A high sulphur bituminous coal, Devco Prince, containing up to 6% sulphur from Eastern Canada has been successfully burnt in 28 tests in a pilot-scale atmospheric fluidized bed combustor. Three different size consists of high calcium limestone, also from Eastern Canada, were employed to study the effect of limestone size on sulphur capture. The tests were conducted at three fluidizing velocities 1.2, 2.1 and 3 m/s, a bed temperature of 850/sup 0/C and 20% excess air. Combustion efficiency based on carbon consumption of up to 98% without recycle and up to 99.7% with recycle were obtained. The SO/sub 2/ emission guideline of 705 ng/J can be achieved with Ca/S ratio of about 2.1 with 6.3 mm x 0 and 0.84 x 6.3 mm size limestone and Ca/S ratio of about 3.3 with 0.84 x 2.38 mm size limestone with recycle. Two tests were carried out for 24 h to study the effect of longer operation on bed inventory, fluidization, sulphur capture and combustion performance.
