The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.

Exit flue gas temperature = 200°C. Ambient air temperature = 15°C. Close control of the amount of excess air is possible by the use of oxygen trim control equipment. Such equipment will control the flue gas oxygen content within the range of 2.0–3.0 per cent as compared to the normal 3.0–5.0 per cent.

in combustion flue gases are typically less than 200 PPM, and infra-red spectroscopy is well suited to measuring at these low levels.2 Repeatabilities of better than +/-5 PPM are possible, with low interference from H 2 O and CO 2. Instrument configurations include: - Extractive systems where the flue gases are removed from the

Excess Air. A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.

Therefore, by The flue gases produced from condensing boilers are at a much lower temperatures than those of non boilers.,
