Hydrogen Gas Analyzers | Nova Gas | H2 Analyzers

In some cases, the sample is comprised of a simple mixture of hydrogen and one other gas such as nitrogen (N2), air, CO2, etc. A binary mixture will not have the same interference problems that the complex mixtures have. We can treat this situation as shown below. When the non-H2 gas comprises of the mixture, the H2 reading is 0%.

Why Economizer and Air Pre-Heaters are Provided in Boilers

May 03, 2009 · Boilers are provided with economizer and air pre-heaters to recover heat from the flue gases. Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters. If economizer alone is provided then the efficiency will be lower by 12 % when compared …

Stoichiometric Combustion - Engineering ToolBox

Stoichiometric combustion and excess of air. 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

Heat of combustion - Wikipedia

The higher heating value takes into account the latent heat of vaporization of water in the combustion products, and is useful in calculating heating values for fuels where condensation of the reaction products is practical (e.g., in a gas-fired boiler used for space heat). In other words, HHV assumes all the water component is in liquid state
