Title: High temperature gas receiver utilizing small particles

Conference ·
OSTI ID:5567857

The purpose of the work is to develop a new type of solar thermal receiver that utilizes a dispersion of very small particles suspended in a gas to absorb the radiant energy from concentrated sunlight. The Small Particle Heat Exchange Receiver (SPHER) operates by injecting a very small mass of fine, light-absorbing particles into the gas stream. The gas-particle mixture then enters a transparent heating chamber into which the concentrated solar flux is directed. The particles absorb the radiation and because of their very large surface area, quickly transfer the heat to the surrounding gas. The gas-particle mixture continues to heat until the particles oxidize or vaporize. The gas may be heated to medium or high temperatures as suitable for a variety of industrial process heat or thermal power requirements. In particular it can be used as a high efficiency receiver to supply hot air or gas to operate a chemical or fuel production process. Research progress is summarized. (WHK)
