Abstract

PURPOSE:To obtain a good state of comnbustion even when flow is controlled at a fine rate and to reduce NOx by making up the sectional areas of injection nozzles of fuel gas, primary secondary air so that they can be controlled in the range of the full cut-off to the full admission. CONSTITUTION:Fuel gas (a) is supplied from a supply pipe 10 to a tapering nozzle hole 1 and the sectional area of a fuel gas supply part is controlled by moving the core 2 of a tapering cylindrical gas nozzle in the axial direction through a rod 3. The primary air (b) is supplied from a supply pipe 11 to the part of the tapering nozzle hole 4 and the sectional area of the supply part is controlled by moving a tapering nozzle core 5 similarly. Further, the secondary air (c) is supplied from a supply pipe 12 to the part of a nozzle hole 7 and the sectional area of the supply part is controlled by moving a circular nozzle core 8 similarly. Fuel gas and the primary air are mixed in a premixing chamber 16 and burnt under the state of short air. Then, complete combustion is conducted by supply of the secondary air.
