An anti burning hot stove with a ribbed clean coal, including a combustor, a rib, a smoke exhaust pipe and a briquette, is arranged vertically and the outer wall is fully welded together with a large number of rectangular fins. The transverse edge of the bottom of the fin is connected to the outer wall of the top of the combustion chamber, and the radius of the chamber is 1.0m to 1.2m, through the chamber and row of the combustor chamber at the top of the combustor. The internal cavity space of the smoke pipe is connected with the briquette bed, and the briquette bed is circular columnar. There is no obvious gap between the adjacent two types of coal. The ring top surface of the briquette is close to the inner wall of the combustion chamber. The inner diameter of the briquette is 200mm to 300mm, and the inner wall of the briquette is facing the lower extension surface of the inner wall of the exhaust pipe, the outer side and the wall of the combustion chamber. From 100mm to 150mm, the inner side space of the briquette bed is the ignition area. The invention can be used for hot flue stove with dense flue-cured tobacco and loose leaf flue-cured tobacco. The invention has one-time coal loading and coal saving 25%, which can closely match the technological curve to generate hot air and assist the fan temperature.

带肋片洁净煤反烧热风炉
本专利技术涉及一种具有明火反烧、高温隔离、助燃风机启停精准调控燃烧供热等技术特征的带肋片洁净煤反烧热风炉,适用于农业农村领域密集烤烟和散叶烤烟热风室燃烧供热装置使用。
技术介绍
随着我国烟农户均种植烤烟规模的增大和现代烟草农业的发展,密集烘烤在全国范围内得到了快速推广应用。以2012年为例,全国建有密集烤烟房约120万座。据统计,越来越多密集烤烟房采用基于暗火正烧原理的隧道炉燃烧供热。隧道热风炉结构简单、成本低,能一次性装煤,即一次性装入800~1000个圆柱型煤,能满足5~6天烘烤供热需要,不影响烟农夜间休息,特别满足当前各烟区雇工难且劳动力成本高等形势需要。隧道炉炉内腔包括顶部拱顶区和底部长方体区,拱顶区底面和长方体区顶面重合,长方体区包括靠近左端墙的长方体状引燃区和靠近右端墙的长方体状型煤床区,煤床区叠满圆柱型煤,引燃区堆放引火燃料,引燃区和拱顶区相连通。隧道炉以暗火正烧方式燃烧供热。调查显示:燃烧区紧邻助燃风机,高温炉气反向倒流至助燃风机壳体内,导致助燃风机高温损毁率高达39%。实践表明:助燃风机线圈绝缘性能下降导致出风能力永久性下 ...
