An igcc plant includes a coal gasifier that gasifies coal by using an oxidizer, a gas turbine that is driven by combustion gas generated by combustion of fuel gas obtained by purifying gas generated by the coal gasifier in gas clean-up equipment, and an oxidizer supply path for supplying air extracted from an air compressor of the gas turbine or oxygen separated from the air as an oxidizer for the coal gasifier. A control unit (50) for the gasification power generation plant controls the amount of the oxidizer that is supplied to the coal gasifier to be less than or equal to a predetermined upper-limit value, while allowing deviation of an air ratio from a predetermined set value, the air ratio representing the ratio of the amount of air that is supplied to the coal gasifier relative to a theoretical amount of air for combustion of carbon, in accordance with variations in an operating-state quantity of the coal gasifier or variations in a load of the igcc plant.

An exhaust-gas turbocharger with a compressor with a charge pressure control device. An actuator is provided which moves a control rod arrangement.
Methods and system for determining compressor recirculation valve sludge
Systems and methods for determining the presence or absence of deposits that may accumulate within a compressor recirculation valve positioned in parallel with a turbocharger compressor are presented. The systems and methods adjust actuators to maintain engine operation such that it may be more difficult for a driver to become aware that a compressor recirculation valve diagnostic is being executed..
