Liquefied petroleum gas, artificial gas, the calorific value of natural gas
Every kilograms of liquefied gas calorific value of 11000 kcal. Gaseous liquefied gas proportion is 2.5 kg / m3. Per cubic liquefied gas calorific value of 25200 kcal. This can be seen in a cubic liquefied gas burning natural gas calorific value is three times, but there are also reports that 7 times the calorific value of natural gas is liquefied gas.Each bottle of liquefied petroleum gas weighs 14.5 kg, a total calorific value of 159500 kcal, equivalent to the combustion heat value of 20 cubic meters of natural gas
The gas from coal or coke and other solid material, through carbonization or vaporization was prepared, its main components are carbon monoxide, methane and hydrogen. Therefore, toxic gas, air to form explosive mixtures, use should be paid attention.Natural gas general refers to buried in the earth's natural gas formation. But usually called natural gas only refers to a flammable gas rich in hydrocarbon storage in deeper strata, and natural gas and oil symbiosis is often called the oil gas. Natural gas from organic substances into the hundreds of millions of years ago. Here, the main component is methane, formed according to different geological conditions in addition, still containing different amounts of ethane, propane, butane, pentane, hexane and other low carbon alkane and carbon dioxide, nitrogen, hydrogen sulfide and other non hydrocarbons; some gas also contains helium. Natural gas is an important energy source, widely used city gas and industrial fuel; in 70s the world energy consumption, natural gas accounted for about 18% ~ 19%. of natural gas is an important chemical raw material.The calorific value of gas per cubic meter is 8000 kcal to 8500 kcal
People's lives in the combustion gas sources can be roughly divided into liquefied petroleum gas (Y), artificial gas (R), natural gas (T) three categoriesLiquefied petroleum gas (referred to as LPG) is a kind of oil gas remaining oil in refining gasoline, kerosene, diesel oil, heavy oil and other oil products in the process, through certain procedures, the oil exhaust gas recycle, take measures to make it into a pressurized, liquid, installed in the pressure vessel, the name of the resulting liquefied gas. Its main components are ethylene, ethane, propylene, propane and butane, a liquid in the cylinder, the combustible gas once the outflow will vaporize into about two hundred and fifty times than the original volume, and easy to spread, encountered the fire will burn or explode. Therefore, the use of liquefied gas also pay special attention to.
