330 MW冷热电联产机组热经济性分析
Thermal economic analysis of a 330 MW extraction-condensing steam unit
摘要
Abstract
Heating load of a thermal power plant is used for industrial extraction steam heating and civil heat supply.During the non-heating season,the heating load of thermal power plant reduces,resulting in an in-crease in unit coal consumption and waste of civil heating network.Therefore,the original heat and power cogeneration unit was transformed into combined cooling heating and power (CCHP)unit.Calculation after the retrofitting shows that:energy-saving benefit of the CCHP unit was obvious when the electric refriger-ator refrigeration coefficient was less than 3.5;while thermal economy of the CCHP unit under low thermal electricity ratio decreased when the electric refrigerator refrigeration coefficient was larger than 4.So,ways of improving the thermal coefficient of lithium bromide-water refrigerator,reducing industrial extraction steam load and increasing cooling load were suggested to be adopted to improve the economic benefits of the CCHP system.关键词
