摘 要

节能减排是我国经济和社会发展的一项长远战略方针, 也是一项极为紧迫的任务。回收余热降低能耗对我国实现节能减排、环保发展战略具有重要的现实意义。同时, 余热利用在对改善劳动条件、节约能源、增加生产、提高产品质量、降低生产成本等方面起着越来越大的作用, 有的已成为工业生产中不可分割的组成部分。

本文为工业应用方面的设计，主要设计一台余热回收锅炉，回收有排放的余热量以达到节能减排的目的。主要内容及设计流程如下：

设计余热锅炉时，除了整体布置外，首先必须进行热力计算。热力计算的任务是在给定的烟气及蒸汽参数下，确定锅炉各部件的尺寸及产汽量，选择辅助设备。热平衡计算前首先需要制作烟气的焓温表以方便计算时查找。再利用能量守恒原理计算得锅炉散热损失及工质蒸发量。紧接着便是过热器、蒸发器以及省煤器的结构热力结构计算。

Abstract

Energy saving and emission reduction is a long-term strategic policy of economic and social development in China,it is a very urgent task as well. Reducing the energy consumption of waste heat and reducing the energy consumption has important practical significance for our country to realize energy saving and emission reduction and environmental protection development strategy.. At the same time, waste heat utilization is used to improve working conditions, save energy, increase production, improve product quality, reduce the cost of production and playing a more and more important role. Some of them have become inseparable part of industrial production.

In this paper of the design of industrial applications, the main design is a waste heat recovery boilers, recycling the heat of the exhaust emissions of metallurgical sintering machine in order to achieve the purpose of energy saving. The main content and the design process are as follows:

When design the waste heat boiler, in addition to the overall layout, first you must make thermodynamic calculation. Thermodynamic calculation’s task is to determine the size of various parts of the boiler and steam production according to the given flue gas and steam parameters, and select the auxiliary equipment. Before the Thermal equilibrium calculation, the production of the enthalpy of the flue gas temperature table should be made in order to find out conveniently. Then, calculate the boiler heat loss and evaporation of refrigerant through the principle of conservation of energy. Last is the structural thermodynamic calculation of the super heater, evaporator and economizer.

Key Words: Waste heat recovery; Waste heat boiler; Evaporation; Super heater; Economizer
