摘要

1. Compressive strength of bricks: 2. Decreases as RHA increases 3. Increases as firing temperature increases 4. Water absorption of bricks: 5. Increases as RHA increases 6. Decreases as firing temperature increases 7. Resistance to heat transfer of bricks: 7. Increases as RHA increases 8. Increases as firing temperature increases 9. Cumulative methane generation 33% higher for RHA reactor.
