A question regarding the analysis of coke oven exhaust gases
Thread Content
Analysis of coke oven exhaust gases, using chemical absorption to obtain the data: carbon dioxide levels are 6.5, oxygen levels are also 6.5, and carbon monoxide levels are 0.8. The oxygen content seems a bit high; are these numbers incorrect? Does anyone know something about this?
Where is the location for gas sampling? At the location of the main flue flap, the oxygen content is around 6–7%! !
Samples were taken from the furnace top vertical flue; an upward airflow was present.
Samples are taken from the fire viewing hole, right? At the fire viewing hole in the rising flue, is that correct? If it’s oxygen content, it’s definitely high
The data collected daily shows basically no difference
