Parallel and Counter Flow Designs Heat …

The most common arrangements for flow paths within a heat exchanger are counter-flow and parallel flow. A counter-flow heat exchanger is one in which the direction of the flow of one of the working fluids is opposite to the direction to the flow of the other fluid. In a parallel flow exchanger, both fluids in the heat exchanger flow in the same …

Why is a counter flow heat exchanger better than …

Hence the area for counter flow heat exchanger will be LESS compared to parallel flow heat exchanger. Thus more effecient. Thus more effecient. 2) The highest ideal effectiveness achieved in case of counter flow heat exchanger is 100% while for parallel flow is only 50%.

Or, said another way, more heat has been removed from the dryer gas flow and imparted to the solids in a counter flow dryer than a parallel flow dryer. Proof of the efficiency of the dryer is the gas temperature at the discharge gas end of the dryer; the lower the temperatuer the more efficient the dryer.
