Experimental Study on Biomass Heating System in the Greenhouse: A Case Study in Xiangtan, China
To meet the indoor heat load demand of greenhouses in China rural areas in winter, the authors proposed and designed a novel biomass heating system in greenhouses. The system uses biomass flue gas as the thermal working medium and heats the shallow soil inside the greenhouse through the buried flue gas-soil heat exchanger, thereby improving the indoor thermal environment of the greenhouse. To further study the heating system performance, we built up the heating experimental platform in a plastic greenhouse. Through testing the actual operation effect of the biomass heating system of the plastic greenhouse, no taking any heating measures system, the biomass heating system of the plastic greenhouse can improve the air average temperature and the soil average temperature 5.1 °C and 8.2 °C, respectively. The greenhouse biomass heating system is very economical, compared with the greenhouse without heating system, which can bring a 105% excess return rate for farmers every year. This study has obvious significance to promote the sustainable development of rural agriculture and the efficient utilization of rural biomass resources.
