: I could use some clarification which gasses we should requiring our combustion analyzer to monitor and why. In the past we had used a COSA 6000 HC. We are considering the purchase of additional combustion analyzers but were uncertain what gas sensors we really needed. Along with flue gas temperature, room temperature and draft, is just the O2, oxygen and CO, carbon monoxide adequate to set up and adjust gas and oil fired burners for most boilers. With the analyzer fitted with optional sensors the price varies a great deal. We should only get what we need. Would any of the following gas sensors be needed as well and why. NO for nitric oxide, NO2 for nitrogen dioxide, SO2 for sulfur dioxide, CH4 for methane and H2S for hydrogen sulfide. Is the NOx a reading of a combination of gasses. What is low NOx. Is this an EPA emission standard. When would it apply. Any help in this area would be greatly appeciated. Thank you.
you need to contact your local enviromental office, emission standards vary from state to state and in some locations county to county. In my state NOx is still not a major concern but in neighboring states they have strict guidelines to NOx. CO, CO2, and temps should be adequite for a fairly good tuneup.
