Optimal Combustion Process - Fuels and Excess Air

Even so-called "on-ratio" combustion, used in boilers and high temperature process furnaces incorporates a modest amount of excess air - 10 to 20% more than needed to burn the fuel completely. If insufficient amount of air is supplied to the burner, unburned fuel, soot, smoke, and carbon monoxide are exhausted from the boiler.

What is the Air Fuel Ratio Effect on Combustion Efficiency?

Oct 23, 2013 · The air-to-fuel ratio defines the amount of air needed to burn a specific fuel. The air-to-fuel ratio defines the amount of air needed to burn a specific fuel. The conventional fuels used in the combustion process are oil (#2, 4, and 6), diesel oil, gasoline, natural gas, propane, and wood—ratios for common gases, liquid, and solid fuels noted in Table 1.1 and 1.2.

STOICHIOMETRY OF COMBUSTION

stoichiometry of oxygen/fuel reaction. Stoichiometric air means the minimum air in stoichiometric mixture. The stoichiometric air/fuel ratio (AFR) can be calculated from the reaction equation (g/g). For gas AFR is usually determined in m3/m 3. The actual combustion air depends also on the assumed

Combustion is the conversion of a substance called a fuel into chemical compounds known as products of combustion by combination with an oxidizer. The combustion process is an exothermic chemical reaction, i.e., a reaction that releases energy as it occurs.

Steam-Atomizing and Air-Atomizing Burners

Steam-atomizing burners are simpler and less expensive than the air-atomizing type and are usually used for locomotive and small power plants. They handle commercial grade fuel oils Nos. 4, 5, and 6 and require a steam pressure varying from 75 to 150 psi. The oil pressure needs to be enough to carry oil to the burner tip, usually from 10 to 15 psi.

Stoichiometric Combustion

Stoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).. With unburned components in the exhaust gas such as C, H 2, CO, the combustion process is uncompleted and not stoichiometric .

Combustion Air - an overview | ScienceDirect Topics

L.M. Grillo, in Waste to Energy Conversion Technology, 2013 6.3.4 Combustion air. Combustion air is injected into a furnace as underfire air (below the grate) and overfire air (into the flame above the grate). Generally, 50% to 70% of the total air is underfire air and the remaining portion is overfire air. Most mass burn furnaces operate with between 50% and excess air.

Combustion Basics | CleanBoiler.org

Because air contains a large amount of nitrogen, the required volume of air is much larger than the required volume of oxygen. The nitrogen absorbs some of the heat released in the reaction resulting in a much lower flame temperature compared to a reaction in pure oxygen. Primary air is the air that is mixed with the fuel at or in the burner.

Understanding Combustion Efficiency and Combustion Equations

Because the oxygen is not separated from the air prior to combustion, there is a negative effect on the chemical reaction. Air is primarily nitrogen. While nitrogen is inert, and plays no role in the combustion process, it cools the chemical reaction (burning temperature) and lowers the maximum heat content deliverable by the fuel.
