  • What is the difference between cogeneration and

    Gas turbines and boiler power plants are the two most common methods. In a gas turbine, gas is ignited under pressure and combustible high-pressure, high-temperature gases are produced. In a boiler power plant, electricity is generated by heating water to produce steam which, via a turbine, powers a generator.

  • Boiler | Engaged in Thermodynamics

    In the combined power cycle, hot exhaust gas from a gas turbine is fed into a HRSG to generate steam which in turn drives a steam turbine. There are four main components in an HRSG: the evaporator, superheater, economizer, and water pre-heater. Within the HRSG are many layers of long tube bundles filled with high-purity water.
