Lignite combustion test project interim report: Tests L101-L114
Fluidized bed combustion research on North Dakota lignite is being performed by Combustion Power Company, Inc. under contract to Grand Forks Energy Technology Center in a 7 sq ft Atmospheric Fluid Bed Combustor. A series of 14 parameteric tests have been completed in which various combinations of bed temperature, superficial velocity, excess air, and limestone Ca/S ratios made up the test matrix. Twelve of the 14 tests used ash recycle. The test results extend the lignite combustion characteristics determined from GFETC tests on smaller reactors with respect to: (1) sulfur retention on lignite ash and supplemental sorbents; (2) ash and bed agglomeration problems; (3) effect of operational conditions and bed characteristics on heat transfer coeffficient; (4) ash reinjection; and (5) flue gas pollutants. This interim report summarizes the test setup, test procedures and test results, describes operational problems, and provides observations noted during the tests and on post-test inspections.
