Performance Evaluation of Scheffler Concentrator
Abstract
Scheffler concentrator, used widely for cooking purpose, is simple in design and efficient, hence performance analysis of the reflector is essential. In this regard, an experiment is conducted to evaluate its performance. A lateral section of paraboloid having fixed focus at a distance is taken as a reflector to minimize the effect of the shadow of the receiver. The water contained in a dome shaped receiver located at fixed focus, gets converted into steam and collected in the steam header until ample pressure is reached and further, it can be utilized for cooking purpose.
