Alternatives to ceramic bricks and ceramic-brick systems

PDF Version Also Available for Download.

Description

Alternative materials for use as TES media in electric storage furnaces have been evaluated and selected. Selections were based on: low cost; availability; durability; and energy storage density. The materials selected were: taconite pellets; river gravel; crushed stone; and crushed (air-cooled) blast furnace slag. Essential material properties and energy storage densities were established. A conceptual design for an electric storage furnace using these low-cost materials has been developed. The performance of this conceptual furnace has been characterized by use of an analytical model. A computer code for the model has been developed. Existing performance data for present-day electric storage furnaces ... continued below

Description

Alternative materials for use as TES media in electric storage furnaces have been evaluated and selected. Selections were based on: low cost; availability; durability; and energy storage density. The materials selected were: taconite pellets; river gravel; crushed stone; and crushed (air-cooled) blast furnace slag. Essential material properties and energy storage densities were established. A conceptual design for an electric storage furnace using these low-cost materials has been developed. The performance of this conceptual furnace has been characterized by use of an analytical model. A computer code for the model has been developed. Existing performance data for present-day electric storage furnaces have been evaluated, and performance and design comparisons between present-day furnaces and the prototype furnace have been made. With the limited data at this time, a significant cost advantage for the proposed furnace, with equivalent performance, over existing electric storage furnaces cannot be established. Future work required for materials testing and component development has been identified.
