Control of Particulates
Settling Chambers
8 The simplest devices for controlling particulates are settling chambers .
9 These are nothing more than wide places in the exhaust flue where larger particles can settle out of the exhaust gas stream.
10 They are usually equipped with a baffle to slow the gas stream.
Obviously,only very large particulates(>100um) can be efficiently removed in settling chambers.

参考答案:微粒控制
沉积室
8 控制微粒的最简单设备是沉积室
9 仅仅是排气通道中的一些宽阔区域，较大的微粒会在其中沉积，这样排出的气体中就只有较小微粒了。
10 通常配有挡板以降低气流速度
很明显，只有非常大的微粒（>100um)可以被有效的从沉积室中清除。
