  • Coal or multifuel burner
    Patent number: 4493271
    Abstract: The object of the invention is to permit, for operation with coal by itself, easy adjustment of the flame length without varying the gas flow and with a relatively stable flame divergence. The burner according to the invention comprises a cylindrical tube (1) through which an air/fuel mixture is ejected into the flame, and inside which a coaxial cylindrical part (6) can move along the axis in order to permit adjustment of the output speed of the gas. Advantageously, this part (6) constitutes a means for injecting air and fuel-oil for mixed operation or operation with fuel-oil by itself.
