Conversion method of calorific value of each energy fuel
December 22, 2018 Anonymous

Energy fuel refers to combustible substances. According to the state of the material, it can be divided into solid fuels, such as: coal, oil shale, and coke from coal processed products; liquid fuels, such as petroleum and gasoline and diesel products after processing; gas fuels, such as gas and natural gas . According to the source, it can be divided into: natural fuels, such as coal, petroleum, natural gas, oil shale, etc .; artificial fuels or synthetic fuels, such as synthetic petroleum, synthetic gasoline, etc. In addition, there are nuclear fuels that use the nuclear reaction to release huge heat. Fuel plays an important and indispensable role in industrial and agricultural production, transportation and people's lives. With the further intensification of the environmental protection situation, it is the general trend that a variety of clean fuels gradually replace the old energy fuels in the production of lime. Today we come to understand the nature of various fuel energy and its conversion and use methods.

Steam conversion

级蒸汽 = 0.131429 kg 标煤 1kg 10.0MPa class steam = 0.131429 kg standard coal
级蒸汽 = 0.125714 kg 标煤 1kg 3.5MPa steam = 0.125714 kg standard coal
级蒸汽 = 0.108571 kg 标煤 1kg 1.0MPa steam = 0.108571 kg standard coal
级蒸汽 = 0.094286 kg 标煤 1kg 0.3MPa steam = 0.094286 kg standard coal
小于 0.3MPa 级蒸汽 = 0.078571 kg 标煤 1kg less than 0.3MPa steam = 0.078571 kg standard coal  

Note: The average low calorific value in this table is expressed in kilocalories. To convert to joules, simply multiply by 4.1816.
