GAS TURBINES AND JET ENGINES 5.1 Introduction
personal.utulsa.edugas turbine is an example, like the steam power plant, of an external combustion engine. This is in contrast to internal combustion engines, such as automotive engines, in which combustion takes place in the working fluid confined between a cylinder and a piston, and in open-cycle gas turbines. 5.3 Analysis of the Ideal Cycle

www.nrel.govsteam or hot water is piped up from the well to drive a conventional steam turbine, which powers an electric generator. Typi-cally, the water is then returned to the ground to recharge the reservoir and com-plete the renewable energy cycle. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle.
Fossil Energy Study Guide: 300 million years ago
www.energy.govTh e burning coal heats water in a boiler, creating steam. 4. Steam from the boiler spins the blades of an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine. 5. Th e spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy.
