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), is closed at its tip (4a), and has at least one combustion supporting gas supply port at its juxta-tip lateral part (4b). A central axis of the combustion supporting gas supply tube (4) at the juxta-tip lateral part (4b) is generally parallel to a longitudinal direction of the tubular mixing section (1).
