Review of Stoichiometric Technique for Better Performance of the Boiler
Keywords:Boiler, Combustion, Air fuel ratio, Fuel, Oxygen Control
The combustion within the boiler burns fuel to create heat energy which then produces electrical power. The combustion of fuel is its reaction with oxygen available in the air. The amount of fuel that can be well burnt is limited by the quantity of oxygen. Once all the fuel is not burnt at all, some of it stays in the boiler and other quantity goes to the atmosphere. Most of the fuels used in the boiler are hydrocarbons which release hydrogen and carbon as residuals. It causes small efficiency and degradation of the air. It is needed to take the faction of air/fuel to the optimum value to reduce these problems. This paper provides different reviewed algorithms that control the combustion within the boiler and the role of environmental temperature. The author found that the separation of the oxygen from the air combined with the preheating both fuel and oxygen taking into account environmental temperature would provide better stoichiometric values, which improve the performance.
