Light hydrocarbons are treated as a by-product of the petrochemical industry. They are clean and inexpensive fuels that not only protect the environment but also save valuable energy. At present, people through the analysis of light hydrocarbon fuel development status, obtained the current light hydrocarbon fuel is mainly the use of gasification combustion, this way for light hydrocarbon quality and safety testing requirements are very strict. The feasibility of using light hydrocarbon gas as a technology to replace diesel fuel in oil boilers has been proposed for the current industrial boilers in China, and the sources of light hydrocarbon fuels and the safety of such alternative technologies have been specifically described and economic development prospects, which can eff actively reduce the sustained and stable development of the industrial economy for the international oil market dependence.
