研制了一种新型燃煤热风炉。它采用了当今高效传热技术——热管，积木组合式结构及强化燃烧、强化传热和热补偿等措施。理论与实验表明，它具有热效率高、寿命长、煤种适应性强、劳动强度小和污染小等优点。这种新炉型可较好地用于粮食和其他农副产品的干燥过程 Developed a new type of coal-fired stove. It uses today’s efficient heat transfer technology - heat pipes, modular building blocks and enhanced combustion, enhanced heat transfer and thermal compensation and other measures. Theoretical and experimental results show that it has the advantages of high thermal efficiency, long life, adaptability of coal, small labor intensity and small pollution. This new type of furnace can be better used for the drying of food and other agricultural products
