Alken Even-Flo® formulas inhibit reaction (2), by allowing for efficient combustion with less "excess air." As predicted by the law of mass action, reducing the amount of oxygen in the combustion zone retards the oxidation of sulfur dioxide to sulfur trioxide. Second, the improved combustion promoted by Alken Even-Flo® formulas reduce the number of soot particles in the combustion zone which might otherwise act as adsorption/reaction sites for the catalytic oxidation of the dioxide to trioxide.
Please note that Alken Even-Flo® does NOT reduce the total amount of sulfur oxide in the stack gas. As Alken Even-Flo® reduces the amount of trioxide formed, the amount of dioxide increases slightly.
Both nitrogen and oxygen are reduced when lower excess air is employed, thus nitrogen oxides are also reduced. This reaction is known as the law of mass action. A lower flame temperature, which usually results when excess air is lowered, also contributes to the reduction of nitrogen oxide. Alken Even-Flo® contributes improved atomization which allows more efficient combustion despite lower excess air.
Alken Even-Flo® reduces "dust" volume by reducing soot, or incompletely-burned oil by atomizing the oil into smaller particles, which burn more quickly and completely than larger particles.
