摘要： 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.

摘要： Air bled from an air compressor of a gas turbine is taken into a booster via an inlet guide vane. Air compressed by the booster is supplied to a gasifier via an air supply valve. An air pressure controller controls the opening of the inlet guide vane by feedback control and, when a gasifier load command changes, priorly controls the opening of the inlet guide vane immediately in response to this change.

摘要： A control apparatus of an extracted air booster system of an integrated gasification combined cycle power plant can additionally serve a sufficient pressure control function and a sufficient antisurge control function. For example, when an inlet guide vane is fully closed or has a small opening degree equal to or smaller than a predetermined opening degree, a second control section of the control apparatus performs pressure control based on a pressure deviation, instead of or as well as antisurge control. In the pressure control, the degree of opening of an antisurge valve is controlled so that a booster outlet pressure detection value can become equal to a set pressure value. In a case where a pressure ratio is larger than a set pressure ratio value, it is also effective that the second control section performs the antisurge control even when the inlet guide vane is fully closed.
