Duct Network Flow and Temperature Balance

Situation: Branching duct system feeding primary (hot) and tempering (cold) air to coal pulverizers.

Problem: Imbalanced air flow rates and temperatures between pulverizers.

Solution: System resistance model calculates losses and temperatures throughout duct network. Provides optimal flow damper settings to meet flow rate, pulverizer inlet temperature, and overall pressure loss objectives.
