Distributed heating/centralized monitoring mode of biomass briquette fuel in Chinese northern rural areas.

There are abundant crop straws in Chinese rural areas, but they are loose structure, low energy density and scattered distribution. Biomass densification technology is one of the effective ways to solve these problems. So the paper proposes a novel distributed heating/centralized monitoring mode of the biomass briquette fuel for rural areas. The mode includes the energy service station, the internet platform and the farmer households. A bidirectional C2S (Customer to Supplier) relationship between the energy service station and the farmer households is formed. The biomass briquette fuels are bartered using the crop straws instead of using money between the farmer households and the energy service station. The optimal service radius is calculated in different climate rons. The results are 4.75 km in extremely cold ron, 1.71 km in cold plain ron, 2.36 km in cold mountain ron. The use-scale of 1000 households is regarded as the standard for the promotion and application of the mode. The sensitivity analysis is that briquetting cost is the peak. At last, some suggestions are proposed, which will promote the future development of the briquette heating in China. • A mode of distributed heating/centralized monitoring is proposed in China. • A bidirectional C2S (Customer to Supplier) relationship is formed. • The optimal use-scale and optimal radius of the mode are calculated. • The "Internet + biomass energy network" is builds in rural area. • Some policies are suggested for the further development of biomass heating.
