Available in PDF, EPUB and Kindle. Book excerpt: A conceptual design for a 10-MWe Heat Pipe Central Receiver Gas-Turbine Power Plant has been developed. The heat pipe central solar receiver uses heat pipes to transform the concentrated high solar heat flux at the receiver into a lower heat flux compatible with gas heat-transfer systems. Several Brayton cycles were studied to determine which cycles and operating conditions are technically and economically most viable for a central receiver power plant. A regenerative open-gas cycle with an inlet turbine temperature of 816/sup 0/C (1500/sup 0/F) was selected. The turbine-generator and receiver are located at the top of a steel tower, with a north field of 2-axis tracking heliostats. The system can be adapted for operation as a hybrid plant, providing a higher level of availability and a dependable generating capacity - important considerations from the utility point of view. The predicted cycle efficiency is 33 to 38%, and the overall solar-to-electric efficiency is 19.1 to 22.3%. Capital cost of the plant is estimated to be in the $1,947 to $2,002/kW range, depending on the assumed cost for the collector system. Compared with a water/steam solar system, estimated costs in mid-1978 dollars are lower and plant efficiency is superior.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was the conceptual design of a Central Solar Receiver Gas Turbine Plant which utilizes a high temperature heat pipe receiver. Technical and economic feasibility of such a plant was to be determined and preliminary overall cost estimates obtained. The second objective was the development of the necessary heat pipe technology to meet the requirements of this receiver. A heat pipe receiver is ideally suited for heating gases to high temperatures. The heat pipes are essentially loss free thermal diffusers which accept a high solar flux and transform it to a lower flux which is compatible with heat transferred to gases. The high flux capability reduces receiver heating surface, thereby reducing receiver heat losses. An open recuperative air cycle with a turbine inlet temperature of 816/sup 0/C (1500/sup 0/F) was chosen as the baseline design. This results in peak metal temperatures of about 870/sup 0/C (1600/sup 0/F). The receiver consists of nine modular panels which form the semicircular backwall of a cavity. Gas enters the panels at the bottom and exits from the top. Each panel carries 637 liquid metal heat pipes which are mounted at right angle to the gas flow. The evaporators of the heat pipes protrude from the flux absorbing front surface of the panels, and the finned condensors traverse the gas stream. Capital cost estimates were made for a 10 MW(e) pilot plant. The total projected costs, in mid-1978 dollars, range from $1,947 to $2,002 per electrical kilowatt. On the same basis, the cost of a water/steam solar plant is approximately 50% higher.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program is the development of a solar-to-gas heat exchanger for a Central Receiver Power Plant. The concept is based on the use of heat pipes to transfer the concentrated solar flux to the gaseous working medium of a Brayton cycle conversion system. An open air cycle with recuperator and a turbine inlet temperature of 800/sup 0/C (approximately 1500/sup 0/F) was selected as the optimum choice. It yields a conversion efficiency of approximately 32 percent and an overall solar-to-electric efficiency of 20 percent. The light weight of gas turbine equipment opens the possibility of tower mounting the entire system. Three potential receiver configurations have been identified, two of them being of the cavity type and one being an external receiver. The required thermal diffuser heat pipes use liquid metal as the working fluid. The optimum size is approximately 5 cm in diameter and 2 to 3 m in length. The design axial heat flux is 10 MW/m/sup 2/ which corresponds to a heat transfer rate of 20 kW per heat pipe. The theoretical foundations of these heat pipes have been developed and subscale prototypes have been tested successfully. The radial and axial heat fluxes of the prototypes met and exceeded the requirements for the full-scale heat pipes.
