Research On The Technical And Economic Problems Of Circulating Water Surplus Heat Utilization Project Of Combined Gas-Steam Cycle Unit

Environmental pollution has become the primary social problem of our country and the world have to face,and pollution is the core of energy saving and emission reduction,as power companies to develop energy conservation as a top priority,China's relevant departments now also proposed stricter energy saving and emission reduction requirements of electric power enterprises,which needs electricity to keep exploring new technologies,new measures to enhance their energy efficiency and reduce emissions.Paper aimed at described for reduced power plant of energy,on existing 2x254MW gas-steam joint cycle heating unit proposed a based on using bromide of lithium absorption type hot pump circulating water waste Heat utilization,the technology extraction generator group of cycle water heat for city heating,in thermal power plant within set bromide of lithium absorption heat pump station,using unit cycle cooling water as hot pump of heat water,extraction heat heating hot network water,to significantly upgrade thermal power plant of heating capacity and the efficiency,further reduced integrated power energy,Purpose of achieving energy saving and emission reduction.There are a lot of low temperature circulating water in power plant thermal energy,heat pump with the low temperature heat energy into heat energy.This articles through on application user of hot load analysis to argument project construction of need,while on absorption type hot pump this a core technology of principle and the application for described,on existing 2x254MW gas-steam joint cycle heating unit using hot pump recycling power plant cycle water heat technology,from unit of cycle water,and electrical,and hot workers control,system for technology angle of feasibility analysis,on project of installation and commissioning do detailed description,developed effective of technology measures and operation,Also pointed out that the main circulation water waste heat utilization project lessons and insufficient reasons for the deviation of the main indicators,describes the major advantages and disadvantages of project management,and technology.Through the comparison process indicators proved that waste heat recovery of circulating water in the 2x254MW of gas-steam combined cycle thermal power unit with good technical,economic and social benefits.
