| 摘 要： | 机械化粮食烘干中采用生物质燃料替代常规能源，对节能减排、降低成本、提高粮食品质具有重要意义。设计了一套生物质颗粒热风炉并与谷物烘干机耦合，通过自动控温系统调节热风温度以获得高品质谷物。生物质颗粒在时间继电器控制下自动进料，在炉膛内部设计一次进风和二次进风口，颗粒燃料的挥发分充分燃烧，提高了热风炉的输出热功率。设置了故障报警、远程监控系统，提高了设备的智能化程度。性能试验结果表明，该成套设备运行稳定，性能指标优良，验证了设计的合理性。经济效益分析表明，利用生物质颗粒热风炉烘干谷物成本较低，具有明显的经济效益和推广应用前景。

| Abstract: | In grain drying with mechanical equipment, biomass is used to replace conventional energy fuel, which is of great significance for energy conservation, emission reduction, cost reduction and grain quality improvement．A set of biomass pellet hot blast furnace was designed and integrated with grain dryers．The hot blast temperature was adjusted by automatic temperature control system to obtain high-quality grain．Biomass pellet were automatically fed under control of time relay．Primary air inlet and secondary air inlet were distributed in the furnace．The volatiles of pellet fuel were fully burned, which improved output heat power of hot blast furnace．A fault alarm and remote monitoring system were set up to improve equipment intelligence．The performance test in the grain drying plant showed that complete set of equipment operated stably and had excellent performance indexes, which verified rationality of the design．Economic benefit analysis showed that cost of drying grain with biomass pellet hot blast furnace was low, which had obvious economic benefit and application prospect． |
