Abstract

A Haynes 230 micro-pin solar receiver has been designed and fabricated using a wide variety of manufacturing techniques. This receiver utilizes a modular design that allows for high temperature and pressure operation in a gas-phase CSP system. Several failure modes related to design and fabrication processes were identified in the first receiver prototypes. This paper reports the efforts to resolve the failure modes related to diffusion bonding, brazing and welding of the Haynes 230 micro-pin receiver. A systematic approach starting with separate effects and then integrated testing was used to qualify each process. At the end of this process, a 15 cm x 15 cm prototype solar receiver was fabricated and proof test to a pressure of 41.4 MPa, qualifying it for on-sun testing in future work.
