LOAD ADJUSTMENT TYPE LIQUID FUEL BURNER, AND LOAD ADJUSTMENT TYPE LIQUID FUEL COMBUSTION METHOD

PROBLEM TO BE SOLVED: To provide a load adjustment type liquid fuel burner capable of establishing the technology to simultaneously realize the stable combustion and the enlargement of a load adjustment range, and to provide a load adjustment type liquid fuel combustion method. SOLUTION: This burner is composed of a first burner 1 and a second burner 2. The first burner 1 is composed of a first outer pipe 3, a first inner pipe 4, a partition pipe 5 and a first nozzle 31 at a head side. The second burner 2 is composed of a second outer pipe 8, a second inner pipe 9 and a second nozzle 43. The flow rate characteristic of the first burner 1 and the flow rate characteristic of the second burner 2 are independent from each other, and the amount of fuel supplied to a first fuel supply passage 6 and that of the second fuel supplied to a second fuel supply passage 11 are independently adjusted. As both flow rate characteristics are independently activated when necessary, the stable combustion and the enlargement of the load adjustment range are simultaneously realized. A concentric structure of the first burner 1 and the second burner 2 makes the adjacent structure of the first nozzle and the second nozzle easy and simple. COPYRIGHT: (C)2004,JPO
