| titleOfInvention | Method and device for transporting solid fuel powder into combustor of open-cycle gas turbine for combustion and generating work |
| abstract | This invention relates to a method and device for transporting solid fuel powder into combustor of open-cycle gas turbine for combustion and generating work. The fuel-suppliers have three types: the first type is magnet-driven non-shaft seal helical fuel supplier, the second type is a fuel supplier in which the driver and a helical fin are installed inside a sealing case, and the third type is the fuel supplier in which a shaft sealing device is equipped between the sealing cases of the driver and the helical fin, and one of the three types of fuel supplier can be randomly selected. The air has to be pre-heated to a very high temperature level before entering the compressor so that the temperature of the compressed air is higher than the spontaneous combustion temperature of fuel, (e.g. around 540 degree Celsius for beech powder) so as to enter the combustor for assisting combustion. Moreover, the system is equipped with high-pressure easily combustible auxiliary fuel for assisting the combustion demand when solid fuel is not easy to be burned at the beginning of system operation or when the system temperature drops down. The system is also equipped with a small air compressor (with a pressure accumulator) for introducing cooled high pressure air into the sealing case of the helical fuel supplier and fuel storage tank so that its pressure is always and slightly higher than that of the combustor to prevent the burned gas from flowing into the fuel supplier, thereby resulting in burning and damaging the components. A conduction pipe is equipped between the pressure accumulator and the high-temperature and high-pressure air storage tank so that the high-pressure air in the pressure accumulator will enter the combustor at the beginning of system operation through the tank to allow the power instantly reaching full capacity. A small conduction pipe is disposed between the pressure accumulator and the top of the water supplying tank so that the supplied water at the nozzle has a spraying pressure. Before entering the compressor, air is mixed with a small amount of waste gas exhausted from the gas turbine to raise the temperature rapidly. The lower half part of the combustor is equipped with a L-shaped elbow pipe flame-resistance inner furnace for preventing fierce flame from being directly in contact with the combustor wall. A fire-resistant porous mask is equipped between the inner furnace and the combustor wall. The combustor wall on the top of the mask is equipped with automatic hot water (or steam) spraying device to prevent the combustor from being burned and damaged due to extremely high temperature of combustion gas. |
