Investigation of bed ash agglomeration during the screening tests. [Including adsorbent]

Technical Report ·
OSTI ID:6281294
After extensive testing of the UK coal/sorbent mixture in the Experimental Pressurized Fluidized Bed Combustion Facility at Grimethorpe, South Yorkshire, UK, a series of 100-hour tests was carried out to characterize one USA and two FRG fuel blends. During these tests, bed ash agglomeration occurred within the in-bed tube bank and in the space between the tube bank and the distributor plate. As this phenomenon had not occurred during testing with the UK fuel blend, an investigation was initiated. The fuel blend properties and the design and operation of the combustor were reviewed. The investigation revealed that the agglomeration was most likely the result of poor mixing in the bed caused by local regions of less than adequate fluidization. Suspected causes of this poor fluidization immediately above the distributor plate were the absence of fluidizing nozzles in the region of th
