Abstract
A combined cycle power plant includes a gas turbomachine system including a compressor and a gas turbine that extracts work from gases at a first temperature. The combined cycle power plant also includes a steam turbomachine system including at least one steam turbine that extracts work from gases at a second temperature. The combined cycle power plant further includes a heat recovery steam generator having a main housing fluidly connected to the gas turbine. The heat recovery steam generator includes a plurality of heat pipes that extend within the main housing in fluid communication with the gases at the first temperature. The plurality of heat pipes are also in fluid communication with the gases at the second temperature. The plurality of heat pipes absorb heat from the gases at the first temperature and pass the heat into the gases at the second temperature to form gases at a third temperature.
