    Patent number: 7997084
    Abstract: A gasifying furnace gasifies solid fuel or liquid fuel. A gas turbine drives a turbine to generate power by using combustion gas generated by burning mixed gas of compressed air compressed in a compressor and gas generated in the gasifying furnace in a combustor. A booster boosts compressed air bled from the compressor, and feed the compressed air to the gasifying furnace. A bleed source valve is provided in a bleed line between the compressor and the booster. An abnormality stop controller stops the booster and the gas turbine, based on an opening angle of the bleed source valve or a bleed pressure on an upstream side of the bleed source valve.
