Abstract
A steam generator comprising a vessel having an inlet and an outlet, and in use a primary fluid flow enters the vessel through the inlet and exits the vessel through the outlet. A plurality of modules are connected in series and at least partially housed within the vessel, and each module comprises at least one tube. The modules are arranged such that at least one tube of one module is coaxial with at least one tube of an adjacent module so as to define a conduit through which a secondary fluid can flow from one module to an adjacent module.
Claims15
A steam generator comprising:
- a vessel having an inlet and an outlet, in use, a primary fluid flow enters the vessel through the inlet and exits the vessel through the outlet;
- and
- a plurality of modules connected in series and at least partially housed within the vessel, wherein each module comprises at least one tube and the modules are arranged such that at least one tube of one module is coaxial with at least one tube of an adjacent module so as to define a conduit through which a secondary fluid can flow from one module to an adjacent module.
A steam generator comprising one or more tube bundles, the steam generator being configured to receive a secondary flow through the tube bundles and a primary flow outside the tube bundles;
- wherein each tube bundle comprises a first sub-bundle connected in series to a second sub-bundle,
- wherein each of the first and second sub-bundles comprise a plate including a plurality of holes, each hole receiving a tube of the respective first or second sub-bundle, and
- wherein the plate of the first sub-bundle connects to the plate of the second sub-bundle and the first and second sub-bundles are arranged such that the tubes of the first sub-bundle are substantially coaxial to the tubes of the second sub-bundle, such that in use, fluid flows from the first sub-bundle to the second sub-bundle.
