The Research Of Distributed Heating /Centralized Monitoring Mode Based On Biomass Briquettes

The study of clean heating mode in rural areas of northern China have been the urgent affairs for researchers under the background of the “coal forbidden” for atmospheric controlling.This paper suggests that using biomass briquettes for winter heating is one of the feasible way after the study on the energy consumption of rural buildings,and the energy alternative policies implemented by the government.In order to get a win-win mode,the author made a systematic analysis of the current situation and existing problems of biomass utilization in rural areas,processing technology of briquetting fuel,combustion technology,production technology of biomass stoves as well as the development situation of biomass fuel supply chain.The result concludes that only with the problem of high fuel costs,intensive manual labor and poor farmers' enthusiasm solved can the mode be promoted.This article proposes a distributed heating/centralized monitoring mode on the basis of the biomass briquettes for rural household in northern China which follows the principle of circular economy and takes the value of the straw,the interests of peasants,local government,as well as investors into thorough consideration.This mode,which adhere to the principle of "barter",build a bidirectional C2 S relationship between service provider and farmers.There is no clear distinguish between the supplier and demander,they both play the two roles,and realize the equal exchange of straw.Simultaneously,service platform is built based on the information and communication technology in the heating area which will benefit all the users and the company.Service provider can monitor the heating situation and study farmers' energy use habits through the platform and farmers can also share the information of surplus straw.With the help of the internet,there form an "Internet + biomass energy network" in the area and realize the share of the straw resource.Based on the mode,a further study on the optimal radius of service was carried out with the practice running data of the biomass boiler designed by the group independently in different regions with different scale of northern China.The results show that the most suitable promotion scale is that each service station serve 1000 households.In addition,the optimal service radius exists difference due to the different biomass yield in each region.Under the condition of hypothesis,the optimal radius of the service area is 2.27 km,with the lowest fuel cost of 113.86 RMB/t in Zunhua,Hebei province.In relation to the area with excessive biomass,the cities in northeast China for instance,to avoid resource wasting,it will be better to promote a joint way of different energy-oriented use mode.
