Abstract
PURPOSE: To decrease NOX while stabilizing combustion by a mechanism wherein a plural stage of air nozzles and exhaust gas nozzles are alternately arranged in concentric circle shapes centering around a main burner, and mixing among exhaust gas, air for combustion and fuel is improved.
CONSTITUTION: One portion of air 8 for combustion is supplied as primary air 9. Primary exhaust gas is circularly jetted by means of primary exhaust gas nozzles 16 from the primary air 9 and the circumference of flames, and secondary air is annularly ejected through secondary air nozzles 15 from the circumference of the primary exhaust gas. Secondary exhaust gas is jetted from secondary exhaust gas nozzles 14, whose insides have gas burners 2. In this case, air is supplied to the gas burners 2 so that the secondary air ejected from the secondary air nozzles 15 and tertiary air 13 fed from another system be joined and the theoretical quantities or more of air of the gas burners 2 be produced. Thus, the mixing of exhaust gas is improved by supplying air for combustion and exhaust gas in stratiform shapes at plural stages.
