Abstract

A solar receiver, designed to use a heat transfer medium, includes a plurality of panels. Each panel is arranged and configured to enable the heat transfer medium to flow in at least one flow direction, one flow direction defining a pass, to obtain unique mass flux in each pass to optimize the heat flux capability of the pass while minimizing pressure drop across the selected passes of the heat transfer surface. A method thereof is also provided.

First claim

What is claimed is:

1. A solar receiver, having a heat transfer medium, for a solar power system, the solar receiver comprising:
a plurality of panels defining a heat transfer surface, each panel arranged and configured to enable the heat transfer medium to flow in at least one flow direction, the at least one flow direction defining a pass to obtain various mass fluxes in various passes to optimize heat flux capability of the pass based on the location of the pass in the heat transfer surface in order to minimize a Lost Heat Flux Design Space (LHFDS) of the heat transfer surface, thereby improving the efficiency of the solar receiver,
wherein each panel is comprised of a plurality of tubes, the plurality of tubes in a first panel comprising a different material, tube thickness, or number of tubes than the plurality of tubes in a second panel to give the first panel a different mass flux than the second panel.

2. The solar receiver as claimed in claim 1 , wherein the LHFDS is an unutilized design space of the heat transfer surface and is a difference between a Maximum Allowable Heat Flux (MAHF) and an Actual Heat Flux (AHF) of the heat transfer surface.

3. The solar receiver as claimed in claim 1 , wherein the heat transfer surface is configured based on parametric consideration of a solar field capability of the system, pressure drop of the system and thermal losses from the heat transfer surface.

4. The solar receiver as claimed in claim 1 , wherein the plurality of tubes in the first panel comprises a different material than the plurality of tubes in the second panel.

5. The solar receiver as claimed in claim 1 , wherein the plurality of tubes in the first panel comprises a different tube diameter than the plurality of tubes in the second panel.

6. A solar receiver, having a heat transfer medium, for a solar power system, the solar receiver comprising:
a plurality of panels defining a heat transfer surface, each panel having a plurality of tubes arranged and configured to enable the heat transfer medium to flow in at least one flow direction, the at least one flow direction defining a pass to optimize heat flux capability of the various passes based on the location of the pass in the heat transfer surface in order to minimize a Lost Heat Flux Design Space (LHFDS) of the heat transfer surface,
wherein the plurality of tubes in a first panel comprises a different material, tube thickness, and number of tubes than the plurality of tubes in a second panel to give the first panel a different mass flux than the second panel.
