METHOD TO GENERATE BURNING BY MEANS OF ASSEMBLED BURNER AND ASSEMBLED BURNER Russian patent published in 2013 - IPC F23D14/22 F23D14/32 F27B1/08 

FIELD: power engineering.

SUBSTANCE: method to generate burning by means of an assembled burner comprising a refractory unit, a fuel supply system and an oxidant supply system, besides, the refractory unit sets along the first plane at least one channel for fuel stretching from an inlet port for fuel to an outlet port for fuel, and substantially along the second plane, at least one channel for an oxidant stretching from an inlet port for an oxidant to an outlet port for an oxidant, besides, the specified first and second planes cross along the line, which is at the distance from the specified outlet ports, the specified system of oxidant supply comprises an inner facility for oxidant supply, comprising an inlet connected with the source of the first oxidant and an outer facility for oxidant supply, which at least partially surrounds the inner facility of oxidant supply and which comprises an inlet connected with the source of the second oxidant, the specified inner and outer facilities of oxidant supply stretch at least partially into one channel for oxidant, and the specified system of oxidant supply is made as capable of supplying to the outlet port of the specified at least one channel for oxidant, or only one of the specified first and second oxidant or their combination, besides, the method includes stages, at which: optionally, the first oxidant is supplied to the inner facility of channel oxidant supply for a refractory unit oxidant, besides, the specified first oxidant preferably contains at least 70 vol. % of oxygen, preferably at least 90 vol. % and more preferably at least 95 vol. %; optionally, the second oxidant is supplied to a concentric outer facility for supply of an oxidant of the same channel for the oxidant, besides, the specified second oxidant preferably contains less than 25% oxygen and is preferably air; the ratio is changed between the specified first and second oxidants supplied at least to one channel for the oxidant between supply of only the first oxidant to the inner facility of oxidant supply, supply of only the second oxidant to the concentric outer facility of oxidant supply and supply of combination of the first oxidant to the inner facility of oxidant supply and the second oxidant to the concentric outer facility of oxidant supply, and the specified oxidant or oxidants are sent to fuel for its burning downstream the assembled burner.

EFFECT: invention makes it possible to improve quality of fuel burning.
