Conceptual Design of an Advanced Water/Steam Receiver for a Solar Thermal Central Power System

Abstract

This paper describes the conceptual design of an advanced water/steam receiver for a commercial-scale solar central receiver thermal power system. The objective was to develop a receiver concept featuring an optimum combination of cost, performance, and reliability. While interfaces with other major subsystems of the complete power plant were recognized, emphasis was on the design and and performance of the receiver. The baseline thermal rating of this receiver was 550 MW, and the steam outlet conditions were 12,860 kPa and 516 C. After technical and econmic evaluations, a quad-cavity, natural-circulation concept was selected as the preferred receiver design. It consists of four separate cavities in a single receiver unit, each cavity receiving concentrated solar energy from one quadrant of a surrounding heliostat field.

Thermodynamic performance evaluation of solar and other thermal power generation systems: A review

“…Zoschak et al [80] focused on the design and operating aspects of a 10-MW cavity-type, natural circulation steam generating receiver for a central-receiver thermal power plant. Wu et al [81] described the conceptual design of an advanced water/steam receiver for a commercial-scale solar central receiver thermal power system. It consists of four separate cavities in a single receiver unit, each cavity receiving concentrated solar energy from one quadrant of a surrounding heliostat field.…”
