Abstract
In accordance with one embodiment of the present invention, a first vessel for holding a mixture of steam and water is disclosed. At least one first manifold is in fluid communication with the first vessel, the at least one first manifold is for receiving water from the first vessel. At least one second manifold is in fluid communication with the first vessel and in parallel spaced relation to the first manifold, the at least one second manifold is for returning a mixture of steam and water to the first vessel. At least one tube is in fluid communication with the at least one first manifold and the at least one second manifold, and a plurality of fins extends radially outward from an outer surface of the at least one tube.
Claims47
A heat recovery steam generator comprising:
- a first vessel for holding a mixture of steam and water;
- at least one first manifold in fluid communication with the first vessel, the at least one first manifold for receiving water recirculated through the first vessel;
- at least one horizontal inlet port in the side of said first vessel;
- at least one second manifold in fluid communication with the first vessel and in parallel spaced relation to the first manifold, one end of said at least one second manifold directly connected to said at least one horizontal inlet port and extending horizontally outwardly from said at least one horizontal inlet port, the at least one second manifold for returning recirculated water received by said at least one first manifold from said first vessel as a mixture of steam and water via the said at least one horizontal inlet port to the first vessel for separation into steam and recirculated water;
- at least one first tube in fluid communication with the at least one first manifold and the at least one second manifold;
