太阳能集热与余热回收烤房的增温节能效果研究

摘要

为探索太阳能集热与余热回收烤房的增温节能效果，以气流上升式密集烤房为对照，对比研究了余热回收烤房、太阳能集热烤房以及太阳能集热+余热回收烤房3种改造烤房的增温能力、节能效果及烤后烟叶等级质量。结果表明：3种改造烤房集温室集热效果明显，表现为太阳能集热+余热回收烤房>太阳能集热烤房>余热回收烤房>对照；余热回收烤房、太阳能集热烤房以及太阳能集热+余热回收烤房的节煤率较对照分别提高了8.7%~10.9%、12.9%~16.5%、21.7%~21.8%；改造烤房对烤后烟叶等级质量影响较小。可见，太阳能集热+余热回收烤房的增温节能效果表现最佳。%In order to search out effects of heating and energy saving in bulk curing barns applied solar energy and waste heat recovery system,influence of the modified barns on heating and energy saving and appearance quality of flue-cured tobacco were investigated between various curing barns. Results showed that these modified barns(heat recovery(T1),solar energy(T2),combined of heat and solar power(T3)) had an obvious effect on heating and the increasing effects were T3>T2>T1;Compared with the control ( air rising bulk curing barn ) , the modified barns ( T1 , T2 and T3 ) saved 8 . 7%—10 . 9%, 12 . 9%—16 . 5% and 21 . 7%—21 . 8% of coals respectively;There was no significant effect on appearance quality of flue-cured tobacco. Therefore,the solar energy and heat recovery system of curing barn can increase the efficiency of energy using best.
