Abstract: Disclosed herein is a method for reducing the amount of coarser particles from a stream of flue gas prior to treatment by a spray dryer absorption process (SDA). The method comprises the steps of directing a stream of flue gas containing entrained particles of varying sizes through a curve, thereby subjecting the particles to a centrifugal effect, collecting the particles predominately of the coarser size at a particles collecting means provided in the outer circumference of the curve, dispersing the flue gas reduced in particles of coarse particle sizes into the chamber of a spray dryer absorption apparatus, wherein the particles content of the original flue gas stream is above 20 g/Nm 3 . Also an apparatus for performing the method and a gas disperser is disclosed. The method substantially reduces the cost of the entire plant for treating flue gas having a high content of entrained coarse particles by eliminating the need for a particle pre-collector upstream the SDA.

Abstract translation: 本文公开了一种在通过喷雾干燥器吸收过程（SDA）处理之前从烟道气流中减少较粗颗粒的量的方法。 该方法包括以下步骤：通过曲线引导含有不同大小的夹带颗粒的烟道气流，从而使颗粒进行离心效应，在设置在外围的颗粒收集装置的主颗粒收集装置 将烟道气分散在粗粒径的颗粒的喷雾干燥器吸收装置的室中，其中原始烟气流的颗粒含量高于20g / Nm 3。 还公开了一种用于执行该方法的装置和气体分散器。 该方法通过消除对SDA上游的颗粒预收集器的需要，大大降低了整个设备处理具有高夹带粗颗粒含量的烟道气的成本。
