PURPOSE:To enable to control fuel so as to flow smoothly and stabilizedly, by largely increasing and decreasing the ratio of pressure under an atomizing medium to the fuel pressure in accordance with the increase and the decrease of the rate of fuel flow at the time when liquid fuel is burning, in comparison with the time when slurry of solid fuel is burning. CONSTITUTION:The pressure under slurry of solid fuel is fed into a differential pressure gauge 17 through a pipeline 15, as well as to feed the pressure under an atomizing medium through a pipeline 14. Based on the differential pressure DELTAP1, a pressure control valve 13 is controlled through a pipeline 19. On the other hand, the pressure under liquid fuel is fed into a differential pressure gauge 18 through a pipeline 16, as well as to feed the pressure under the atomizing medium through the pipeline 14, and based on the differential pressure DELTAP2, the pressure control valve 13 is controlled through the pipeline 19. The differential pressure gauges 17 and 18 control the atomizing medium by the pressure control valve through the pipeline 19 in accordance with the change in pressure under each fuel, so as to become a predetermined differential pressure respectively, corresponding to the kind of fuel to be burned. |
