摘要
Methods of reducing emissions levels during steady-state conditions are disclosed for use with a dry scrubber desulfurization system. A dry calcium hydroxide powder is injected into the gas flowpath and watered in the spray dryer absorber. The resulting slurry is then deposited on the filter bags in the baghouse. This can be done 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.
