The standard Meizhi is what mean?
Standard coal, also known as coal equivalent, has a uniform calorific value. China's per kilogram of standard coal calorific value of 7 million cards. The different varieties and different contents of energy are converted into standard coal with a calorific value of 7 million calories per kilogram according to their different heat values.Energy standard coal coefficient = the actual calorific value of some energy (kcal / kg) /7000 (kcal / kg)
There are many kinds of energy, the heat is also different, in order to facilitate mutual comparison and in the total amount of research, China's 7000 kg per kilogram of hot water (29 million 306 thousand coke) as standard coal, also known as standard coal. In addition, China has often energy converted into standard coal tonnage to 1 tons of straw, such as the energy equivalent to 0.5 tons of standard coal, 1 cubic meters of methane energy equivalent to 0.7 kilograms of standard coal.
The standard Meizhi is calorific value per kilogram of 29 million 300 thousand coke coal
