate or reciprocating form, which can drive the fuel from the feeding end to the discharging end, so that the fuel gradually through different combustion areas in the furnace, to achieve continuous and stable combustion process.
Sewage discharge: the grate is usually equipped with sewage holes. In the process of fuel combustion, the ash and impurities can be discharged in time to keep the boiler clean and prevent the accumulation of ash from affecting the combustion effect and the normal operation of the boiler.
1.4776 is a kind of heat resistant steel material, belongs to the European label number (GX40CrSi28), with excellent high temperature resistance, oxidation resistance and wear resistance, widely used in industrial furnace, boiler, combustion equipment and other fields. Here is the specific information about the 1.4776 material:
