Combustion organic materials

Organic Reactions. The chlorite ion, CIO,, is mosdy a weak and slow oxidizer in alkaline aqueous solutions. Aldehydes (qv) can be readily oxidized to the corresponding carboxyhc acids in neutral or weakly acidic solutions. Mixing sohd sodium chlorite with combustible organic materials can result in explosions and fire on shock, exposure to heat, or dames. 

Mixtures of the peroxide with combustible organic materials very readily ignite on friction or contact with moisture. 

Coals are sedimentary and sometimes metamorphic rocks that contain at least 50 wt % and 70 vol % combustible organic materials, which are often valuable sources of energy (Craig, Vaughan and Skinner, 2001), 503. Unlike many other sedimentary and metamorphic rocks, coals often contain substantial pyrite and other sulfide minerals. The organic matter and sulfide minerals in coals frequently have strong affinities for arsenic. 

Bituminous coal A sedimentary rock composed of at least 50wt% and 70 v% combustible organic materials that contains more moisture than anthracites, but less than subbituminous coals. 

Coal A sedimentary or metamorphic rock composed of at least 50 wt % and 70 v % combustible organic materials. In most cases, the organic carbon was derived from ancient terrestrial plants. Coals are potentially useful fuels (compare with lignite, subbituminous coal, bituminous coal, and anthracite). 

Hydrogen peroxide and peroxycarboxylic acids (RCO3H) are normally relatively stable, but as mentioned above they can be rendered unstable by a wide variety of contaminants, particularly at excessively high temperatures. Cleanliness, good housekeeping and proper storage are therefore essential. The major contaminants that cause decomposition are combustible organic materials (e.g. cotton, wool, paper) or metals, particularly transition metals and their salts (Table 1.7).50 Alcohol thermometers or stainless steel thermocouples... 

Tetranitromethane (TNM) is common byproduct resulting from the nitration of many organic substances. TNM is a toxic material. TNM is also an oxidizer that can form a powerful explosive when mixed with combustible organic materials such as benzene, nitrobenzene, toluene, etc. For example, the presence of TNM has been held responsible for explosions in trinitrotoluene (TNT) manufacturing facilities. Guggenheim 1996... 

Gases from the furnace are combustible organic materials which must be burned in... 

CALCIUM NITRITE (13780-06-8) A strong oxidizer. May become shock-sensitive from organic contamination. Violent reaction with reducing agents, combustibles, organic materials, ammonium salts, cyanides. Contact with acids forms toxic nitrous vapors. Rapid heating may cause explosion. 

PRIMROSE YELLOW (13530-65-9) An oxidizer reacts with reducing agents, combustibles, organic materials. 

It is the sodium-vanadium-sulphur reactions that will contribute substantially to the deposition problems in heavy fuel oil combustion. The vanadium in the fuel oil is generally associated with the combustible organic material so that, as the combustion process proceeds, the vanadium is subject to extremely high temperatures in the flame. Under these extreme conditions the vanadium will be converted to vanadium pentoxide At least some of the sodium present will... 

Ash leaving the combustion unit must be landfilled. If the ash contains high levels of metals, it may require treatment before disposal. The quantity of ash (as a percentage of the feed) varies but depends on the level of combustible organic material in the original waste. 

The total heat evolved from clay nanocomposites reveals little improvement once the reduction in combustible organic material due to the presence of silicate is accounted for. A reduction of about 1 to 3% compared to pure epoxy is observed by cone calorimetry. " This effect is far below that usually resulting from adding traditional flame retardants. For this reason, researchers turned...
