Abstract
A heat recovery steam generator (HRSG) includes a base and a top platform assembly disposed on the base. The top platform assembly includes a first top platform auxiliary module having a first rectangular frame in which a steam manifold is disposed, a second top platform auxiliary module having a second rectangular frame in which a high pressure (HP) drum is disposed, and a third top platform auxiliary module having a third rectangular frame in which a low pressure (LP) drum and an intermediate pressure (IP) drum are disposed. Each top platform auxiliary module may be pre-assembled on the ground prior to be raised to elevation for installed on the base.

A heat recovery steam generator (HRSG), comprising:
- a top platform auxiliary module having:
- a frame;
- a steam manifold, a high pressure (HP) drum, an intermediate pressure (IP) drum, or a low pressure (LP) drum disposed in the frame;
- a terminal fluid connection corresponding to the steam manifold, the HP drum, the IP drum, or the LP drum;
- and
- a mount spaced from the terminal fluid connection a predetermined distance;
- and
- a base having:
- a ridge configured to support the top platform auxiliary module by engaging the mount;
- and
- a base fluid connection spaced from the ridge a distance corresponding to the predetermined distance such that the terminal fluid connection is configured to align with the base fluid connection when the ridge engages the mount.
A method of constructing a heat recovery steam generator (HRSG), comprising:
- forming a top platform auxiliary module such that the top platform auxiliary module includes:
- a frame;
- a steam manifold, a high pressure (HP) drum, an intermediate pressure (IP) drum, or a low pressure (LP) drum disposed in the frame;
- a terminal fluid connection corresponding to the steam manifold, the HP drum, the IP drum, or the LP drum;
- and
- a mount spaced from the terminal fluid connection a predetermined distance;
- forming a base such that the base includes:
- a ridge configured to support the top platform auxiliary module by engaging the mount;
- and
- a base fluid connection spaced from the ridge a distance corresponding to the predetermined distance such that the terminal fluid connection is configured to align with the base fluid connection when the ridge engages the mount;
- lifting the top platform auxiliary module to elevation;
- and
- disposing the top platform auxiliary module on the base such that the mount engages the ridge and the base fluid connection is aligned with the terminal fluid connection.
