| 摘要 |
An improved gas burner comprising a gas nozzle having a first flame stabilizer mounted to the front end thereof and a plurality of gas blow apertures arranged circumferentially therein adjacent to the first flame stabilizer, a second flame stabilizer having a plurality of secondary combustion air passages arranged in the circumferential end thereof and a primary combustion air passage arranged in the center thereof which is defined by the outer surface of the gas nozzle, and a burner cone accommodating the second flame stabilizer coupled to the inner wall thereof, said gas burner being improved for reducing unwanted nitrogen oxide and/or uncombusted gas, characterized in the positional relation between the flame stabilizer(s) and the gas blow apertures, the novel construction in which the shape of the flame stabilizer is designed for optimum function with association with its positional relation, the novel arrangement in which the flame stabilizer can be controlled for optimum positioning, and the improved burner head arrangement for producing a ring of separate combustion flames.
