Combustion Reactants, (4.31 × 32m), or (137.9m), grams of air. In some advanced applications to rocket propulsion, oxygen alone, or such alternatives as hydrogen peroxide, nitrogen oxides, nitric acid or fluorine, may be required as the oxidant, but the following treatment can be adapted for any oxidant provided its components, and their chemical behaviour, are known.Melodrama 发表于 2025-3-27 04:04:22
Introduction, engines. Once the components of a fuel are known quantitatively, straightforward calculation is possible of the stoichiometric mixture proportions (chemically balanced for complete reaction) with air or some other oxidant. Furthermore, if the resulting products are cooled, the proportions of stable出来 发表于 2025-3-27 06:20:13

Proportions of Hot Products,g rise to dissociation back towards the reactant forms of carbon monoxide and hydrogen, together with other species. At a given high temperature, a condition of dynamic equilibrium can be envisaged at which the rates of oxidation and dissociation are exactly equal so that the product composition rem观点 发表于 2025-3-27 22:09:10

Combustion Efficiencies,emical reaction energy is made available owing to imperfections of mixing, incomplete combustion by local chilling, unusable heat flow through the system boundary, and so on. Consequently, a parameter of combustion efficiency arises, of the following form . Should the actual mixture strength be stoiCROAK 发表于 2025-3-28 11:42:27
Oxidation in the Fuel Cell,ect conversion from chemical to electrical energy by means of the fuel cell. In contrast to primary and secondary cells, fuel and oxidant are supplied continuously during operation rather than being stored within the cell itself; consequently the electrodes are not consumed. Furthermore, the fuel an
