(E) Stack Height Requirement. Each boiler authorized under this standard permit shall have a stack with a minimum height as determined by the following equation: H = 0.04 Q + 8.20 Where: H = Minimum stack height above ground level in feet (ft) Q = Maximum boiler …
Mar 01, 2010 · Nevertheless, the stack height determined by the Memorandum will normally be sufficient for condensing boilers with low NOx burners (<0.02g/MJ) with thermal input less than 1 MW burning very low sulphur fuels and discharging above roof level. Larger boilers will require more detailed assessment, using an appropriate dispersion model.
Nov 24, 2011 · Stack height for boilers may be calculated as per the following formula: H = 14 * (SO 2 in flue gas in kg / h) 0.3 where: H = height of stack in meters If the fuel consumption is A kg/h and sulphur content in fuel is x% then 1 kg of fuel will give 2x% SO 2 Thus the term in …
Stack height requirement based on sulphur dioxide emissions by using the equation - stack height = 14 (Q) 0.3 [where, Q is the emission rate of SO2 in kg/hr] By using simple Gaussian plume model to maintain ambient air quality requirements for all concerned parameters, in the receiving environment.

7. Stack Size – Pressure drops through the boiler exhaust system should be calculated and in general should not exceed 0.2″ WC. Undersized stacks create excess back pressure on the boiler resulting in combustion problems, inability to make full capacity, or both. There are several very competent manufacturers of boiler exhaust systems.
