Flue Gas - an overview | ScienceDirect Topics

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.

Alfa Laval - Waste heat recovery

Alfa Laval Aalborg offers a series of highly efficient waste heat recovery boilers that extract heat from hot flue gases and generate steam or hot water. A boiler is easily added to your flue gas stream and recovers heat that would normally be released into the air through a chimney. There are many possibilities to profit from recovered heat.

improve your boiler’s combustion efficiency

Improve Your Boiler’s Combustion Efficiency

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

understanding boiler stack losses - leaders in steam

Understanding Boiler Stack Losses - Leaders in Steam

A common trend observed is, as boiler is operated continuously, the measured outlet temperature of flue gases increases. After operation for a few months, significant rise in flue gas temperature and hence stack losses is observed. The reason behind this is, as a boiler is operated, scales are formed on the boiler tubes.
