Factors affecting the burning process

First, the rate of heat production is again related to the sum of the rates of depositional and burning processes, and if the predominant factor affecting the overall rate is temperature, then it does not seem likely that the specific effect of water vapor on the oxidation reported here is chemical catalysis, since a lowering of activation energy for either process would result in an increase in the overall rate relative to dry oxidation. 

The theory of premixed flames essentially consists of an analysis of factors such as mass diffusion, heat diffusion, and the reaction mechanisms as they affect the rate of homogeneous reactions taking place. Inasmuch as the primary mixing processes of fuel and oxidizer appear to dominate the burning processes in diffusion flames, the theories emphasize the rates of mixing (diffusion) in deriving the characteristics of such flames. 

Propellants are explosive materials with low rates of combustion diat will ideally burn at uniform rates after ignition without requiring interaction with the atmosphere [1,2], They frequently involve several components, including an energetic oxidizer, a plasticizer to facilitate processing, and a polymeric binder. The specific impulse of such propellants is necessarily that of the composite mixture. Oui focus here is on chemical and structural factors affecting the specific impulse of the oxidizer, which will be designated as a monopropellant. 

The start of every selection process should be an identification of the hazardous chemicals and an exposure risk analysis. The risk analysis may identify other methods of mitigation potential exposure that may reduce or eliminate the need to rely on CPC. You should assess exposure from skin absorption and skin effect from burns, sensitization, and/or other chemical hazards. Assessments should also consider biological, heat, fire, and mechanical hazards that may factor into the selection of CPC. Also, the hazards presented by CPC should be considered. CPC may contribute to heat stress, reduced mobility, obscured vision, difficulty in communication, lessened hand function (dexterity, grip, tactility), poor comfort, and skin illnesses. CPC may also affect the efficacy of other PPE worn, for example, ear muffs and respirators. Also, the other potential hazards (e.g., heat and flame) should be identified in the early stage of selection.
