Abstract

The invention discloses an intercooling regenerative cycle combustion gas turbine system and relates to the technical field of combustion gas turbines. The intercooling regenerative cycle combustion gas turbine system comprises a high-pressure turbine, a regenerator, a low-pressure turbine, a power turbine and an afterburning combustion chamber, wherein the afterburning combustion chamber is arranged between the high-pressure turbine and the low-pressure turbine; fuel gas exhausted out of the high-pressure turbine is burnt and heated again through the afterburning combustion chamber, and the temperature of fuel gas entering the low-pressure turbine is increased; fuel gas drives the power turbine after being subjected to expansion work through the low-pressure turbine; heat energy of exhausted gas of the power turbine is absorbed by the regenerator. The intercooling regenerative cycle combustion gas turbine system has the advantages that the afterburning combustion chamber is added between the high-pressure turbine and the low-pressure turbine, fuel gas flowing out of the high-pressure turbine is heated again, the temperature of an inlet of the low-pressure turbine can be increased, the temperature of tail gas recycled by the regenerator is high, and high-pressure air exhausted out of a high-pressure compressor is further heated. Circulation work of the combustion gas turbine is enlarged, the power is improved, and the heat efficiency keeps at a high level.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to an intercooling and heat recovery cycle gas turbine system. Background technique [0002] The intercooling and heat recovery cycle gas turbine is a complex cycle gas turbine composed of a compressed air intercooler and an exhaust gas regenerator on the basis of a simple cycle. Due to the addition of intermediate cooling and heat recovery processes, its efficiency is obtained compared with that of a simple cycle gas turbine. promote. [0003] Among the gas turbines, the gas turbine with intercooling and heat recovery cycle has attracted more and more attention because of its high cycle specific power and high efficiency. However, in conventional intercooling and heat recovery cycle gas turbines, the temperature of the gas drops after it expands through the high-pressure turbine to perform work. The exhaust gas discharged from the power turbine passes through the regenerator...
