boiler flue gas analysis
boiler flue gas analysis
(OP)
We were given an analysis of flue gas exiting a recovery boiler. The dust makeup was reported in percent volume values. However, no total volume or any other information was given. How can I figure out the specifc gravity of the material? I tried using the densities of each individual species, however, that resulted with an SG of 2.16. The gravity of this material should be in the range of .8 - 1.2. Was I going at this incorrectly? Or, could it be the analysis was incorrect? Thanks for your help.

RE: boiler flue gas analysis
If yes, answer is this:
(SG)flue gas ={SGa*(vol. per.)a +
SGb*(vol. per.)b + ...}/100
But if your question is another,please write your analysis report and your interesting parameter(with a ? )

Sometimes, the data is reported referred on a specific value of oxigen and temperature. It's also necesary to know if it's the case.
I can calculate for you the density with data refered or I can give you the way you can calculate it.
The gases like CO (Carbon Monoxide), CO2 (Carbon Dioxide), SO2 (Sulphur dioxide), NOx(Nitrogen Oxide), etc. are expresed in concentration units based on volume or weight.
But dust concentration is generally expressed as a density because the isokinetic analysis used for this determination is based on the weight of dust collection and volume of gas measured.
The concentration of pollutants is referred to a normal conditions (15.5 °C, 10130 Pa) or Standard Conditions (0 °C 10130 Pa) and a rate of oxygen like 5% depending on the standar or the rule to be aplied.
