摘要
为解决日光温室所使用的传统燃煤热风炉存在热效率低、燃烧不充分、环境污染、能源浪费等问题,研制了一种生物质热风炉,以废弃生物质秸秆为燃料,整体结构由储料系统、燃烧系统、热交换系统、烟道除尘系统及温控系统组成。在日光温室内使用生物质热风炉进行了各项试验,测试了其热工性能,并监测了生物质热风炉供热对日光温室热环境及作物生长参数的影响。试验结果表明:生物质热风炉换热量为6×10^(5)~8×10^(5)kJ/h,换热效率达到75%以上,较普通燃煤热风炉具有热效率高、燃烧充分、环保、节约能源等显著优势,有效提高了日光温室内空气温度、土壤温度及净光合速率,改善了温室内作物的生长发育,促进了作物果实产量及品质的提升。
In order to solve the problems of low thermal efficiency,insufficient combustion,environmental pollution,and energy waste in the traditional coal-fired hot blast stove used in the solar greenhouse,a biomass hot blast stove was developed,which uses waste biomass straw as fuel,and the overall structure is composed of storage materials System,combustion system,heat exchange system,flue dust removal system,temperature control system.Various experiments were carried out using the biomass hot blast stove in the solar greenhouse to test its thermal performance,and the influence of the heating of the biomass hot blast stove on the thermal environment and crop growth parameters of the solar greenhouse was monitored.The test results show that the heat exchange rate of the biomass hot blast stove is(6×10^(5)-8×10^(5))kJ/h,and the heat exchange efficiency is more than 75%.Compared with ordinary coal-fired hot blast stoves,it has higher thermal efficiency,full combustion,environmental protection and saving.Significant advantages such as energy have effectively increased the air temperature,soil temperature and net photosynthetic rate in the solar greenhouse,improved the growth and development of crops in the greenhouse,and promoted the improvement of crop fruit yield and quality.
