The State University of New York at Cobleskill has launched an alternative energy program that will foster the utilization of agricultural and cafeteria wastes for the production electrical power through the conversion of wastes to clean fuel gas (also known as syngas). The project is being funded by the Department of Defense utilizing a patent pending rotary kiln gasifier developed by W2E USA Inc. The rotary kiln gasification system is uniquely suited for handling a variety of difficult feedstocks with sizes, shapes, moisture levels, and compositions that cannot be used in most gasifiers. The first major initiative is the installation of a 300 kW bench-scale waste to energy test facility that will provide an effective and economical means of developing gasification design data for a variety of wastes. W2E’s rotary kiln gasifier has a unique internal arrangement for introducing reactant gases at various locations within the gasification zone allowing for the adjustment of temperature and gas distribution to optimize gasification. Additionally, this permits an increase in temperature at the gasifier outlet to crack tars into smaller hydrocarbon chains to minimize tar production. This unit will be used to develop design criteria for a future 1 megawatt demonstration plant.
