MIXING APPARATUS OF COMBUSTIBLE GAS AND COMBUSTION SUPPORTING GAS

摘要

PROBLEM TO BE SOLVED: To provide a mixing apparatus of a combustible gas and a combustion supporting gas having a low pressure drop. SOLUTION: The mixing apparatus (10) includes a tubular mixing section (1) for mixing the combustible gas and the combustion supporting gas; a combustible gas supply port at one end (1a) thereof; a combustible gas transport device (3) for supplying the combustible gas into the tubular mixing section (1) from the combustible gas supply port; a mixed gas outlet port of the combustible gas and the combustion supporting gas at the other end (1b) of the tubular mixing section (1); a combustion supporting gas supply tube (5) for supplying the combustion supporting gas into the tubular mixing section (1) from a combustion supporting gas supply port (5a); and a baffle plate (7) installed between the one end (1a) of the tubular mixing section (1) and the combustion supporting gas supply port (5a) in the tubular mixing section (1). The combustible gas transport device (3) can control a flow velocity of the combustible gas swirled by the baffle plate (7) at the combustion supporting gas supply port (5a) not less than a combustion velocity of the mixed gas of the combustible gas and the combustion supporting gas.
