The Scheme Design Of Power Plant Projects About Heating Network In Fulaerji

With China’s rapid economic development, development of industrial enterprises gradually expand the scale, but the people and improve the quality of life, so that the heating capacity of the existing heating network subject to certain restrictions, can not meet the actual demand. Thus, for power plant expansion project heating pipe network project has become an important research subject, we need to plan for timely adjustment according to the actual situation of each heating network and heating needs, design a more reasonable perfect heating power plant Reconstruction Plans pipe network project, to effectively improve the heating effect and improve the heating efficiency of great significance.In this paper, the research body Fulaerji thermal power plant, elaborate projects for its heating network expansion program. This works out to 2013 basic data as the basis for the design of the base year 2014, near to the end of 2016. The 2014 district heating project area 5,834,000 m2, central heating recent design area 7,545,900 m2(including Fufa manufacturers, genera and species 300,000 m2), long-term planning for the central heating area 8,525,900 m2. The project to change the way the direct heating indirect heating method, heating network first stop heating capacity and heating network backbone transmission capacity at the forward area of 8,525,900 m2 heating design, heat transfer stations and regional press recently heating area 754.59 million m2 design, recently involving a total of 20,780 m net new level, the maximum diameter of DN1000, direct supply pipe network transformation to become the status quo level pipe network 6256 meters, the new secondary network 13,085 meters, 29(including 13 new heat transfer station Block the new plant, the remaining old IDS), the new heating network intelligent control system.Based on the characteristics and status quo power plant heating pipe network, and propose two different expansion plan, conduct scenario analysis from the technical, energy and economic point of view, to determine the best programs in the renovation and expansion project, and the program framework of the program construction, construction and technical content specific programs Reconstruction Plans heating network design, renovation and expansion project on the basis of the analysis on the investment budget, the expected economic and social benefits evaluation projects after the reconstruction, proposed the implementation of renovation and expansion project safeguards program.From the point of view of energy saving, energy-saving effect of the project is obvious. Through the pipe network transformation and heat metering reform, improve heating efficiency, mobilize residents and enterprises to participate in energy-saving initiative, heating companies to reduce energy consumption and heat users save hot expenses, enormous direct and indirect energy savings, promote energy conservation in the region work in depth. From the perspective of environmental and social benefits of the project for the direct supply system to the system after room, boiler efficiency due to increased transport efficiency and pipe network, pipe network heat loss reduction 708006 GJ, commuted coal consumption decreased by 45,917 tons. Improve the heating quality and improve the living standards and quality of life for residents, while improving the purification of the urban environment, the construction of ecological zones will aim to have a positive and far-reaching impact; for investment, the development of local economy, have played an important role. Will make the overall environment Fularji District Qiqihar City to a new level, to the development of the city will bring more opportunities and conditions. Therefore, this study has important implications for Fulaerji power plant heating pipe network renovation and expansion project programs.
