HIGH TEMPERATURE SENSIBLE HEAT STORAGE OPTIONS.

Abstract

Alkali-metal carbonate salts meet the requirements for high temperature solar central receiver systems, but due to their corrosiveness, special problems arise in the design of storage tanks. In particular, to reduce corrosion and temperature sufficiently to retain strength in the containing wall, internal thermal insulation is required. This paper presents design options and operation criteria for sensible heat molten salt storage with internal insulation.
