Comparative survey on central heating process for curing barns

In this paper, eight curing brans were taken as research objects, comparative survey on economics of heating technologies was carried out, which including traditional coal-fired decentralized heating, coal-fired steam boiler central heating, coal gasification central gas supply, thermal oil boiler central heating, biomass fluidized bed furnace central heating and biomass gasification central gas supply, in order to find the optimal heating process. Through comparison, the rate of energy utilization of traditional coal-fired decentralized heating is lower, which also causes serious environmental pollution, and its economic and social benefits are poor compared to other central heating processes. Generally considering the economic and social benefits, biomass fluidized bed furnace for tobacco stems burning central heating is the optimal heating process.
