【発明の名称】ガスタ-ビンユニツト作動方法
Document Type and Number:
Japanese Patent JP2540539
Kind Code:
B2
Abstract:
The invention relates to a method of operating a gas turbine unit comprising a combustion chamber, a high pressure turbine driven by gas from the combustion chamber, and a low pressure turbine driven by gas from the high pressure turbine, means for controlling the gas supply from the high pressure turbine to the low pressure turbine, and a low pressure compressor driven by the low pressure turbine, and a high pressure compressor connected in series with the low pressure compressor and driven by the high pressure turbine for supplying pressurized air to the combustion chamber, the useful power of the gas turbine unit being adjustable by controlling the gas conditions upstream of the low pressure turbine by said means. Substantially all the air delivered to the combustion chamber from the compressors, is utilized for the combustion in the combustion chamber. The generated gas is cooled with water and/or steam to a temperature which corresponds to the maximum operating temperature of the high pressure turbine. There is made use of the power obtained from the combustion chamber by said cooling, and the useful power of the gas turbine unit is recovered from the high pressure turbine at substantially constant rotational speed thereof. The temperature of the gas supplied to the high pressure turbine is maintained substantially constant independently of the useful power recovered from the gas turbine unit.
