MIXER OF COMBUSTIBLE GAS AND COMBUSTION SUPPORTING GAS

摘要

A mixer (10) for mixing a combustible gas and a combustion supporting gas comprises a tubular mixing section (1) which extends between one end (1a) having a combustible gas supply port (2) and the other end (1b) having a mixed gas discharge port (3); and a combustion supporting gas supply tube (4) which is inserted into the tubular mixing section (1) between the one end (1a) and the other end (1b) of the tubular mixing section (1) and has a combustion supporting gas supply port (5) at its tip (4a) to open towards the other end (1b) of the tubular mixing section (1). A juxta-tip part (4b) of the combustion supporting gas supply tube (4) has an outer shape tapered towards the combustion supporting gas supply port (5) at the tip (4a).
