[Stoves] Testing to determine source of CO

[Frank Shields]

Greetings Stovers,

The question I have is does the CO measured in the stack after the secondary combustion come from Primary Combustion (PC) or Secondary Combustion (SC)? 

As I understand how it works{

We know the primary combustion will produce large organic pyrolysis gases until the internal oxygen and hydrogen is consumed then will switch to releasing heat with added outside oxygen as the solid goes to CO and CO to CO2.

So is the CO found in the stack from CO produced in the PC making its way through the SC or from incomplete combustion of large organic structures not properly prepared for the SC? 

If we were to set up a stove operating and measure the CO in the stack, then introduce CO along with the primary air from a compressed CO tank - would we see an increase in CO in the stack? or is it easily and completely combusted in the secondary? If not seeing any and we kept increasing the CO being delivered how high can we go before seeing ‘break through’? And then if we increased primary air will the CO delivered combust in the combustion chamber increase CO2 in the stack and increase combustion chamber temperature?

Im thinking the CO produced in the PC is very important in controlling combustion chamber temperatures that prepare the complex pyrolysis gases for the SC. 


Im sure this simple experiment must have been done somewhere and wondering what the results are. 

Regards

Frank
