Fluidized-bed combustion: industrial application demonstration projects. Quarterly technical progress report, July 1--September 30, 1977

A subscale experimental unit is being designed and constructed and will be used to develop design information for a 25,000 lb/hr demonstration industrial steam generator using an advanced fluidized-bed combustion process. Nominal design for the subscale unit is a firing rate of 400 lb coal per hour and a bed cross section of approximately 2 square feet. Construction work in the Subscale Experimental Unit System was completed on August 10, 1977. Five shakedown runs, including a 48-hour uninterrupted run, were made and needed equipment and operation procedure changes identified and accomplished. The equipment is ready for experimental operation.
