Preliminary design of a subscale ceramic helical-rotor expander
Abstract
A program was undertaken to develop a class of fuel-tolerant ceramic expansion engines believed to have the potential for operating reliably and efficiently on the unmodified combustion products of coal. Such engines, operating essentially uncooled at temperatures in excess of 1350/sup 0/C, appear attractive for original and retrofit applications in automotive, propulsion, industrial, and especially topping-cycle service for central power stations. The demonstration of a first small-scale (125-mm rotor diameter) ceramic helical-rotor expander has been identified as an early and feasible program goal. Design concepts and preliminary designs being considered for the prototype are described. In addition to expander design, the initial program includes consideration of the key questions of expander performance, combustion-product tolerence, materials and component evaluation and development, along with planning for development to intermediate (600-mm) and power-station-scale (1600-mm) applications. Progress in these and other programatic aspects is summarized briefly.
