MIXING APPARATUS OF COMBUSTIBLE GAS AND COMBUSTION SUPPORTING GAS

摘要

A mixing apparatus (10A) comprises a tubular mixing section (1) for mixing a combustible gas and a combustion supporting gas; a combustible gas supply port at one end (1a); 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); and a combustion supporting gas supply tube (5) connected to the tubular mixing section (1) between the one end (1a) and the other end (1b) for supplying the combustion supporting gas into the tubular mixing section (1) from a combustion supporting gas supply port (5a). The combustible gas transport device (3) can control a flow velocity of the combustible gas at the combustion supporting gas supply port (5a) not less than a combustion velocity of the mixed gas.
