Stoichiometric Air or Theoretical Air Quantity: Calculation …
Coal is the most widely used fuel source used to produce Electricity. Air provides the necessary Oxygen for burning coal. It is the chemical reaction between Carbon in coal and the Oxygen in the air that produces the heat energy. The most important requirement to burn coal is the correct quantity of air. The method of calculating the air quantity is explained in this article. The Heating value

Gas constant - Wikipedia
The gas constant (also known as the molar, universal, or ideal gas constant) is denoted by the syol R or R.It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure–volume product, rather …
Calorific value (CV) | National Grid Gas
Process gas chromatographs separate natural gas into its constituent compounds (i.e. methane, ethane, carbon dioxide, etc.) and measures the amount of each in the gas. The physical characteristics of each component, as defined by ISO 6976, are programmed into the chromatograph and an overall CV is derived from the measured composition.

Steam Heating Process - Load Calculating
In general steam heating is used to change a product or fluid temperature maintain a product or fluid temperature A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).
