Boiler Efficiency and Combustion | Spirax Sarco

Accurate control of the amount of air is essential to boiler efficiency: Too much air will cool the furnace, and carry away useful heat. Too little air and combustion will be incomplete, unburned fuel will be carried over and smoke may be produced. In practice, however, there are a number of difficulties in achieving perfect (stoichiometric

Air Fuel Ratio For A Boiler Results - jcwinternational.be

More often than not, solid fuel systems use too much under-fire air and, co-consequently, do not have an adequate fuel pile in the furnace. When this air/fuel ratio is imbalanced, combustion occurs prematurely which not only reduces efficiency potential, but can also induce damage to the furnace. As solid fuel burns, it goes through a progression.
