Dry sorbent injection during non-steady state conditions in dry scrubber |
| abstract |
Disclosed are methods of reducing emissions levels during non-steady state conditions for use with a dry scrubber desulfurization system. A dry calcium hydroxide powder is injected (794 or 796) into the gas flowpath at an injection location downstream of the combustion chamber (705) and upstream of the bag house (770) and watered (762) in the spray dryer absorber (760), wherein the resulting slurry is then deposited on the filter bags in the baghouse. The disclosed method is performed at lower temperatures than the spray dryer absorber would otherwise be operable, enabling desulfurization to occur earlier in the combustion process, particularly during startup of a cold boiler at ambient temperature. The operation of the boiler can also be backed up, made up, trimmed, or augmented depending on various operating scenarios. |
