Study On The Scheme Design Of Heating Engineering Subject Construction And Comprehensive Benefit Evaluation In A Satellite City

With the development of economy, the continuous increase of population, thedemand for resources will continue to increase, China is a country of resources arerelatively deficient country, while urban heating and non renewable coal resources, sothe state through a variety of policies to encourage energy-saving emission reductionwork. In this environment, according to the requirements of thermal planning ofDalian City, combined with the actual situation of A satellite, the use of cogeneration,central heating to replace the decentralized heating boilers, is an important measure ofsaving energy and environment protection.This paper first through to the domestic and foreign cogeneration central heating,heating mode, this paper is divided into six chapters, the first chapter the researchbackground and the purpose of the conclusion is clear about this article, introducedthe domestic and foreign present research status and achievements of cogeneration;relevant theoretical basis of the second chapter elaborates the concept, principle andprogram design engineering construction scheme, and introduces the related theory ofcomprehensive benefit evaluation of the project, especially for the comprehensivebenefit evaluation method are introduced in detail; the third chapter A satellite cityheat supply engineering subject construction scheme selection part of the contentsinclude: Based on the A satellite city as the research object, introduces thebackground of the project, as well as the economic and geographical locationtechnical indicators, combined with the actual situation of A satellite city ofcentralized heating project, the main A satellite project options, options include:equipment and water plant site, these three aspects, the first on the options betweenthe analysis of the advantages and disadvantages, and then select one of the mostsuitable solution;. The fourth chapter establishes the evaluation index system ofcomprehensive benefits, including the principle of building index system, content,index to determine the right; comprehensive evaluation of three aspects of the fifth chapter of the economic benefits of the project, resource and environmental benefits,the comprehensive evaluation of the project and the conclusion, put forward in the lastpart of this chapter also pollution prevention and control measures; the sixth chapter isthe conclusion and prospect part, mainly analyzes the inadequacies of the study andresearch contents, brings forward the future prospects.In this paper, the centralized heat supply project main project A satellite city planis chosen, and the economic benefits of the project, environmental and resourcebenefits by fuzzy comprehensive evaluation, the A satellite city of central heating waycan effectively reduce carbon dioxide, sulfur dioxide and nitrogen oxide emissions he,is Protect environment, energy saving, improving the urban environment, animportant measure to improve the living standards of the people. I hope this researchcan provide some reference for the same type of project.
