alumina refractory product for furnace burner, Burner refractory brick
alumina refractory product for furnace burner, Burner refractory brick
Product Description
The burner brick is also called burner, is the industrial fuel furnace with the combustion device commonly known as, can be understood as the "fire nozzle" abbreviation.Usually refers to the combustion device body part, there are fuel inlet, air inlet and jet hole, play a distribution of fuel and combustion air and in a certain way after the role of combustion.
There are different materials for burner block, including chromium corundum, corundum mullite, high aluminum mullite, clay, silicon carbide and so on, to satisfying the requirements of different use temperatures.
Sized or shape: Customized according to customer's requirements or drawings
The functions of the burner brick are:
1) heat the fuel in the burner block to the ignition temperature to facilitate ignition and rapid combustion.
2) maintain a certain high temperature in the burner brick to stabilize the combustion process and avoid pulsation or combustion interruption.
3) organize flame shape to meet the requirements of heating process.
4) mix the fuel and air further.
