## Heat loss estimate for plume rise of flue gas

## Heat loss estimate for plume rise of flue gas

(OP)

Hi,

I hope you can help me with the following problem.

---------------

A large natural gas fired power plant producing 300 GW of power releases sulfur dioxide(S02) during its operation. The S02 is released from a 40 m stack at a rate of 20 g/min. The average wind speed is 12 m/s, with strong solar radiation. What is the distance downwind of the plume centerline emission point at which the predicted 502 ground-level concentration falls to about 2 ug/m3?

---------------

I have the equations for Gaussian modeling of the concentration plume distribution and the stability class parameters. My question is how to estimate the plume rise and finally calculate the effective stack height. With no information about flue gas temperature or other, I think I should use the power produced by the plant to estimate the heat loss in dry flue gas and therefore the plume rise, but couldn't find any satisfactory relation.

Any ideas on how to work with the given data?

Thanks so much!

This is actually an exercise as part of an engineering test, so the use of simulators is not an option. The iteration is supposed to be by hand and I have the equations and constants for that, but not much data (other than what I posted) to estimate the plume rise.
