| Abstract: | Considering that a hollow circular chimney composed of the multi-layers of fire-resistant, heat insulation and reinforced concrete and that low temperature chimney has short term super-high temperature phenomena, one-dimension transient physical model and mathematical model were established by using Laplace transform method, with formula of transient temperature concluded. Moreover, the theoretical formula were applied in combination of practical example, with the temperature distribution along the radial direction in a transient state proposed. |
