Gas Stack Exit Velocity

May 19, 2010· I'd like people's opinions on what the minimum design velocity of flue gas should be from the gas stack In the past I have used numbers between 50 and 60ft/s I did a search online and saw a minimum of 16ft/s I checked B&W Steam and it said that the 'typical' was 30-35ft/s...

Performance study and application of new coal

The recovery of heat from the flue gas is an effective way to improve the thermal efficiency of a boiler In a coal-fired boiler with wet-desulphurization, a portion of the flue gas thermal energy is used for the latent heat process, which leads to temperature reduction and humidity increase...
