Background technique
The gas compressor of existing gas turbine and turbine turbine are coaxial design, and the driving force of gas compressor is provided by turbine.Because the coaxial design of gas compressor and turbine, the operational efficiency of gas turbine is along with the variation fluctuation of load is larger; The efficient of gas compressor is lower under sub load, so that the gas turbine proficiency under the corresponding load also decreases.With the power equipment of existing gas turbine as regional generation, its part throttle characteristics has determined that its most of the time all will be in low operating mode operation.Because the gas compressor in gas turbine Study on Variable Condition Features changes greatly, has caused the performance driving economy of whole gas turbine very poor.
, be mainly used in ship power and have on the regional generation project of a large amount of water source areas because the consideration of economic serviceability for refrigeration technique between gas turbine, and generally do open cycle.A large amount of consumption of cooling medium and to the objective demand in place, refrigeration technique is at the broad development in gas turbine field between having limited; So that this achievement is being fired the practical application of mechanomotive force aspect is less always.
The thermodynamic cycle of gas turbine all is open cycle, and the high-temperature flue gas that produces after the turbine expansion acting directly enters in the atmosphere.Its high-temperature gas is larger to the contaminativity of environment on the one hand, and simultaneously, its a large amount of heat is also wasted along with discharging.Utilize in the industry at present the combined-cycle technology of fume afterheat comparatively ripe, but it need to increase outside a large amount of initial costs, the area requirements in place is also greatly improved.And this considers its cost and operational efficiency for load is not very large distributing-supplying-energy system, and its Economy also has the space of further raising.
Summary of the invention
The present invention is in order to solve the problem that cold using scope between existing electric generation gas turbine generator set is narrow, can't keep higher operational efficiency in wider load variations scope, simultaneously can low cost effectively utilize fume afterheat again, the invention provides a kind of cold main pipe type split gas compressor gas turbine group.
The technical solution used in the present invention is: a kind of cold main pipe type split gas compressor gas turbine group is characterized in that comprising two groups of above coaxial low pressure compressors and high-pressure compressor and firing chamber, turbine, cold female pipe, the female pipe of outlet and Absorption Refrigerator; Each low pressure compressor input shaft is connected with respectively the gas compressor motor by coupling; The air outlet slit of each low pressure compressor all is connected with the air inlet of cold female pipe, and the air outlet slit of cold female pipe is connected with the air inlet of high-pressure compressor respectively; The air outlet slit of high-pressure compressor is connected with the female pipe of outlet, and the female pipe of outlet air outlet slit is connected with the air inlet of firing chamber, and the outlet of firing chamber is connected with the fuel gas inlet of turbine, and the output shaft of turbine is connected with an end of electricity generating device by coupling; The smoke outlet of turbine is connected with the smoke inlet of Absorption Refrigerator, Absorption Refrigerator is provided with cooling medium entrance and cooling medium outlet, between cold female pipe be provided with the outlet of cooling medium entrance and cooling medium, the cooling medium outlet on the Absorption Refrigerator is connected with the cooling medium entrance on cold female pipe.
Cooling medium outlet on described cold female pipe is open with the cooling medium entrance on the Absorption Refrigerator, and cooling medium is open cycle.
Cooling medium outlet on described cold female pipe is connected with the cooling medium entrance on the Absorption Refrigerator, and cooling medium is closed cycle.
Be provided with the air channel that hot good conductor is made between the air inlet of described cold female pipe and air outlet slit, be provided with outside the air channel with a cold female pipe cooling medium entrance and be connected the housing that is connected with cooling medium.
The invention has the beneficial effects as follows: reduced the temperature of air between the high low pressure gas compressor by effectively utilizing the gas turbine fume afterheat, improved simultaneously its Economy and exerted oneself.By the structural design of split gas compressor, effectively improved the operational efficiency of gas turbine under low-load again.
Many all independently start and stop of coaxial high low pressure gas compressor of the present invention, the high efficiency of gas compressor in the time of can realizing low discharge (load), the energy that Absorption Refrigerator consumes is taken from the waste heat flue gas of gas turbine fully, has realized that effectively Economy and multifarious distributed energy use pursuit.The cooperation of Absorption Refrigerator and cold female pipe arranges, broken away from the past that the gas turbine inter cooler needs a large amount of demands of using cooling mediums, and cooling medium is closed cycle, has greatly improved the Economy of gas turbine installation circulation.
