Streamline flow through R.H.S duct and funnel before modifications
Source publication
In the present era Government has placed strict emission norms for industries. Power
plants have adopted addition of additives like ammonia dosing etc for emission control. But
this results in increased load in the draught system which cannot be met by the existing
induced draught fans as they are already overloaded. The most economical solution of...

Context 1
... computational results obtained on analysis on the right part of the duct were interpreted as discussed below. Figure-3 (a) is a streamline plot showing flow through the RHS duct before modification. The figure depicts eddy formation when the flues gases flow through the duct. ...

... are then found to occur till the outlet of the duct. Figure-3 (b) is a streamline plot (side-view) for flow through the funnel of RHS duct. It can be seen that the flue gases flow more through the bottom zone of the funnel. ...
Context 3
... erosion on the duct walls in the above zones is mainly due to the eddy formation. It can be observed from the streamline plot in Figure-3 that the velocity is between 18 m/sec to 20 m/sec on the duct walls due to these eddies. This increases the ash particle impingement on the duct walls and hence the erosion. ...
