Measurement of O2 Concentration in Exhaust Gases …

Unlike oil, coal and gas produce a large quantity of ashes when it is burned, necessitating pulverized coal-fired boilers to be equipped with an ash removal system such as a cyclone. Exhaust gases from these boilers contain a large quantity of dust (10 to 30 g/Nm3) and flow very fast as the result of the large volume of air being blown into the boiler.

A gas consisting mainly of CO 2 and water vapour is generated, with a concentration of CO 2 between 70% and 90%, depending on recycle mode (wet or dry). The recycled flue gas is used to control flame temperature and make up the volume of the missing N 2 to ensure that there is enough gas to carry the heat through the boiler.
