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.

公开了在稳态条件下降低排放水平的方法,用于干式洗涤器脱硫系统。 将干燥的氢氧化钙粉末注入气体流动路径并浇注在喷雾干燥器吸收器中。 然后将所得浆液沉积在袋式除尘器中的过滤袋上。 这可以在比喷雾干燥器吸收器更低的温度下进行,否则可以操作,使得能够在燃烧过程中更早地发生脱硫,特别是在环境温度下的冷却锅炉启动期间。 锅炉的操作也可以根据各种操作情况进行备份,组成,修整或增加。
