The invention discloses an intermittent-cold back-heat main pipe type split compressor gas turbine unit which comprises more than two groups of coaxial low-pressure compressors and high-pressure compressors and a combustion chamber, a turbine, an intermittent-cold main pipe, an outlet main pipe and an absorption refrigerator, wherein an input shaft of each low-pressure compressor is connected with a compressor motor through a coupling; a smoke outlet of the turbine is connected with a smoke inlet of the outlet main pipe; a smoke outlet of the outlet main pipe is connected with a smoke inlet of the absorption refrigerator; and a cooling medium outlet in the absorption refrigerator is connected with a cooling medium inlet in the intermittent-cold main pipe. According to the invention, through effective utilization of the residual heat of the smoke of the gas turbine, the front air temperature of the combustion chamber is increased; the temperature between the high-pressure and low-pressure compressors is increased through absorption refrigeration; and through the split compressor, high efficiency of the compressor under low load is realized, and the economy and power output are improved.
Description
technical field [0001] The invention relates to a gas turbine set for power generation, in particular to an intercooling heat recovery main pipe type split compressor gas turbine set, which is a gas turbine set for distributed energy applications. Background technique [0002] The compressor and the turbine of the existing gas turbine are of coaxial design, and the driving force of the compressor is provided by the turbine. Due to the coaxial design of the compressor and the turbine, the operating efficiency of the gas turbine fluctuates greatly with the change of the load; the efficiency of the compressor is low under partial load, so that the efficiency of the gas turbine under the corresponding load also decreases. Taking the existing gas turbine as the power equipment for regional power generation, its load characteristics determine that it will operate under low working conditions most of the time. Due to the large change in the characteristics of the variable operatin...
