Boiler Efficiency | Kane International Limited

Boiler Efficiency. The objective of a boiler is to burn the hydrogen contained in the fuel with oxygen from the atmosphere to produce heat. Combustion efficiency analysers exploit the fact that by knowing the fuel (and its chemical composition) and measuring the flue gas temperature and either the oxygen or carbon dioxide level the efficiency of the boiler can be calculated.

The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4- pass will have higher efficiency and lower fuel cost. This is not an opinion; it is basic heat exchanger physics.

Combustion Efficiency and Excess Air - Engineering ToolBox

Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide - CO 2 - after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.

Boiler Efficiency: Introduction and Methods of Calculation

Combustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.

How to Calculate the Stoichiometric Air-fuel Ratio

The stoichiometric air-fuel ratio is an important parameter of fuels. When designing an engine for a particular fuel, it's important to know how much air is needed to completely burn a certain amount of fuel. This article describes this ratio and presents an easy way to calculate it when the composition of a fuel is known. How air-fuel ratio can be diagnosed and monitored with the help of air
