Abstract |
The report gives results of the operation of a 13.8 kW Limestone Injection Multistage Burner (LIMB) furnace. Furnace characterization, general sorbent survey, and calcium silicate test results are also given. Several candidate sorbent materials for the full scale LIMB demonstration at Edgewater Station (Ohio) were evaluated. SO2 capture was measured while firing Pittsburgh No. 8 coal (2.6% sulfur) and natural gas spiked with SO2. Sorbent was injected at 1210 C. With a furnace quench rate of 260 C/s, the average residence time at reaction temperatures was 1.3 s. At Ca/S molar ratios of 2, Vicron 45-3 limestone reduced SO2 emissions 38% from baseline levels. Increased SO2 capture rates of 60-69% were measured for various calcitic atmospheric hydrates. Dolomitic sorbents were able to achieve captures of 73-75% and showed no significant difference between atmospheric and pressure hydrates. With the addition of sodium bicarbonate at molar Ca/Na = 15, captures of 83 and 88% were possible for the calcitic and dolomitic hydrates, respectively. Sodium bicarbonate was evaluated as a fuel additive as well as a sorbent additive. |
