| The haze weather occurred frequently in our country in the winter,which has influenced the production and life seriously.An important direction of the prevention and control of atmospheric pollution is the optimization of the energy structure adjustment,and the "coal to gas" is one of the important measures of energy structure adjustment.Many cities have imposed "coal to gas" in the process of adjustment of energy structure in order to control the fog haze weather.This article mainly analyzes the characteristics of the gas heating and how to effectively guarantee the feasibility and reliability of the gas heating.First of all,it expounds the important ways of natural gas for heating briefly and analyzes the principle of work,for coal and applicable occasions.Then calculates their smoke gas in detail according to the burning of coal and gas empirical formula calculation and compares their emissions according to the emission standard.Then calculates reduced emissions of pollutants of a heating season after natural gas instead of coal and the corresponding environmental pollution treatment costs,and analyzes of the environmental benefits of natural gas,the results show that the natural gas has remarkable environmental benefits.Due to the coal is higher,analyzes the withstanding capability of the heating companies after they choose natural gas,and then discusses the method of improving the heating enterprise to bear ability separately from the sale price of heating and building energy saving coefficient.To increase the sale price of heating and building energy saving coefficient is the appropriate method of improving the heating capacity of the enterprise.Due to the "coal to gas" project in the northern part of the city,selects several kinds of commonly used gas heating way,analyzes and compares the heating costs to choose the appropriate ways,household gas heating is more economical.Town pipeline supply system is the main way of natural gas supply,natural gas demand is growing with the expanding of the application of natural gas.To analyzes and calculates of natural gas high-pressure pipeline capacity,and the flow calculating congestion phenomenon when the maximum velocity of natural gas,pipeline capacity and various parameter values.Then analyzes the parameters of flow in the pipeline and analyzes the existing problems in the calculation of gas flow.And analyzes the relevant parameters affecting the pipeline capacity,discusses the effective ways to improve the ability of gas transmission pipeline.Heating gas load is the seasonal load,the gas as the outdoor air temperature change and constantly changing.In order to ensure the reliability of natural gas heating,discusses the heating seasonal peak shaving of gas storage way.Taking Ji-nan as an example,calculates the heating gas demand,chooses peak shaving gas storage way,calculates the load of gas storage.In this paper,through analyzing the choice of the ways of gas heating and the analysis of its environmental benefits,can provide certain theoretical basis for the implementation of "coal to gas" project.It can also provide some suggestions for the reliability of natural gas heating. |
