Title: AFBC - operation of small scale demonstration for greenhouse heating

Conference ·
OSTI ID:560510

A 2.2 million Btu/hr unit prototype AFBC system was installed in 1995 at Cedar Lane Farms, a commercial nursery in Ohio. The AFBC is in operation and is heating hot water for greenhouse temperature control. A team consisting of the Energy and Environmental Research Corporation, the Ohio Agricultural Research and Development Center of Ohio State University and the Will-Burt Company developed this technology with funding support from the Ohio Coal Development Office and the U.S. Department of Energy. The system is fully automated with little operator attention being required. Operating experience at Cedar Lane Farms has shown that only 2 hours per day of operator attention is required for the system. The system includes flyash/sorbent reinjection and underbed coal/limestone feed. These features provide for good limestone utilization; a Ca/S (in coal) ratio of 2.5 will maintain an SO{sub 2} emissions level of 1.2 lb/10{sup 6} Btu when burning high sulfur (3.2 %) Ohio coal. A baghouse is used to control particulate emissions. Based on the success of the prototype unit, a design has been recently completed for a commercial size 10 x 10{sup 6} Btu/hr unit. This environmentally acceptable and cost effective coal-fired AFBC system is targeted for industrial-commercial-institutional space and process heat applications in the 5 x 10{sup 6} to 10 X 10{sup 6} Btu/hr capacity range. Multiple AFBC units can be used to provide larger beat outputs. Potential coal-fired AFBC users include institutions (schools, hospitals, prisons, government), light industry (agriculture, food processing), commercial users (shopping centers), and large residential users (apartment complexes).
