Validated methods for flue gas flow rate calculation with reference to EN 12952-15 -5- 55106284-PGR/R&E 12-7222 EXECUTIVE SUMMARY Operators of combustion plant need to know the flue gas flow rate to calculate the mass release of pollutant emissions.
Jun 15, 1994 · The liquid-to-gas ratio of the FGD is approximately 94 gallons per 1,000 acf and the reagent ratio is approximately 1.15 moles of reagent, CACO3 in the limestone, per mole of SO2. Only fresh limestone is used; therefore, there is no reagent recycling. The FGD system is approximately 70 to 90 percent efficient. 2.2.3 Particulate Control
The Alternative Control Techniques (ACT) document for NOx emissions from utility boilers, maximum SNCR performance was estimated to range from 25 to 40 percent for natural gas-fired boilers.12 Performance data available from several natural gas fired utility boilers with SNCR

release of pollutant emissions. For many standard fuels, the calculation of flue gas flow rate gives reliable results, with a defined uncertainty, using relatively simple procedures. The calculated dry flue gas volume is combined with emission concentrations that are reported on a dry basis.

Feb 23, 2010 · When the biomass boiler is in operation at its design load with a flue gas O 2 concentration of 6%, the dry flue gas flow rate was estimated to be ∼550 l (at 15°C and 1 atm)/min. The amount of CO and NO x emitted when the boiler is actually in operation could be estimated by using the measured emission concentrations and the estimated dry flue gas flue flow rate. However, as discussed earlier, the boiler …

Flue Gas Recirculation. Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature and reduce NOx formation.
