Design and construction of a high-temperature gas receiver utilizing small particles as the heat exchanger (SPHER). Phase I report
The Small Particle Heat Exchange Receiver (SPHER) operates by injecting a very small mass of ultrafine carbon particles into a gas stream and exposing the suspension to sunlight that is focused through a window. The particles absorb the sunlight and act as very efficient heat exchangers to transfer the heat to the gas. The particles continue to heat until they react chemically or vaporize. The principles, design philosophy, and construction of a SPHER receiver are described. The system consists of two major components, the particle generator and the receiver. Analytical work is presented on optical properties and thermal properties of small particle suspensions and on particle production and oxidation. Also described is the instrumentation to monitor the operation of the particle generator and receiver. All major subsystems were built and most have undergone laboratory check out. Particle generator test results are described. Appended is a paper on the performance analysis of a SPHER. (LEW)
