In order to improve the heating efficiency and uniformity of the hot air circulation heater, a three-dimensional model of a hot blast stove of hot in-place recycling hot air circulating heater was established, based on the finite element method and CFD software ANSYS, the influence of the guide vane angle of the circulating hot blast stove sleeve on the temperature field and flow field of hot blast stove and air distribution pipe was studied by numerical simulation. The results show that the guide vane angle of the hot blast stove sleeve affects the temperature distribution at different positions of the air distribution pipe, has less influence on the internal temperature field of the hot blast stove, and has greater influence on the temperature distribution of the air distribution pipe. With the increase of the guide vane angle of the hot blast stove sleeve, the velocity and flow path of the circulating hot air in the hot blast stove sleeve increases, which improves the hot air distribution uniformity of the heating device. When the guide vane angle of hot blast stove sleeve is 45°, the hot air transverse distribution uniformity of heating device is the best.
