how to calculate how the boiler flue gas is calculated

Industrial Boiler Efficiency Calculation & Factors

Air Flow Rate Calculation (Flue Exhaust Gases). 1 volume of gas requires So 12.5 times the gas volume are approx exhausted from the chimney. Example,. 1,000 kW boiler operating at 90% efficiency gives burner firing rate of 1,099 kW.

If the concentration in the wet flue gas is required then the water content has to be included in the above calculation. C + O2 = CO2 2H 2 + O2 = 2H 2O Oxygen required for stoichiometric combustion = 4.33+1.6−1.3 = 4.63kg-mol Air requirement = [4.63×100 ×22.41]/[21]= 494.1 m3 at NTP Appendix A: Calculation of Flue Gas Composition © The Author(s) 2014

Validated methods for flue gas flow rate calculation with

analyses. The calculated flue gas flow is compared with the reference flue gas flow calculated from the elemental composition. It is shown that, for a wide range of coal and biomass compositions, the above formula performs very well. For light fuel oil the formula is: V God = 1.76435 + 0.20060 H (N) (m 3/kg) and for natural gas: V God

Calculating Flue Gas Temperature

In large boilers usually only carbon monoxide can be found in significant amounts in flue gases. Assuming that flue gases contain only these two gases, the losses [kW]can be calculated as: φ L1 = m& CO ⋅ H l,CO + m& H 2 ⋅ H l, H 2 (9) where m& CO is the mass flow of carbon monoxide [kg/s], m& H 2 the mass flow of hydrogen, H l,CO the

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various fuels.
