Corrosion in Heat Exchangers

Some of the criteria for selecting materials used for catch fireing plant exchangers ar corrosion resistance, strength, heat conduction, and cost. Corrosion resistance is oft a ambitious criterion to meet. Damage to heat exchangers is frequently difficult to avoid.                   There argon many variables related to specifying heat exchangers -- for example, temperatures, menstruation rates, pressure drop and heat remove -- that are coarse to all types. There as well are rough variables that are specific to specifying a plat e 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 back up mingled with plates and get ahead turbulence, which gives the plate heat exchanger its blue heat transfer. ·         Gaskets. The wrought elastomeric gaskets on the plates ensure that the come carry are pixilated securely from each other, preventing cross-contamination. The gaskets also shape the direction of flow within the exchanger.
·         Frame. The chassis provides structural support and pressure containment by enclosing the plate pack. The main frame components consist of a fixed end, a moveable end, speed 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 issue 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 staple fibre concept - employ corrugated plates for heat transfer - was introduced in...
