In recent years,north China has been frequently affected by haze weather,with serious air pollution and PM2.5 monitoring concentration reaching new highs.Although Beijing has adopted measures such as"clean air action"and"coal to gas"and"coal to electricity"over the years to reduce the total amount of coal burning,the situation of haze pollution is still very serious and the prevention and control task is still very difficult.The clean air action of reducing and exchanging coal for coal in rural areas of Beijing is an important measure taken by the CPC central committee and the state council to prevent and control air pollution in the capital.The urban and rural areas and rural areas"coal reduction for coal"and clean energy heating are the main tasks of the 13th five-year plan of action on clean air.In this study,the feasibility of data collection and the differences between different regions are fully considered.A total of 2404 villages that have completed the work of"rural coal to gas"are selected as samples in plain area and shallow mountain area respectively,and literature collection method,theoretical analysis method,field investigation method,statistical analysis method are used for research.By sorting out,analyzing and calculating the survey data,the gas consumption index of rural wall hanging furnace users in Yanqing District is 10.8m~3/m~2·a,that of rural wall hanging furnace users in Changping District is 9.87 m~3/m~2·a,and that of rural wall hanging furnace users in Daxing District is 7.98 m~3/m~2·a.the calculated gas consumption index is related to the living habits,living time,economic conditions and other factors of rural residents It can reflect the facts objectively.Therefore,in the design of rural coal to gas,we should take full account of all factors.The monthly peak coefficient of rural wall mounted furnace users is greatly affected by the climate temperature.The monthly peak coefficient of Yanqing District is 3.089,and that of Changping District and Daxing District is 3.221.The daily peak coefficient of rural wall mounted furnace users is greatly affected by climate temperature,holidays and working rules.The daily peak coefficient of Yanqing District is 1.169,and that of Changping District and Daxing District is 1.123.The hourly peak coefficient of rural wall mounted furnace users is greatly affected by economic conditions,living habits,working rules,etc.,with 1.083in Yanqing District and 1.137 in Changping District and Daxing District.In this study,two groups of simultaneous working coefficient values of Yanqing District and Daxing Changping District are obtained.Compared with the current specifications of urban residential users,the simultaneous working coefficient of gas appliances obtained by the study is smaller than the current standards of urban residential users.
