Inorganics in Fuel: a Century of Scientific and Engineeringprogress
نویسنده
چکیده
Combustion of fossil fuels has been the backbone of the power generation, manufacturing and transportation industries in the twentieth century. Although the mix of fuels has changed, at the close of the century we find that combustion systems have not changed overmuch. Operational caused by inorganic elements in fossil fuels (corrosion, slagging, and fouling) continue to present problems in combustion systems, although substantial progress has been made in understanding and addressing such problems. In the latter half of tpe century, the impact of inorganic elements in fossil fuels on the environment was recognized as a potential problem. Considerable effort has therefore been directed at understanding the behavior of certain trace metals such as mercury. arsenic, nickel, chromium, and selenium during the combustion process. This paper briefly reviews the behavior of inorganic elements in practical combustion systems as well as the progress made in applying this knowledge to improvements in operational and environmental performance.

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...
