Description
【発明の詳細な説明】 本発明は、過給機の運転方法に関する。[Detailed description of the invention] The present invention relates to a method of operating a supercharger.

溶け、溶融状態で象り出すと逅ができるものである。There is a cyclone furnace, which is a coal-burning furnace. This process involves blowing powdered coal into a cylindrical combustion chamber, blowing combustion air so as to scrape the inner surface of the cylindrical combustion chamber, and burning under high load. It is something that can be enjoyed when visualized in a state.

、送風機の動力はさらに大きくなるものである。There are S ways to externally cool the cyclone furnace; one is water cooling (usually by wrapping a water pipe around it) and the other is air cooling. However, in either case, the combustion air needs to be swirled at high speed within the cylindrical combustion chamber, resulting in an extremely large pressure loss, and the power of the blower becomes excessive. Therefore, even if we take into account that the power of the pulverizer is reduced by decreasing the amount of pulverized coal particles, the power consumption is significantly greater than that of a pulverized coal combustion furnace. In addition, in the case of water cooling, it is necessary to raise the temperature of the combustion air by 1 second in order to melt the coal ash, and for this purpose air preheating lI' is provided, but the ventilation resistance is large. Furthermore, in the case of air cooling, it is necessary to increase the flow velocity of the cooling air flowing through the cooling passage around the outer periphery of the cylindrical combustion chamber in order to enhance the cooling effect, which increases the ventilation resistance. Therefore, in both water cooling and air cooling, the ventilation resistance increases further, and the power of the blower becomes even greater.

As a method, a device having a high-temperature body inside is cooled by air from the outside, and the high-temperature air is used to drive a gas turbine, and the power is used to drive a compressor, thereby transferring the obtained compressed air to the device. The present invention aims to provide a supercharging-like operating method 1, which is characterized in that the compressed air exiting the turbine is supplied as the cooling air of the turbine, and the compressed air exiting the turbine is supplied as the combustion air of the device.

is a cylindrical combustion chamber with a cylindrical cylinder.Pulverized coal is blown into the combustion chamber 1 through an opening 2 at one end by a burner (not shown), and combustion air is blown into the combustion chamber 1 through the opening 2 or through the combustion chamber 1. The fuel is blown into the combustion chamber l from the mouth 8 which is opened in the tangential direction and swirls into the combustion chamber l. Combustion gas from the combustion of pulverized coal in the combustion chamber 1 exits from the opening at the other end of the combustion chamber 1 and enters, for example, a boil combustion chamber (not shown) to heat it.The ash of the pulverized coal is melted and becomes liquid. It flows out from an opening (not shown).

周の通路６′内に入や、咳通路６′内を流れる。Since the cylindrical combustion chamber 1 is air-cooled, the inner surface of the combustion chamber 1 is lined with a refractory material 5, and the outer periphery is provided with cooling air passages 6,
6' is provided twice in a folded manner, and the cooling air is sucked from the atmosphere into the compressor 8 as shown by the arrow F, becomes compressed air, passes through the air pipe 9t, and exits from one end of the cooling air passage 6. It enters the passageway 6, flows through the passageway 6, enters the passageway 6' on its outer periphery from the other end, and flows inside the cough passageway 6'.

As the gas turbine 11 is driven, the compressor 8 on the same axis is driven, and the cooling air blown in from the atmosphere as shown by the arrow 7 is compressed. The air exiting the gas turbine 1it has the necessary pressure as combustion air and is passed through the air pipe 1.

化に貢献するところ大なるものがある。As can be seen from the above explanation, according to the method of operating a supercharger of the present invention, it is possible to overcome the ventilation resistance of the cooling passage in a device that contains high-temperature bodies such as combustion, gasification, melting, and heating. Since it is easy to obtain cooling air and combustion air at a pressure that allows it to swirl at high speed in the combustion chamber, it is possible to increase the air velocity to increase the cooling effect of the cooling air as in the past. There is no increase in resistance, no increase in pressure loss due to high-speed swirling of combustion air, and no increase in power consumption, which greatly contributes to energy savings.
