What is the difference between raw coal and standard coal?Data to see the "two energy production capacity of 23 million 450 thousand tons of standard coal", why do you say so? Standard coal does not belong to the two energy! Is not converted into standard coal?
Formula for:The average calorific value (kcal / kg) = [sigma (a low heat energy measured the amount of energy / energy) * Total (ton)
1 tons of crude oil = 1.43 tons of standard coal1000 cubic meters of natural gas = 1.33 tons of standard coal1 tons of raw coal = 0.714 tons of standard coal3 of the energy converted to standard coal coefficient = some actual calorific value energy (kcal / kg) /7000 (kcal / kg) before the various energy conversion standard of coal, the actual average calorific value of the first direct estimates of various energy sources, and then converted to standard coal. The average calorific value, also known as the average calorific value, refers to the weighted average value of the measured calorific value of the energy of different species or varieties.
The difference between raw coal and standard coal:1 raw coal (raw coal)The raw coal is the coal which is extracted from the ground or underground, and the coal is removed by screening and processing. Coal mine produced without washing, unprocessed raw coal is also called coal. Including natural coke and inferior coal, not including low calorific value coal. According to the degree of carbonization can be divided into peat, lignite, bituminous coal, anthracite. Coal is mainly used for power, but also a part of industrial raw materials and raw materials. Unit of measure.
2 standard coal (Standard coal):Energy containing various fuels is different, such as 1 tons of coal of about 7560 kwh, 1 tons of coal is about 2200 kwh, 1 tons of coke for 7790 kilowatt hours, 1 cubic meters of gas for 4.7 kilowatt hours. In order to use convenient, uniform standards, the comparison between the quantity and quality of energy, coal, oil and natural gas are according to a certain proportion of unified converted into standard coal to represent (calorific value of 1 kilograms of standard coal is 29 trillion and 270 billion joules, namely per ton of standard coal is 29270 MJ). The conversion method is:
