### Velocity of gases in a flue / stack | Physics Forums

30/7/2016· Think of the chimney just starting to draw. There is stationary air at ambient pressure in the chimney. Hot air is introduced in the bottom. It begins to rise due to buoyancy. As it rises it creates a low pressure below it that draws more hot gases in. The rising gas ...Velocity Calculation - E Instruments InternationalM is the molecular weight of the stack gas on a wet basis in g/g mole. To calculate this value the component of the stack gas must be known. In general the main components are CO 2, O 2 and N 2 plus water.

### Evidence from 3D seismic tomography for hydrate .

The highest anomalous velocities appear in a zone of about 150 m above the top of a gas-rich layer. Unless carbonate has been preserved in layers at hundreds of meters beneath the present seafloor, the depth extent of the anomalous velocity zone makes it more likely to be explained by the occurrence of gas hydrates in the flanks and interior of the chimney.Flue-gas desulfurization - WikipediaFlue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration.
