In order to study the characteristics of heat flow field after fire in a narrow-long space, a mathematical and physical model for fire calculation in a narrow-long space is established. The control equations are simplified and deformed. The numerical program is used to solve the model. The characteristics of smoke spread, temperature field distribution and the change of fire parameters in different positions with time are obtained. The influence of ventilation on the heat flow field of fire is discussed. By analyzing the characteristics of fire flow field, it can provide reference for fire detection design in narrow-long space.
