Supercritical heat recovery steam generator reheater and supercritical evaporator arrangement

摘要

A supercritical heat recovery steam generator includes a duct defining an interior area and having a gas inlet and a gas outlet. The duct is configured to convey gas from the gas inlet to the gas outlet. A portion of the duct between the gas inlet and the gas outlet defines an exhaust gas flow segment of the interior area. A supercritical evaporator is disposed in the interior area and a reheater is disposed in the interior area. The reheater and the supercritical evaporator are disposed in the exhaust gas flow segment, adjacent to each other with respect to the flow of the exhaust gas.
