combustion coal and pollution

Coal is mainly elemental carbon with small amounts of hydrogen, oxygen, sulphur and nitrogen. On complete combustion of coal, carbon dioxide is the main product formed. This is non-toxic, but contributes to the green house effect if produced in excess. Small amounts o..

Combustion means the burning of a substance. It is a process that is highly exothermic i.e., produces a lot of heat. The products of combustion of carbon and its compounds are heat energy, carbon dioxide and water (vapour). In order that a fuel undergoes combustion, t..

Combustion - The burning of a substance is called combustion. It is an exothermic process (chemical reactions which give out heat to the surroundings are called exothermic reactions). E.g., Burning of coal Burning of butane gas (g - gas form) The common observation in ..

Combustion is a chemical reaction in which burning of substances takes place. In this process, a substance combines with oxygen to burn (decompose) itself liberating heat and sometimes light and flame. Thus, combustion reactions are exothermic or heat dissipating reactions..

. to reduce the dependence on hydrocarbon fuels. A related aspect of management of these resources is the emissions they create in terms of pollution levels and green house gases. The choice of efficient technology or alternate fuel and technologies/products has a direct bearing on this c..

). The black residue left in the 1 s t tube is called coke. Coke is a fuel in its own right which can be used in homes and factories. But it is largely used as a reducing agent in the extraction of metals from their ores. It is also used in making fuel gases like water gas which is a mixture of car..
