Each of these parameters vastly overwhelms any consideration of molecular weight.” Similarly, the measurements you observe also depend on those parameters.
Wow, once again, excellent post.
My questioning comes not from CO alarm placement but from what I've viewed occurring during the combustion process with a combustion analyzer and my own eyes.
This leads me to think that what I am seeing is more of a timing issue than an air mixing issue.
Have to admit it has me wondering if the CO2 is spilling at a greater rate than it can mix with the ambient air and be dispersed evenly.
Would be interested in your thoughts on this.
