Carbon Monoxide Poisoning - Boiler Guide

Carbon monoxide (CO) is a poisonous substance which is produced when organic carbon-based fuels like gas or oil dont burn to completion. Take a boiler for example; when there is insufficient oxygen for all of the gas in the combustion chamber to be burnt carbon monoxide is produced.

What is Flue Gas? - Keison Products

Components of Flue Gas. The components of flue gas are listed below in the order of concentration in the gas. Nitrogen (N2) Nitrogen (N2) is the main component (79 vol.%) of the air we breathe. This colourless odourless tasteless gas plays no part in combustion. It is drawn into the boiler as ballast heated and sent to the stack.
