An energy saving project for the LNG-CCHP system in Xiamen natural gas power plant is put forward according to the basic data of this power plant.The system primary energy ratio,operation economics and energy saving potential are analyzed and calculated under some assumptions.The results show that the system total energy efficiency of this project is higher than 80%,with the energy efficiency of cooling-power system and heating-power system up to 89.2% and 82.8% respectively.Moreover,the operation costs for cooling system are fewer and the investment recovery period is less than 5 years.Therefore,the proposed LNG-CCHP system has great economic benefits and energy saving potentialities.
