Validated methods for flue gas flow rate calculation with reference to
Stack Flow Rate Calculations • Calculation Stack gas velocity, V s V s = K pC p [Δp T s(abs)/ P s M s]1/2 = 5130x0.84[0.3087x612/29.78/ 27.12]1/2 = 2084 act ft/min With the values from the previous slide, the stack gas velocity, Vs, is calculated using the presented equation. The calculation results in a stack gas velocity of 2084 actual feet per minute.
Evaluating the Use of CEMS for Accurate - POWER Magazine
rect approach is introduced for determining SO2 emission based on elemental balance of combustion processes and SO2/CO2 relations. Our objective was to develop and test a methodology applicable to the determination of SO2 emis-sion from stationary combustion sources. The indirect method will increase accuracy by minimizing field sam-
In practice, the actual emissions are somewhat lower due to the fact that part of the SO2 is converted into Sulphates (basically of calcium) and part into SO3. The calculation thus represents the maximum emission of Sulphur in the form of SO2. 3. The emissions data refer to the Reference % O2, in accordance with the legislation

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.
