Gaseous Fuel

Natural and artificial gas is used as energy fuel. Natural gas is divided into to groups: pure gas – field and oil gas (side gas). The composition of the different fields of natural gas is not the same, but in all cases it contains very much propane (75…98 percent). Natural gas contains a small amount of higher hydrogens – ethane, propane, butane and their total quantity is not more than 10 percent. Internal ballast forms a little part in the natural gas: carbon oxide – 0,1…1,0 percent, nitrogene 1…14 percent. Combustion heat of natural gas is very large (about 35000 kJ/m3).

Artificial gas (gas of generators, blast – furnace, coking etc.) contains much internal ballast, combustion heat is smaller (4000…16000 kJ/m3), so it is used as local fuel. Gaseous fuel in comparison with solid and liquid fuel has many advantages: transportation to the consumers is convenient, easy mixing with air in the furnaces, service and control of burning process. Natural gas is the cheapest fuel, its price is less than that of coal and oil. Liquified gas consisting of low pressure propane and butane is used to satisfy everyday needs.
