摘要：热力发电厂是一门政策性强、综合性强，与火电厂生产实际紧密联系的学问。通过对此课程的学习，培养学生树立安全和效益（经济效益、社会效益和环保效益）相统一的观点，以提高分析、研究、解决热力发电厂课程业务范围内生产实际问题的独立工作能力。
对于热力发电厂来说，为了达到节能减排的目的，我们必须提高热力发电厂的热经济效率。
本次设计的题目是CC100-8.83(90)/0.423/0.123型机组热电厂热力系统设计。在设计中，我们采用热电联产的方案，构建了一个热力发电厂热力系统。设计内容包括回热系统、辅助热力系统的拟定，原则性热力系统的计算，主、辅设备的选择，以及全面性热力系统的拟定，采用物质平衡和能量平衡的计算方法，通过五种方案的计算、比较、最终选择选择一个最佳的方案，提高热力发电厂的热经济效率。

Abstract：Thermal power plants is a discipline that with strong policy-oriented, high comprehensive, and is close contact with the actual production of the Thermal power plants. Through the study of this discipline, makes us establish a point of view that combining safety with benefit(economic benefits, social benefits, enviormental benefits), in order to improve the abilities to analysis, study, solve the actual production of the Thermal power plants.
For thermal power plants, in order to achieve the purpose of saving energy and protecting the enviornment, we must improve the efficiency of the thermal economy of the thermal power plants.
This design based on the CC100-8.83(90)/0.423/0.123 type turbine.In this design,we use the CHP program, providing a system of thermal electrical power plant which include the design of heat regenerative system and auxiliary heat systems, the calculation of principal thermodynamic systems, the select to major and auxiliary equipment, the design of plant integrity thermodynamic systems as well, uses the matter balance and the energy balance computational method. the best program was chose after counting and comparing the five different types of programs, in order to improve the efficiency of the thermal economy of the thermal power plants.
Key words：the thermal power plant；thermal dynamic system；thermal economic efficiency.
