CFD application for coal/air balancing in power plants

Theclean air flowwould, therefore, bebalancedbut the correspondingcoal/air flowwould still be unbalanced. In one instance, it was reported that after theclean air flowwasbalancedto within 3%, thecoal/air flowwas still unbalanced by 27% . On the other hand, if the orifice sizing is based on thecoal/air flow balancing, the correspondingclean air flowwould be unbalanced.

Trace Element Mass Flow Rates fromU.S.CoalFired Power
Trace Element Mass Flow Rates fromU.S.CoalFired Power

Trace elements (TEs) exitcoal-fired power plants (CFPPs) via solid, liquid, and gaseous waste streams. Estimating the TE concentrations of these waste streams is essential to selecting pollution controls and estimating emission reduction benefits. This work introduces a generalizable massbalancemodel for estimating TE massflowrates in CFPP waste streams and evaluates model accuracy for ...

The PlugFlowReactor (PFR) is used to model the chemical transformation of compounds as they are transported in ``pipes.'' The ``pipe'' may represent a river, a region between two mountain ranges through whichairflows, or a variety of other conduits through which liquids or gasesflow. Of course, it can even represent apipe.
