At drum oil-gas boilers with front two-layer layout of vortex burners (for example, at boilers TGM-84, TGM-151-B, etc.) a gas combustion mode, using one and two burner layers, is practiced. When burning oil to raise a temperature of the superheated steam, burners of the third layer, are put into operation.
