摘要： Heat flow from a steam seal header could be used in a stage, such as a low pressure stage, of a steam turbine. However, the dump steam temperature from the steam seal header can be too high requiring removal of excess heat, typically through attemperation, before the dump steam is provided to the low pressure stage. Attemperation poses reliability and life issues and lowers efficiency. To address such short comings, one or more heat pumps are used to transfer heat from the dump steam to the fluid entering a boiler. This allows the dump steam temperature to be within acceptable limits, and at the same time, increase the temperature of the fluid so that the steam cycle performance is enhanced. Preferably, solid-state heat pumps are used as they are reliable, silent and can be precisely controlled.

摘要： A gas turbine includes at least one combustor and an exhaust frame; a compressor adapted to supply air to the combustor and to supply bleed air to the exhaust frame. A cooling air supply duct is arranged to supply ambient air to the exhaust frame and at least one ejector is. arranged to supply the bleed air to the cooling air supply duct upstream of the exhaust frame. A control valve is configured to control the supply of compressor bleed air to the cooling air supply duct and to the exhaust frame as a function of turbine exhaust temperature and/or turbine load conditions and cooling requirements at the various turbine load conditions.

摘要： A gas turbine inlet system includes a first passage that delivers inlet air to a compressor, a second passage that delivers fuel to a combustor, and a heat pump that transfers heat from the inlet air to the fuel by consuming electric power. The heat transfer causes the turbine inlet air temperature to drop and fuel temperature to increase with favorable effects on both turbine output and heat rate.
