A bottom gas burner has an air pipe with narrowed output section, with fuel-supply unit installed at axis of the pipe, and convex, made with openings hollow mixing-distribution element installed in front of the pipe end on holder. Mixing-distribution element is separated by partition, lower part by means of hollow holders is connected to the source of supply of saturated gas-air mix, and the upper one - to the source of supply of steam-air mix. Such implementation of the bottom gas burner makes it possible to provide process of burning of fuel with low output of nitrogen oxides.
