Discussion on calculation method for actual smoke production

Fire smoke is a general term of gas and suspending granule in the scene of a fire, and it is the admixture of burning and decompound offspring. Smoke production lies on the combustibility of combustible substance and air-supply, etc. Fire smoke has the characteristic of oxygen deficit, poison, dust hazard and high temperature, with the addition of the light attenuation and funk of fire smoke, so fire smoke is the main cause of casualty in the scene of a fire, and the design of smoke prevention and discharge is very important in architecture fire safety. Actual smoke production calculation is the theory foundation in the design of smoke prevention and discharge. Some discussion was done in this thesis, aiming at the method of actual smoke production calculation in some documents. The authors put forward their calculation method, comparing the two calculation results and concluding that whether the air was superfluous must be considered in calculating actual smoke production.
