燃煤电厂热耗研究分析与优化

Analysis and Optimization of Heat Consumption in Coal-fired Power Plant

燃煤电厂中,热力系统设备的完善程度,热经济性的好坏,通常用热经济指标来表征。常用的热经济指标包括以下几种:全厂热耗、全厂热效率、发电煤耗和供电煤耗。文章通过对燃煤电厂热耗的计算公式进行研究分析,找出燃煤电厂与热耗的相关技术经济指标。针对性的采取优化方案,提高燃煤电厂热耗指标。

In coal-fired power plants,perfection degree of thermal system equipment and quality of thermal economy are usually characterized by thermal economic indicators.Commonly used thermal economic indicators include the following:heat consumption,thermal efficiency of the whole plant,coal consumption for power generation and coal consumption for power supply.This paper studies and analyzes calculation formula of heat consumption in coal-fired power plants and finds out relevant technical and economic indicators of heat consumption in coal-fired power plants.The optimization scheme is adopted to improve the heat consumption index of coal-fired power plant.
