| Abstract |
The report gives results of pilot-scale studies of sulfur capture in the EPA's Limestone Injection Multistage Burner (LIMB) process and the effect of LIMB on particulate properties and electrostatic precipitator (ESP) performance. The sulfur capture studies showed that hydrated lime was generally superior to limestone as a sorbent for in-furnace sulfur removal. For both sorbents, downstream injection was found to be preferable over near-flame injection. With hydrated lime, the optimum injection temperature was found to be about 1200 C, where utilizations as high as 30% were achieved. The injection of either sorbent resulted in a large increase in the electrical resistivity of the ash, which could severely impact ESP performance. Laboratory and pilot-scale studies showed that the resistivity increase could be offset by flue gas conditioning using sulfur trioxide (SO3) or water vapor. With limestone injection, acceptable resistivity levels were restored by the injection of 30 ppm of SO3. |
