Heating furnace capable of forming circulating hot air on periphery

A heating furnace capable of forming circulating hot air on the periphery comprises a furnace body, a combustion chamber is arranged in the furnace body, a plurality of air pipes are arranged outside the furnace body, the lower ends of the air pipes are arranged at the lower end of the furnace body, and the upper ends of the air pipes are arranged at the upper end of the furnace body. The hot air circulation furnace has the advantages that relatively cold air at the lower end of the furnace body is sprayed out from the upper end of the furnace body through the air pipe after being heated by the air pipe under the condition that the upper end and the lower end of the furnace body have temperature, so that hot air circulation is realized. 一种能在周边形成循环热风的取暖炉，取暖炉包括炉体，在所述炉体内设燃烧室，所述的炉体外部设有多根风管，所述风管下端在所述炉体的下端，所述风管上端在所述炉体的上端。本实用新型的优点是，利用炉体上下二端存在温度的情况，通过风管实现炉体下端的相对冷的风经过风管加热后由炉体上端喷出，实现热风循环。
