Default Why would a gas boiler make soot?

The gas pressure needs to be checked first, if it is low the gas and

Aah - the gas / fuel mixture


No chance of any carbon monoxide there


Just from first principles (no specific knowledge):


soot implies incomplete combustion


incomplete combustion can give CO


e.g. *4CH4 + 6O2 - C + 2CO + CO2 + 8H2O


It would if it was a gas / air mixture ...

Which is why they use a CO/CO2 meter, a Telegan for example

not really come across an oxygen meter in general use for measuring
combustion efficiency

Co2 meters were used in days of yore for measuring purely carbon
fuels ie coal.


No - co / co2 meters - measuring the ratio

As there is much less carbon in gas,


Would you like to expand on that ?

Do you really understand what you're talking about?

they are much less accurate which
is why oxygen analysers came in and are preferable.


Not amongst your average jobbin' fitter they aren't
