FIELD: power industry. ^ SUBSTANCE: in method for obtaining hot gaseous heat carrier (the first version) the gaseous fuel is supplied to modules of gas burner system to inter-blade space of input axial bladed swirlers; at that, gas-air mixture leaving the inserts of modules is swirled by means of outlet axial bladed swirlers in the direction opposite to direction of mixture swirling at inlets to inserts to modules; at that, flow swirling of secondary air is performed by means of bladed axial swirlers at the inlet of combustion chamber and tertiary air at combustion chamber outlet by its being mixed with mixture of air and combustion products, which leaves the combustion chamber. In method (the second version) the initial air is supplied to cavity between walls of housing of heat generator and combustion chamber. In gas generator the gas distributing holes of gas supply branch pipe are located inside inter-blade space of inlet axial bladed swirler, and at insert outlet there installed is outlet axial bladed swirler having the possibility of swirling gas-air mixture opposite to swirling direction in inlet axial bladed swirler; at that, in interconnection places of inner cavity of combustion chamber and cavity located before gas burner system, at combustion chamber inlet, as well as at interconnection point of annular cavity between walls of housing of heat generator and combustion chamber with combustion chamber outlet there installed are axial bladed swirlers. ^ EFFECT: higher fuel combustion efficiency, lower fuel flow and improved heat carrier quality. ^ 10 cl |
