摘要

根据热水二段型溴化锂吸收式制冷机的性能参数和太原市城区集中供热系统的参数

计算分析了300MW抽汽-凝汽式机组采用冷电联产的热经济性。计算结果表明

在溴化锂吸收式制冷机的热力系数不低于0.825、电网的供电煤耗率不低于0.388kg/(kW·h)、线损率不低于6.98%、电动式制冷机的制冷系数不高于3.5时

300MW抽汽-凝汽式机组采用冷电联产节能效果显著。

Abstract

Based on characteristic parameters of the hot water two-section type lithium bromide absorbing refrigeration machine and the parameters of the central heating system in Taiyuan City proper

the thermal economic behavior of adopting cool-electricity cogeneration to 300 MW extraction condensing unit has been calculated and analysed. The results of calculation show that the energy-saving effect to be remarkabe if the thermal coefficient of lithium bromide absorbing refrigeration machine isn’t less than 0.825

the coal consumption rate of power supply in the gride isn’t less than 0.388 kg/kWh

the line loss rate isn’t lower than 6.98%

and the refrigeration coefficient of electric motor driven refrigeration machine isn’t higher than 3.5.
