Title:
REVERSIBLE RECUPERATOR
Document Type and Number:
WIPO Patent Application WO2001063175
Kind Code:
A3
Abstract:
The recuperator (22) includes a heat exchanger core (50) having a standard construction. Air and gas side passages (52, 54) are formed within the heat exchanger core. Compressed air is supplied to an air inlet manifold (56), which distributes the compressed air to the air side passages in the heat exchanger core. Air leaving the air side passages is collected by an air outlet manifold (58). The turbine exhaust gas stream enters a first face (60) of the heat exchanger core, flows through the gas passages in the core, and exits from a second face (62) of the heat exchanger core. As the turbine exhaust gas is passing through the gas side passages, combustion products in the turbine exhaust gas can condense and build up on cooler sections of the gas side passages. The heat exchanger core can be rotated by 180 degrees about a pivot point A, whereby the positions of the inlet and outlet manifolds are reversed.
