A hearth burner includes an air chamber placed under the slot of the hearth, and in the slot of the boiler hearth gas collector with openings at side surface with diameter that is equal to width of slot, and equipped with placed in gas collector normally to its horizontal axis by whole length air tubes with openings in side surface, both ends of those are placed outside the collector, the openings on the side surface of the collector are arranged around the outlet ends of the air tubes in circle diameter of which is larger than the diameter of the air tubes. The hearth burner is equipped with two gas transport tubes with different lengths placed along the gas collector in parallel to its horizontal axis, with diameter equal to half of difference of the inner diameter of gas collector and the air tube.
Oxygen lance characterized in that it has at least three tubes arranged coaxially with each other and that delimit at least one annular groove, the outermost tube for the passage of superheated steam being made and presenting a steam supply point, the central tube being made as an annular groove, the innermost tube being made for the passage of hot oxygen with a maximum temperature of 180 ° C and presenting an oxygen supply point.
