3Terminologies and Definitions
For the purposes of this document, the following terminologies and definitions apply.
3.1
Liquid fuel
Natural organic fuel that is in liquid form under normal temperature and the liquid fuel obtained by processing the above natural organic fuel, such as light fuel oil and heavy fuel oil.
3.2
Gaseous fuel
Natural organic fuel or artificial fuelin the solid form under normal temperature.They are divided into light gas and heavy gas according to the relative density.The gas withrelative density lower than 1.3 is classified as light gas, for example natural gas, coke oven gas and blast furnace gas; the gas withrelative density higher than 1.3 is classified as heavy gas, for example, liquefied petroleum gas.
