城市集中供热可以节约能源,方便群众,改善环境卫生,提高城市质量。中低压凝气式发电机组改为低真空运行,进行热电合产则是城市供热的有效途径之一。但是,电力部门、城市供热部门及用热单位在供热的盈亏问题上,看法不一。为促进热电合产集中供热事业的发展,本文从某发电厂实际操作数据出发,就循环水供热问题进行一下分析。 一、概况和运行数据 我国东北,冬季寒冷干燥,昼夜温差 Centralized urban heating can save energy, facilitate people, improve environmental hygiene, and improve urban quality. The low-pressure gas-condensation generator set was changed to a low-vacuum operation, and heat-electric cogeneration was one of the effective ways of urban heating. However, there are different views on the issue of the profit and loss of heating in the power sector, the urban heating sector and the heating units. In order to promote the development of the heating and heat concentrating district heating business, this article starts from the actual operation data of a power plant and analyzes the problem of circulating water heating. I. Overview and operational data Northeast China, winter cold and dry, day and night temperature difference
