Abstract: In order to improve the used materials and design structure of the heat radiating system of the bulk curing barn, the low cost, convenient, durable refractory or ceramic fire tube heat dissipating system was used. The contrast test of the ceramic fire tube heat dissipating system to the steel-made heat system used in practice was completed. The results showed that the heating dehumidifying performance of the bulk curing barn by optimizing the heating system fan increased obviously, the heat exchange efficiency enhanced about 1%, the temperature rising speed enhanced 1.17℃/h and the proportion of mid high grade leaves,production value/ hm2 and average price of the flue-cured tobacco leaf respectively increased by 2.82%, 392.24 yuan and 1 yuan/kg, compared to the steel-made heat system used in practice. The inner quality and sensory smoking quality of flue-cured tobacco leaf were improved significantly.
