In this article we will discuss about the measurement of exhaust gas constituents by two methods: 1. Conventional Method and 2. Modern Methods. The exhaust gas analysis is performed to determine the constituents of various components of gases in the exhaust gas. The analysis is important for determining the air fuel ratio, excess air, combustion products and unburnt components. There [...]
The following article will guide you about how to calculate the calorific value of fuels. Learn about:- 1. Meaning of Calorific Value of Fuels 2. Theoretical Determination of Calorific Value of Fuel 3. Experimental Determination of Calorific Value of a Fuel 4. Determination of Calorific Value of Fuels Using Bomb Calorimeter 5. Calorific Value of Liquid Fuel 6. Calorific Value [...]
In this article we will discuss about the classification or type of fuels: 1. Solid Fuels 2. Liquid Fuels and 3. Gaseous Fuels. The fuel is a material which when once raised to its ignition temperature continues to burn if sufficient oxygen or air is available. The principle constituents of any fuel are carbon and hydrogen. Fuels may be solid, [...]
In this article we will discuss about:- 1. Introduction to Fuel 2. Chemical Equations (Combustion Equations) Involved in Combustion 3. Excess Air Supply for Combustion 4. Mass Fraction and Mole Fraction of Constituents. Introduction to Fuel: The fuel is a material which when once raised to its ignition temperature continues to burn if sufficient oxygen or air is available. The [...]
When the combustion of the fuel takes place, the products of combustion will be carbon dioxide, (sometimes carbon monoxide may also be present) sulphur dioxide, vapour and nitrogen all the while, oxygen also will be present in the flue gases. Generally, the composition of solid or liquid fuels is expressed by weight, whereas that of the gaseous fuels is expressed [...]
In this article we will discuss about how to Calculate calorific value of fuels. Meaning of Calorific Value: The calorific value of a fuel is amount of heat liberated by its complete combustion. For solid and liquid fuels, calorific value is expressed in kJ/kg, whereas for gaseous fuels it is expressed as kJ/m3 where m3 is normal cubic metre measured [...]
