Description

Technical Field

[0001] The invention belongs to the technical field of combustion pools, and in particular relates to a novel combustion pool which is convenient for filling. Background Art

[0002] The biomass fuel used as the heat source comes from crop waste, forming a resource recycling lifestyle. However, in actual application, it was found that these traditional heating methods have low thermal energy utilization efficiency, poor heating effect, serious indoor pollution, and thermal comfort that does not meet requirements.

[0003] The technology of pool heating originated from the traditional method of using biomass energy for heating, and has been continuously developed and improved with the advancement of technology and the improvement of environmental awareness. The technical principle of pool heating is mainly to place the broken roots, stems, leaves, shells, sawdust, rice husks, reed flowers and other biomass fuels in the pool, and generate heat through smoldering (anaerobic combustion). This heat is transmitted through the heat dissipation surface through conduction, radiation, convection and other methods to increase the indoor temperature, thereby achieving the purpose of heating.

[0004] As a potential bioenergy utilization method for heating rural buildings, biomass smoldering can reduce the pollution caused by open burning of agricultural straw and meet the growing demand for heating in rural buildings. However, the biomass fuel used in the burning pool will still produce certain pollutants during the combustion process, so it is necessary to reduce the emission of harmful gases and improve indoor and outdoor air quality through reasonable design and control.
