ABSTRACT:
A method and an apparatus for burning gaseous fuel, the composition of the fuel varying at times, wherein; main injection ports and sub-injection ports are arranged in such positions that the fuel injected through the sub-injection ports may be ignited by a flame formed from the fuel injected through the main injection ports; fuel passes are provided or conducting the gaseous fuel separately to the two groups of injection ports; and control valve is provided for adjusting the ratio of the fuel flow to the main injection ports to the fuel flow to the sub-injection ports; whereby the proportion of the fuel to be injected through the main injection ports is increased as the rate of burning the gaseous fuel increases.
