厦门东部燃气电厂LNG热电冷联产系统节能方案研究

结合厦门东部燃气电厂实际情况提出一种LNG热电冷联产节能方案.在一定假设条件下,分析了该方案下的系统能源利用率、运行经济性及节能潜力.分析结果表明:该节能方案冷电、热电系统能源利用率分别可达89.2%和82.8%,联产系统总能利用率超过80%,而且供冷系统的运行费用较低,投资回收期小于5年.

Analyses on energy saving project of a LNG-CCHP system in Xiamen eastern natural gas power plant

An energy saving project for the LNG-CCHP(liquefied natural gas-combined cooling heating and power) system in Xiamen eastern natural gas power plant is put forward according to the basic data of this power plant.The primary energy ratio,operation economics and energy-saving potential of the system are analyzed under some assumptions.The results show that 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 of cooling system are fewer and the investment recovery period is less than 5 years.
