Typical space fire simulation analysis and engineering practice of underground sewage treatment plants

The FDS (fire dynamic simulation) numerical simulation software is used to simulate the fire in the typical areas (large spaces and cross corridors) of underground sewage treatment plants. By setting the fire source of different fire power in different locations, the change of flue gas temperature, flue gas movement, flue gas concentration, visibility and other factors with time is studied. The impact of fire on personnel escape under different working conditions is analysed, which provides a basis for the fire protection design of typical space of underground sewage treatment plants.
