Technical And Economic Analysis And Evaluation Of Gas-fired Thermoelectric (cold) Co-ordination

Since the reform and opening up,China's economic construction and urban construction have developed rapidly.At the same time,the energy and environmental problems caused by the rapid development have also become more and more serious.In improving the urban environment,natural gas is based on high expectations due to its clean energy character.Since the 21 st century,with the development and utilization of natural gas resources and the adjustment of energy structure in our country,the dominance of coal and oil in energy has gradually been replaced by natural gas and has become the main body of urban consumption energy.Therefore,the application of natural gas in urban energy has become the people The important content of the research.In this paper,gas power generation system(cold)as the research object,first introduced the principle of thermoelectric(cold)generation system and several classical models,and introduces some basic principles of system configuration,by comparison to determine the system studied in this paper.Secondly,the load of the building served by the cogeneration system was calculated,and the annual dynamic load of different types of buildings was simulated by DeST energy consumption simulation software.The load characteristics were analyzed,and the thermal load was drawn based on the simulation results and load characteristics Continuation time chart.On the basis of a large number of investigations,the scale of heat supply is divided and two different system configuration schemes are formulated according to different heating scales.One is the heating system of pure boiler room and the other is the cogeneration Heating system.Finally,the economic evaluation of the two kinds of systems of different construction scale;by incremental method,system of different heating area,different configurations are compared,finally draws the conclusion of this thesis.This research has some practical significance for improving city environment,optimize the energy structure,but also for the thermal(cold)provides a theoretical basis for the reform and development of the city heating cogeneration system.
