Gas supply control device for combustor

A gas supply control device for a combustor comprises a main solenoid valve, a switching valve, a pressure stabilizing valve and a kindling solenoid valve, wherein the gas inlet end of the main solenoid valve is connected with a fuel gas inputting pipe, the gas outlet end of the main solenoid valve is connected with the switching valve, and the switching valve is provided with two gas outlet ends which are connected with the pressure stabilizing valve and the kindling solenoid valve respectively. The gas supply control device is characterized by further comprising a main gas distributing pipe, a main fire fuel gas pipe and at least two gas distributing solenoid valves; one end of the main gas distributing pipe is connected with the gas outlet end of the pressure stabilizing valve, and the other end of the main gas distributing pipe is closed; one end of the main fire fuel gas pipe is closed, and the other end of the main fire fuel gas pipe is connected with the combustor; each gas distributing solenoid valve is composed of a valve body and an electromagnetic assembly, wherein the valve body is provided with a gas inlet pipe, a gas outlet pipe and a valve core cavity, the gas inlet pipe of each gas distributing solenoid valve is connected with the main gas distributing pipe, and the gas outlet pipe of each gas distributing solenoid valve is connected with the main fire fuel gas pipe. The gas supply control device is simple in structure and convenient to operate, the supply of fuel gas needed by the combustor can be adjusted, stable control over heat power generated by the combustor is ensured, the combustion efficiency is improved, and waste of the fuel gas is prevented.
