Diesel Engine & Gas Turbine Power Plants topics include: Diesel engine basis, types and its applications and diesel engine analysis. Diesel power plants and gas turbine power plants are different types of power generation systems that use different fuels and technologies to produce electricity.  Here are some ways diesel and gas turbine power plants compare: Fuel: Diesel power plants use diesel fuel, a liquid hydrocarbon fuel, as their primary source of energy. Efficiency: Gas turbines are generally more efficient than reciprocating internal combustion engines (RICE) at converting fuel... Show more
