Abstract

PURPOSE: To increase the number of stages of combustion capacity by disposing combustors formed of predetermined number of burning tubes at its center and both sides, connecting capacity switching valve to the combustors of both sides, igniting the central combustor at the time of an initial ignition to always burn it, and transferring its flame to the combustors of both sides.
CONSTITUTION: An original gas solenoid valve 8 and an emergency gas solenoid valve 9 are opened at the time of an initial ignition, mixture ratio of gas and combustion air is set to a state to be easily ignitable of a slow ignition state under the control of a proportional valve 10 and an air supply fan 3, and a central first combustor 21 is ignited. In this case, capacity switching valves 11, 12 are closed. The combustor 21 is always burned during a normal combustion, gas is supplied to second and third combustors 22, 23 of both sides to transfer its flame by opening and closing the valves 11, 12, and the combustion capacity can be switched to four stages by the combination of the opening/ closing states of the valves 11, 12.
