Inerting agents

Other inert materials that can be used include water vapor and carbon dioxide, which are somewhat more effective than nitrogen because they have higher heat capacities. To use water vapor effectively as an inerting agent at atmospheric pressure, the temperature should be 90-95°C. Carbon dioxide is an effective inerting agent, but it has significant solubility in water and other materials and is reactive with alkaline substances. 

Mechanism of double membrane it can be used combined with detonation initiation and to study the evolution of flame which is caused by deflagration wave getting through inert agent, in order to learn about and evaluate the mechanism and effectiveness of fire retardant. 

The MOC determined in the laboratory at 850°C is a very safe value for most of the dryer applications in which the operating conditions are never as severe. Actually, the use of this value results in an nnnecessary high consumption of the inertizing agent. Hence, tests should be carried out at conditions that actually exist in the dryer. Some data on MOC are presented in Ref. [9].
