Abstract

PURPOSE:To prevent the occurrence of poor combustion due to dripping during the initial stage of ignition, by a method wherein a burner is mounted in a sloped state so that its front is lowered. CONSTITUTION:A burner mounting cylinder 12 is mounted in a state in which it is inclined based on a combustion chamber 13. Primary air enters through a hole 9 of a partition plate 8 and is fed through a nozzle hole 5 to the interior of a vaporizing cylinder 6. Secondary air is fed through pores 3 and 4 of an inner cylinder 2 to the interior of the inner cylinder 2. Fuel is sprayed through a fuel injection nozzle 10 and collided with a vaporizing cylinder 7 after flowing through the nozzle hole 5 for gasification. The gasified gas is mixed with secondary air fed through the pores 3 and 4 of the inner cylinder 2 to form flame 14 and flame 15. By means of the radiant heat of the flame 14, the vaporizing cylinder is heated, gasification of the fuel is promoted, and the bottom part of the inner cylinder 2 is heated by means of the flame 15 to prevent staying of sprayed fuel. During the initial stage of ignition, since the temperature of the vaporizing cylinder 7 is lower, the sprayed fuel is collided with the vaporizing cylinder 7, and is dropped on the inner cylinder 2. The fuel dropped on the inner cylinder 2 is drained from the front of a burner, flows through the burner mounting cylinder 12, and is guided to a combustion chamber 13.
