Witrynaimpinger train or ice-cooled condenser, followed by a sealed pump controlled by valves Vi and V2 for coarse and fine flow adjustment, respectively. From thi s point, the ga in a standard isokin-etic sampling train would pass directly to the dry gas meter and sample orifice and finally be exhausted. In the train as modified for emission gas ... WitrynaIt was found that NOx could be collected efficiently (99%) at sample flow rates of 1 L/min over 20- to 40-min sampling periods at the NOx levels encountered in modern utility boilers. The removal of the stack gas moisture by use of an impinger train or condenser ahead of the sample train was shown to be necessary for efficient NOx collection.
Witryna2.4.2.2 Preparation of collection train – As discussed in Section 2.2.1.2, the first midget impinger in this train is empty. Measure approximately 20 mL of DI water into the second impinger and connect the probe, impingers, rotameter, critical orifice, and pump as shown in Figure 1. An unheated filter is included upstream of the rotameter if the WitrynaThe in-stack method train was based on EPA Preliminary Method PRE- 004, which includes in-stack PM10 and PM2.5 cyclones, an in-stack 47 mm quartz filter, and an EPA Method 202 impinger train for ...
