Considering the question of high initial investment and high energy costs for air-source heat pump barn and biomass briquette fuel barn and the question of high energy consumption and obvious environmental pollution from forward combustion for metal furnace and tunnel furnace,a kind of clean-coal reverse-combustion hot-blast furnace with the uniform flow of all combustion air through the coal bed and with the center ignition using the burning bituminous coal from the coal-bed top has been developed. The anti-burning furnace includes a barrel-shaped chamber with 1.5m in height and 0.9~1.1m in diameter,the operating mouth with 0.56m in width and 1.5m in height is opened in the side wall of chamber,the chamber is connected with the operation passage through the operation hole,the operation hole under the bars is the ash hole,the ash hole is blocked by the inner furnace door,and the right port of the operation hole is sealed with the outer furnace door. About 950 honeycomb briquettes can be loaded into the chamber of the anti-burning furnace one-time previously,the accurate control on its combus-tion and heat can be realized at the low cost,and there is no burning accident of the combustion fan. The feasibility supporting the intensive flue-cured tobacco has been proved by baking tests for 30 furnace times in 2016-2017. A new plan is provided for the update of the three-high coal-fired hot-blast furnace.%针对空气能热泵烤房和生物质成型燃料烤房初始投资高和烘烤能源成本高,金属炉和隧道炉正向燃烧能耗高和污染环境等问题,研发一种全部助燃空气均匀流过煤床且煤床顶面中心烟煤点火的洁净煤反向燃烧热风炉.反烧炉包括H 1.5m×Φ(0.9~1.1m)且呈桶状炉腹,炉腹侧壁开设W 0.56m×H1.5m操作口,通过操作口炉腹内腔和操作通道连通,炉条以下操作口为清灰口,清灰口用内炉门堵塞,操作通道右端口用外炉门密封,一次性预装约950个蜂窝煤球,能低成本地实现精准烘烤燃烧供热,无助燃风机烧损事故.2016—2017年30炉次烘烤试验证实反烧炉配套密集烘烤使用可行性.为"三高"燃煤热风炉更新提供新方案.
