Abstract In order to get the method to inhibit the destruction of inwall，the effects of temperature field，amount of coke and the triangle wall on the deformation of internal wall of annular air duct were studied by the coupled method of thermal stress and structural stress in 260 t/h large CDQ. It was found that due to the effect of the temperature field，the deformation of the internal wall increased more remarkably than that in the cold condition. It is indicated that the thermal stress is major factor on the internal wall deformation. Under the cold or hot conditions，the deformation of the internal wall of the annular air duct will be enlarged with the increase in the quantity of coke in CDQ. The triangular wall can inhibit the deformation of the internal wall obviously. When the temperature field is applied，the deformation of the internal wall was alleviated when the quantity of coke reaches 4 meters more or less. The most reasonable height of the triangular stand wall is 1.0 meters.
