Boiler Efficiency - an overview | ScienceDirect Topi

The three main factors in determining efficiency are therefore flue-gas exit temperature, excess air and burnout, all of which are dependent on the technology. The flue-gas exit temperature is related to boiler design rather than the combustor. A well-designed boiler can achieve low exit gas temperatures for any of the technologies.
