Indirect two-stage solar concentrating cooking system

Abstract

The objective of this paper publication is a solar radiation concentrating collector with high temperature storing device for domestic and commercial use, primarily for solar cooking. This system is economical, not so difficult to use and maintain and not dangerous. The system should collect energy over 3000C for facilitating cooking, baking and frying. Individual commercial plants can be sized to produce more than 1000 people’s meals within a short time. In this technology uses sun-tracking mirrors commonly known as two-stage solar concentrating system sunlight on a receiver at the midpoint of bottom an oil circulating pipes. The massive amount of solar energy in the form of sun rays, concentrated at parallel pipe to produce temperature approximately 250°C to 300°C. The accomplished thermal energy is adapted for mineral oil, which keep back the energy for future use. High temperature water heating is converted to superheated steam, which is adapted to transfer the heat generator. In this fashion thermal energy is converted into concentrating solar cooking systems.
