A Number of Genetic Lineages Can Be Created from the Above Data

 

Using decisive classification rather than theoretical the practice is not to make a big distinction between single gas and multi gas analyzers. Therefore the genetic lineage by gas type could be:

 

Source Gas Analyzers by Pollutant for Power Plants

 

Genetic Base Class

Aliases

Cousins

CO

 

 

CO2

 

 

Direct Methane

 

 

H2S

 

 

HCl

 

 

Multi gas

 

FTIR multi gas,  NDIR multi gas

NH3

 

 

NOx

 

NO,NO2

SO2

 

 

*THC

Total hydrocarbon

 

*TRS

 

 

 

*For non-utility applications these two pollutants plus O3, BTX, VOC and other pollutants may be continuously analyzed.

 

There is a genetic lineage for Monitoring Acquisition Method, which is shown in Figure 1.

 

There is also a genetic lineage by Principle of Operation, which is shown in Figure 2.

 

Here is one final example to integrate the foster and genetic family. The following shows the most popular SO2 CEM for power plants.

 

Electric Utilities -coal-fired boilers – air quality - FGD

 

Optimization & Instrumentation

Gas Monitoring

CEMS

SO2 - Dilution Extractive

 

--fluorescence -- sources

 

In this case there is a lack of clarity relative to the principle of operation. There needs to be some input and consensus from the industry as to how to clearly classify the principles based on actual use not theory. Once there is consensus in English it will be a much simpler task to prepare the Chinese equivalent.

 

We invite the subscribers to this newsletter to weigh in on any aspect of this endeavor.
