【 摘 要 】

Combustion testing of sunflower-coal blends on Boilers No. 3 and 5 at the University of North Dakota (UND) Steam Plant facility was completed. A total of four combustion tests were performed. In each boiler, a baseline combustion test was performed on subbituminous coal and a combustion test was performed on a sunflower-coal blend of approximately 25 wt% sunflower hulls. A cold-flow test was also performed on the boiler feed system. A summary review of the test results is included in this report, along with pictures. Additional analysis is currently being performed on the combustion test data. We have completed Task 2, Fuel-Handling Issues, and are currently working on completing Tasks 3 and 5. Accomplishments for this quarter: (1) Successfully mixed sunflower-coal blend in the UND Steam Plant facility's current feed system. (2) Successfully combusted a 25% sunflower-75% coal (approximately) blend in Boilers No. 3 and 5. (3) Identified potential dust problems with the feed system. (4) Identified potential feed problems at the stokers and in the fireboxes. (5) Obtained test data on the combustion tests.
