<p>PROBLEM TO BE SOLVED: To provide a combustion equipment which can make low-NOx combustion equally to the case where gas fuel is used even when the equipment uses liquid fuel, such as kerosene, A oil, etc., and can complete combustion at a low air ratio. SOLUTION: This combustion equipment is provided with a bar-like fuel supplying section 1 which sprays fuel from its front end, an annular air chamber 8 formed of an inner pipe and an outer pipe nearly coaxially to the section 1, a plurality of air supplying openings 10 made through the front end face 6 of the chamber 8 which blocks the space between the front ends of the pipes 2 and 5. This equipment is also provided with a vane member 7 which has openings 11 and 12 from which a plurality of kinds of air for combustion is blown out correspondingly to the combustion amount and can rotate around the bar-like fuel supplying section 1. The vane member 7 is positioned adjacently to the front end face of the air chamber 8 so that the areas of the air supplying openings 10 may be adjusted by aligning the openings 10 with the openings 11 and 12 of the vane member 7.</p> |
