| China has always put the protection of the environment and energy conservation as a basic national policy to build a resource-saving and environment-friendly country.The industrial upgrading strategy and green industry development path are implemented.Special emphasis is put on the research and application of environmental protection and energy saving technology for the industrial development with energy revolution as the forerunner.The main purpose is to achieve industrial manufacturing energy reduction,improve unit energy efficiency and reduce the atmospheric emissions of pollutants.Therefore,in order to improve the investment image and environment of Xi'an Fengjing Industrial Park,the scheme of building the centralized heating system with low-carbon environment and high economic benefits is decided.In order to select the best scheme of the centralized heating boiler system in Fengjing Industrial Park,this paper has carried on the following research:Firstly,the background of the centralized heating project construction and the policy environment of national development are analyzed in this paper.The domestic and abroad research status of the centralized heating system development,the centralized heating technology,the research progress of pulverized coal industrial boiler technology,the comparison of project selection method and the benefit evaluation of central heating project are introduced.Secondly,three project construction schedules such as the gas boiler system,circulating fluidized bed boiler system and high efficiency pulverized coal boiler system are developed.The experts score questionnaires are designed for three alternative schemes by the application of the Likert scale.According to the data of the survey results,the weight index of the boiler system of Fengjing Industrial Park is established,and the optimal scheme is determined.And then,the index weight regression analysis,environmental benefit and economic benefit analysis of the boiler system program are proposed.Finally,based on the investigation data processing combined with environmental benefits and economic benefitsanalysis,the efficient pulverized coal boiler system is determined as the optimal solution for centralized heating boiler system in Fengjing Industrial Park by the discussion and analysis of the results.The survey results show that the economic indicators and environmental indicators are higher than the technical indicators of centralized heating system for Fengjing Industrial Park.This result indicates that the economic and environmental benefits of implementation of centralized heating system project are fully considered.It is proved that the efficient pulverized coal boiler is an efficient and clean coal utilization technology by the research of the centralized heating system.The overall operation cost is low and the environmental protection efficiency and economic benefits are obvious.This research not only has the application value to promote,but also provide an idea for other centralized heating project.This study has a practical significance for the construction of centralized heating system in the region without cogeneration. |
