To study the influence of such parameters as ammonia water concentration,CO2 concentration and temperature on the CO2 removal rate,an experimental study of ammonia water spray has been performed by employing a continuous on-line CO2 detection in a stepped-ring packed tower operating at different parameters with diluted ammonia water serving as an absorption agent.

According to the criterion,when the compartments catch fire,the mechanical exhaust can control the height of the smoke layer,and water spray can reduce the temperature of the smoke layer,if the fire protections are invalidated,the fire of compartments will be dangerous.

Smoke movement with water spray is studied by PHOENICS software.

The interaction between smoke movement and water spray is investigated by large eddy simulation (LES) approach.

By combining the determinate and stochastic methods, the concept of “equivalence”for fire safety strategy was used to study the probability distribution of real fire resistance level for building element under the action of sprinklers.
