Air-steam gasification of dried manure-straw mixture

Authors: Sadaka, S
Description: High moisture content of dairy manure (>90%) is one of the limiting factors which diminishes its utilization in the gasification process. Adding wheat straw to manure to adjust its moisture content to about 60% then applying the biodrying technique resulted in a significant reduction of manure moisture content to about 30%. The resulted material was further air dried to about 15% and gasified in an auger gasification system. Air-steam mixture was used as the gasifying agent. The effects of steam to air ratios (0.05, 0.15 and 0.25 kg/kg) and reactor temperatures (800, 900 and 1000 oC) on the producer gas quality and quantity and char and tar production rate as well as the overall mass and energy balances were investigated. The results of this study will be presented.
