What do you mean by fossil fuel, liquefied gas and gas?

Fossil fuel, also known as fossil fuel, is a hydrocarbon or its derivative. The natural resources contained in fossil fuels are coal, oil and natural gas. The use of fossil fuels can make the industry develop on a large scale, instead of waterwheels, wood or peat can be burned and heated.

liquid gas

Liquefied petroleum gas (LPG) is short for liquefied petroleum gas, and its main components are propane and a small amount of butane. Liquefied petroleum gas (LPG) is stored in liquid state in storage tanks under appropriate pressure. In order to prevent air leakage, ethanethiol additive is used to deodorize liquefied gas.

Liquefied petroleum gas contains almost no combustible components, with high calorific value, full combustion and no dust and ash. Therefore, liquefied petroleum gas is a kind of clean energy, and its use can reduce air pollution and protect the environment. The heat released by the combustion of liquefied gas is the highest among ordinary gas, and its calorific value is11000-12000 kcal/kg, which is six times that of ordinary gas and higher than that of natural gas. Therefore, liquefied gas is often used as cooking fuel and vehicle fuel, and is also widely used for heating in enterprise production and processing.

coal gas

coal gas

A gas containing combustible components made from coal. According to the processing mode, gas properties and uses, it can be divided into: water gas, semi-water gas and air gas (or producer gas) obtained by coal gasification, which are collectively called low calorific value gas because of their low calorific value; The gas obtained by coal carbonization coking is called coke oven gas, which belongs to medium calorific value gas and can be used as urban civil fuel. Carbon monoxide and hydrogen in coal gas are important chemical raw materials, which can be used for synthetic ammonia and methanol. Therefore, the gas used as chemical raw material is called synthetic gas, and it can also be made of natural gas, light oil and heavy oil.
