| Energy is one of the key elements for human survival, also is a basic development for a country, taking no energy any modern civilization will be mentioned. As a national economic and social development of the important strategic materials, energy is the basic support of the national economy. The harmonious of development of3Es (economy, energy and the environment harmonious development), realizes the great-leap-forward development of China. The wide use of fossil fuel causes the continuous increasing concentrate of CO2, resulting in a global temperature increase and the worldw attention to the global climate change.Heating area in winter in the northern in China is huge, heating consumption of energy accounts for a large proportion of the total energy consumption of the whole society, in particular, China’s primary energy consumption structure of coal, the main features of urban air pollution, smoke pollution, coal and other fossil fuel use, making the citythe environment is very much affected, seriously hampered the sustainable development of cities.Urban heating system is the research object in the paper, and shenyang is the research background, combining with the thermodynamic analysis method, the scene analysis method such as the qualitative and quantitative research from the multiple urban heating system in carbon emissions.Paper reviews the development courses of the the city heating firstly, then introduces the heating business change of Shenyang city and describes the various parts of the composition of the heating system energy consumption situation exactly, drawing a base flow diagram of shenyang through the energy flow analysis, preparing the energy balance sheet of shenyang in2005and2006, based on the energy balance sheet data, drawing the heat and power production sector energy flow diagram in2005and2006of Shenyang, ascertaining the situation of the overall energy use and conversion, analyzing the impact of heat and power production sector of the city’s overall carbon emissions and energy consumption through the whole city’s energy flow.For urban heating system, providing the heat to the hot users is not create carbon emissions directly, in energy conversion system input energy to locate the carbon emissions is city heating system carbon emissions, such, heating system of carbon emissions is actually the power level and the system energy consumption directly linked together. From thermodynamics nature will be heating system into two categories, the use of exergy analysis method to calculate the belong to the two types of system, four types of typical heating form of energy efficiency. The flow analysis can flow graph to draw the Shenyang, based on the energy balance sheet data to draw the Shenyang power production department to heat and flow chart, through the whole city and the department of energy to flow, heat and power find the production department of urban overall carbon emissions and energy consumption influence.Energy conversion system by carbon emissions to locate a energy input structure and quantity decision, in the quantitative evaluation of urban heating system level of carbon emissions should be taken into consideration when energy products to the special properties, that end users consume energy product quantity and quality. Used carbon emissions index of the unit energy products and the exergy analysis methods to evaluate the different heating mode of carbon emission status, the carbon emissions index is divided into two parts minimum emissions and additional emissions. Carbon emissions index of water source heat pump (WSHP) and Carbon emissions index of combined heat and power (CHP) conducted a comparative study.In2009China’s carbon emissions targets released, according to the Chinese government put forward a carbon emissions targets to Shenyang heating system as the research object, through the scene analysis method, this paper discusses2013to2020Shenyang heating system carbon emissions. The thesis research technical route for urban heating system the influence factors of carbon emissions, the construction of the scene analysis model, scene set in the scenario analysis result quantification discussion. The total heating area forecast model are established and the scenario analysis model are analysed. Through the reasonable setting, with the aid of urban heating system model tool in social macroeconomic factors, future energy technology progress, related field development, the technology department policy, equipment structure, heat source conversion efficiency, the future social demand for energy, may the development status of the simulated calculation, Urban heating system to realize the carbon emissions cut way and finally can achieve emissions reduction degree of objective and deep analysis. |
