Heat and electricity cogeneration and concentrated heat supply can realize The project of has the synthetic of saving energy , environmental protection improving the quality of heating and increasing electricity servicing. It's one of the important measures for the city to deal with the air pollution and enhancing the energy's synthetic utilization ratio. And it's also the basal establishment of commonweal to improve citizen's living level, which just accords to our country's sustainable development strategy.This paper provides the analysis and study of economic operation of the heat power plant , which combines with problems indwelled in practical production. The followings are the main contents:1. Based on the investigation of the average heat load during heating period and non-heating period , the paper conducts the distribution of heat load ,thermodynamical calculation and economic index calculation for the union operation of various heating units.2. This article analyzes and studies the factors that affect the economic index of the heat power plant , and gives out the approaches and measures which achieve better benefit in practice.3. Through analyzing the present operation condition and heat supply respect of the Beihai Heat Power Plant which is the largest heat and electricity cogeneration and concentrated heat supply corporation in Dalian ,a scheme is settled to install a climax load adjustment boiler in the plant.4. The measures are handed out that optimize heat power plant economic index and the cost analyses, and the suggestions are put forward to improve the plant's management. |
