Combustion oxidation

The vapor cloud of evaporated droplets bums like a diffusion flame in the turbulent state rather than as individual droplets. In the core of the spray, where droplets are evaporating, a rich mixture exists and soot formation occurs. Surrounding this core is a rich mixture zone where CO production is high and a flame front exists. Air entrainment completes the combustion, oxidizing CO to CO2 and burning the soot. Soot bumup releases radiant energy and controls flame emissivity. The relatively slow rate of soot burning compared with the rate of oxidation of CO and unbumed hydrocarbons leads to smoke formation. This model of a diffusion-controlled primary flame zone makes it possible to relate fuel chemistry to the behavior of fuels in combustors (7). [Pg.412]

Theoretically, to produce 1 kg of nitric acid requires at least 0.27 kg of ammonia and 4.33 kg of air (or 1.02 kg of oxygen). These weights refer to the content of concentrated acid. Realistically, however, the process is divided into three successive stages combustion, oxidation, and absorption. [Pg.88]

Combustion A chemical reaction caused by oxidation that produces light and heat. The production of light in the combustion process is the difference between oxidation and combustion Oxidation, regardless of slowness, will give off heat but no light will be produced. [Pg.227]

The most influential development of chemical theory of the eighteenth century was the phlogistic theory which attempted to explain and to correlate the phenomena of combustion, oxidation and reduction in a relatively simple and comprehensive maimer. The credit of founding this theory and of attracting the attention of chemists to it is due to Stahl. [Pg.425]

The number of ATP molecules one can generate by combusting any substance can be calculated, assuming that appropriate enzyme mechanisms are in place in the organism. Consider the combustion (oxidation) of a hypothetical substance... [Pg.25]

The higher the percentage of oxygen, or the higher the deposition temperature, the more complete is the combustion (oxidation) that occurs. The oxidant-to-fuel (solvent) ratio helps to control the flame temperature, size and velocity. Using pure oxygen versus air results in a more efficient and rapid combustion this in turn minimizes the formation of NO, carbon monoxide, and elemental carbon. [Pg.88]

Group 1 Relatively high benzaldehyde production and relatively low combustion oxides of tantalum, tungsten, zirconium and molybdenum. [Pg.544]

Group 2 Relatively high benzaldehyde production and relatively high combustion oxides of manganese, chromium, copper, nickel, thorium and uranium. [Pg.544]

Smelting was not the only transformation that ancient people tried to understand. Growth and decay, combustion, oxidization (or rusting), and fermentation were all significant transformations of one material into another. One of the most important transformations was the production of salt from brine, which produced a product so necessary to civilization that few of us would be here today if salt production had not been figured out. A large part of the history of science comes directly from efforts to make sense of these transformations and to determine what was the basic or purest elemental material. [Pg.199]
