DETERMINATION OF SEGMENTED ANGULAR SHAPES FOR CIRCULAR AREAS OF THERMAL EQUIPMENT

Abstract

Most thermal equipment like industrial boilers, ceramic kilns, incinerators, thermal plants for electricity generation, have specially designed circular areas through which heat passes or generates. Since these areas are circular in design, fabrication and lining with refractory materials present technical problems that must be understood. Moreover, angular shapes that are required to construct circular areas are not readily available for procurement. These segmented angular shapes are not standardized, so depending on the make of the thermal equipment, suitable segments must be fabricated to fit. Moulds have to be fabricated and shapes cast out, using high temperature castables. These intricate procedures for the design and construction of circular segmented angular shapes have been, exhaustively, treated in this paper.
