Abstract
The Fluidized-Bed Waste-Heat Recovery
(FBWHR) System is a combustion air preheater
designed for existing unrecuperated industrial
furnaces, where dirty and corrosive flue gases
cause severe fouling and materials problems. The
FBWHR system solves these problems by using a
durable, direct contact heat exchanger, eliminating
conventional gas-to-air heat exchanger surfaces.
In the FBWHR system, a recirculating particulate
medium is heated as it falls through upwardflowing
flue gases in a raining-bed heat exchanger.
This heated medium is passed across a fluidized-bed
heat exchanger, preheating the combustion
air. Cooled medium is returned to the raining bed
for reheating.
This paper discusses FBWHR system pilot
plant testing that surpassed program goals. A
description of the initial steps of a full-scale
FBWHR system demonstration is also included.
