相关概念：标准煤(标煤)标准煤(Standard coal)各种燃料的含能量是不同的。如1吨煤约7560千瓦/小时,1吨泥煤约为2200千瓦/小时,1吨焦炭为7790千瓦/小时,1立方米煤气为4．7千瓦/小时等。为了使用的方便,统一标准,在进行能源数量、质量的比较时,将煤炭、石油、天然气等都按一定的比例统一换算成标准煤来表示(1公斤标准煤的热值为29．27兆焦耳,即每吨标准煤为29270兆焦耳)。其换算方法为：
Related concepts: Standard coal (Standard coal) The energy content of various fuels is different. Such as 1 ton of coal about 7560 kilowatts / hour, 1 ton of peat is about 2200 kilowatts / hour, 1 ton of coke is 7790 kilowatts / hour, 1 cubic meter of gas is 4.7 kilowatts / hour and so on. In order to facilitate the use of a unified standard, in the comparison of the quantity and quality of energy, coal, oil, natural gas and so on are all converted into standard coal according to a certain proportion. (The calorific value of 1 kilogram of standard coal is 29.27 trillion Joule, or 29,270 Megajoules per tonne of standard coal). The conversion method is:
