Gas-Turbine Fuel

Gas-Turbine Fuel 

hydrocarbon gases or liquid petroleum fuel used in gas turbines.

Gaseous fuels such as natural gases are mainly used in gas turbines that power pumping stations along main gas pipelines. Liquid fuels are used in gas-turbine-powered transport vehicles (motor vehicles, locomotives, and ships) and in large stationary gas turbines. Distillates produced by petroleum distillation and by the processing of products of cracking, as well as from slow carbonization of mazut and other petroleum by-products, are among the liquid fuels used in gas turbines. The main requirements of a gas-turbine fuel are low vanadium content [(2-6) × 10^-4 percent] and low ash content. An additive is placed in gas-turbine fuel to reduce corrosion of the blades and to prevent the deposit of carbon and ash. Soviet industry produces two types of gas-turbine fuel, which congeal at -5° C (for gas-turbine engines in locomotives) and -12° C (for other mobile and stationary gas turbines).
