## Abstract

An integrated steam cycle power module (100) comprising a steam turbine (102) arranged to have steam supplied thereto; a steam manifold (104) arranged to have exhaust steam from the steam turbine supplied thereto; at least one heat exchanger (108) arranged to have exhaust steam supplied thereto from the manifold via risers which connect the manifold to headers (117) associated with the heat exchangers; and having the steam turbine situated below the steam manifold and arranged, in use, to vent exhaust steam to the manifold, which exhaust steam is passed to the heat exchanger in order to have heat extracted therefrom. Substantially all of the equipment required can be integrated into a compact module reducing plot space, overall costs and assembly time on site or allowing the module to be fabricated off site. The heat exchanger may be arranged to form substantially planar, substantially vertical walls along the side regions of the module.

## Claims

### Claim 1

An integrated steam cycle power module comprising:
a steam turbine arranged to have high pressure high temperature steam supplied thereto;
a steam manifold arranged to have exhaust steam from the steam turbine supplied thereto;
at least one heat exchanger panel arranged to have exhaust steam supplied thereto from the manifold via risers which connect the manifold to headers associated with the heat exchangers; and
wherein the steam turbine is situated below the steam manifold and is arranged, in use, to exhaust exhaust steam to the manifold, which exhaust steam is passed to the heat exchanger panel in order to have heat extracted therefrom; and wherein the or each heat exchanger panel is substantially vertical and arranged to form a substantially planar, substantially vertical, wall along side regions of the module.

### Claim 2 (depends on 1)

A module according to claim 1 wherein a steam inlet pipe is provided to carry the exhaust steam from the steam turbine to the manifold, which steam inlet pipe connects to the manifold at substantially a central region of the manifold.

### Claim 3 (depends on 2)

A module according to claim 2 wherein the steam inlet pipe is arranged to be substantially vertical.

### Claim 4 (depends on 2)

A module according to claim 2 wherein the manifold is arranged, in use, to allow steam to move in at least two directions along the module.

### Claim 5 (depends on 1)

A module according to claim 1 where the risers are provided in pairs.

### Claim 6 (depends on 4)

A module according to claim 4 wherein the risers are arranged in pairs with a first riser of the pair conveying steam to a first side of the module and a second riser of the pair conveying steam to a second, different, side of the module.

### Claim 7 (depends on 1)

A module according to claim 1 in which the heat exchanger panels comprise header pipes.

### Claim 8 (depends on 7)

A module according to claim 7 in which the risers connect to the header pipes.

### Claim 9 (depends on 1)

A module according to claim 1 wherein the module is connectable to additional heat exchanger panels.

### Claim 10 (depends on 1)

A module according to claim 1 wherein each heat exchanger panel is arranged to form a substantially planar, substantially vertical, wall along side regions of the module.

### Claim 11 (depends on 8)

A module according to claim 8 wherein the manifold is arranged, in use, to allow steam to move in at least two directions along the module.

### Claim 12 (depends on 11)

A module according to claim 11 wherein the module is connectable to additional heat exchanger panels.

### Claim 13

An integrated steam cycle, power module comprising:
a steam turbine arranged to have steam supplied thereto;
a steam manifold arranged to have exhaust steam from the steam turbine supplied thereto;
at least one heat exchanger panel arranged to have exhaust steam supplied thereto from the manifold via risers which connect the manifold to headers associated with the heat exchangers; and
a steam inlet pipe connected to the manifold at a central region of the manifold to carry the exhaust steam from the steam turbine to the manifold;
wherein the steam turbine is situated below the steam manifold and is arranged, in use, to exhaust exhaust steam to the manifold, which exhaust steam is passed to the heat exchanger panel in order to have heat extracted therefrom;
wherein each heat exchanger panel is arranged to form a planar, substantially vertical, wall along side regions of the module;
wherein the steam inlet pipe is arranged to be vertical;
wherein the manifold is arranged, in use, to allow steam to move in at least two directions along the module;
wherein the risers are arranged in pairs with a first riser of the pair conveying steam to a first side of the module and a second riser of the pair conveying steam to a second, different, side of the module;
wherein the module heat exchanger panels comprise header pipes;
wherein the module risers connect to the header pipes;
wherein the module is connectable to additional heat exchanger panels; and
wherein the manifold is arranged, in use, to allow steam to move in at least two directions along the module.
