Urban Heating Network Heat Load Analysis And Optimization

Nowadays,the heating network is developing rapidly with the progress of urbanization in China.After a long period of development of heating networks in European countries,driven by various regulations and policies,the Europeans already have mature technologies in the planning and design of heating networks.Through a high-quality urban heating network,energy efficiency can be improved,pollution emissions from heating can be reduced,which can promote the transformation of the energy structure,increase the proportion of renewable and recycled energy,and reduce the use of fossil fuels.This article will proceed from the planning and design of the heating network in Nevers,France,and analyze the heat source design,construction cost,and optimal design of the network.The content of the article is as follows:1.Through the analysis of the current heating situation in Nevers,analyze the possibility of developing a new heating network.By putting forward the selection criteria for the heating area,analyze the factors which can affect the design of the heating network in Nevers.2.Combining the two heat load calculation methods,planning,and designing a potential heating area in Nevers City.Three 8MW biomass boilers and one 6MW gas boiler to warm up the new area.It is expected to be the area that provides a heating capacity of 28.8MW.3.Combining the hydraulic calculation and heat desperation model of the heating networks,a cost model of the heating network is proposed.The efficiency indicators of the heating network are evaluated from the aspects of the construction,operation costs and heat desperation costs.Various heating planning to verify and compare the cost model of the heating network.4.Analyze the advantages and disadvantages of heating network,compare with the cost of the gas boiler.Calculate the factors such as the construction and operation costs of the heating network,and analyze the benefit of the urban heating networkThe newly heating network may contribute to the multi-heating source heating network and improve the efficiency of the operation of the heating network.Promote the role.It also provides a guarantee of the daily heating of the residents of Nevers.
