摘要：随着中国各个城市人口和各类产业的快速发展，城市面积和城市空间的迅速增长导致城市面积和空间的迅速增长，导致城市生活垃圾总量的急剧增长，对城市造成了很大影响，危害了城市环境和人民的健康，妥善处理产生的垃圾越来越成为城市可持续发展必须解决的问题之一。因此，城市需要有一种可以减量化、无害化处理垃圾的方法替代这种简易的填埋。采用建造大型垃圾焚烧锅炉处理生活垃圾，对垃圾进行焚烧，一方面，可以大量减少了垃圾填埋，节约土地资源；另一方面，利用了垃圾固有的热值发电，使之变废为宝、节约资源。根据余热回收加热给水产生蒸汽的原理，设计一套余热利用锅炉的汽水系统，产生满足要求的蒸汽；尽量降低排烟温度；设备布置合理，装置效率达到最佳。

Design of Waste Incinerator Steam Water System

Abstract: Along with the city developing rapidly, the urban population and each industry fast development, the urban space development, at the same time the total urban living garbage rapid growth, has a harmful effect on urban environment and people's physical health, garbage properly handle more and more become one of the city sustainable development must solve the problem. The past garbage disposal are mainly composed of the landfill, landfill is difficult to meet the requirements of environmental protection of health, both "fight" with people, and cause pollution to the surrounding nvironment. Therefore, cities need to have a method of reduction and disposal of waste to replace the simple landfill. With large processing waste, waste incineration boiler of garbage incineration power generation, on the one hand, the use of waste calorific value of the inherent power, make it waste and conserve resources; On the other hand, a large number of reduced garbage landfill, save the land resources. So  the  garbage  power  generation  technology  is  a  green  environmental protection industry has a huge potential can be dug. In order to reduce the waste incineration high exhaust temperature of the problem of energy efficiency is not high, design a set of garbage incinerator system, recycling waste incineration flue gas waste heat, to achieve energy conservation and emissions reduction. According to the principle of waste heat recovery heat water to produce steam, design a set of waste heat using the boiler system, meet the requirements of steam produced; As far as possible to reduce exhaust smoke temperature; The best equipment layout is reasonable, the device efficiency.
