Problems solved by technology

When there is no means of burning part of the spent fuel, the heat content of these components is wasted, thus reducing the thermodynamic efficiency of the plant
In addition, unburned hydrocarbons may also be undesirably emitted into the atmosphere when the fuel used in the fuel cell is not fully converted

Abstract

A hybrid power plant (10) includes a turbine (14), a compressor (12) driven by the turbine and a recuperator (20) in flow communication with the compressor. The recuperator is configured to transfer heat from turbine exhaust (52) to compressed air, and at least one fuel cell (34) is in flow communication with said recuperator to provide fresh air for said fuel cell.

Description

technical field [0001] The present invention relates generally to power plants and, more particularly, to hybrid power plants including integrated fuel cells. Background technique [0002] In some hybrid power generation systems, fuel cells are combined with conventional gas turbines to increase the amount of power generated (efficiency) in the power plant. Known fuel cells, such as solid oxide fuel cells, include multiple solid fuel cells that react a gaseous fuel, such as reformed natural gas, with air to produce electricity and high temperature gas. The gas turbine compressor supplies air to the fuel cell, which operates at high pressure, and the fuel cell produces high temperature gas for expansion within the turbine. The fuel cell stack exhaust gas is combined with the fuel cell stack exhaust fuel and the resulting thermal emissions are converted successfully in the turbine section of the plant. Therefore, electricity is generated by a solid oxide fuel cell generator ...
