Corrosion in Heat Exchangers

Some of the criteria for selecting materials used for stir uping plant exchangers atomic number 18 corrosion resistance, strength, heat conduction, and cost. Corrosion resistance is oft a rough criterion to meet. Damage to heat exchangers is frequently difficult to avoid.                   There argon many variables related to specifying heat exchangers -- for example, temperatures, flow rate rates, pressure drop and heat remove -- that are general to all types. There as well are round variables that are specific to specifying a plate heat exchanger -- in particular, the number of passes. The main components of the plate heat exchanger include: ·         Plate Pack. The plate pack is composed of a number of corrugated heat transfer plates according to the heat transfer surface required. The plate corrugations provide patronise in the midst of plates and get ahead turbulence, which gives the plate heat exchanger its soaring heat transfer. ·         Gaskets. The wrought elastomeric gaskets on the plates ensure that the come convey are pixilated securely from each other, preventing cross-contamination. The gaskets also throttle the direction of flow within the exchanger.

·!         Frame. The order provides structural support and pressure containment by enclosing the plate pack. The main frame components consist of a fixed end, a movable end, velocity and lower carrying bars, and fasten bolts. ·         Connections. The connections for incoming and outgoing media usually are found in the fixed end plate. In the subject field of a multiple-pass design, connections also are found on the movable end. The plate heat exchanger is well known as one of the nearly efficient heat exchanger designs. Its radical concept - employ corrugated plates for heat transfer - was introduced in...
