Counter Flow and Parallel Flow Dryer Selection

Counter Flow and Parallel Flow Dryer Selection. Simply stated, thermal rotary dryers are rotating cylinders that continuously bring wet solids into the dryer shell and discharge those solids dried and at a higher temperature. The method of heat transfer is convection or passing heated gas around the solids in the dryer to dry the solids and increase the solids temperature.

Heat Exchanger Flow: Cross flow, Parallel flow, Counter

A double pipe heat exchanger will usually be counterflow, but may also be parallel flow. Car radiators and air conditioner evaporator coils are crossflow heat exchangers. A shell and tube heat exchanger is often approximately counterflow.

Heat Exchanger Principles

Plate heat exchangers. In a cross flow exchanger the cold and the warm air flow perpendicular to each other. In counter flow exchangers the two airstreams flow in opposite direction to one another. The longer the airstreams flow next to each other the better efficiency, which generally makes counter flow more temperature efficient than cross flow

HEAT EXCHANGERS

Figure 1 illustrates an idealized counterflow exchanger in which the two fluids flow parallel to each other but in opposite directions. This type of flow arrangement allows the largest change in temperature of both fluids and is therefore most efficient (where efficiency is the amount of actual heat transferred compared with the theoretical maximum amount of heat that can be transferred).

Co-current drying, which is also referred to as parallel flow, is when the drying air flows in the same direction as the material flow. This immediately puts the wettest material in contact with the hottest combustion gases, resulting in quick initial drying. This system also causes rapid cooling of the drying air, which results in a cooler surface temperature of the dryer shell compared to a counter current dryer
