Corrosion in Heat Exchangers

Some of the criteria for selecting materials used for awakeing plant exchangers be corrosion resistance, strength, heat conduction, and cost. Corrosion resistance is oft a problematic criterion to meet. Damage to heat exchangers is frequently difficult to avoid.                   There are many variables related to specifying heat exchangers -- for example, temperatures, stop rates, pressure drop and heat remove -- that are special K to all types. There as well are many variables that are specific to specifying a plate heat exchang er -- 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 sustain among plates and get ahead turbulence, which gives the plate heat exchanger its richly heat transfer. ·         Gaskets. The wrought elastomeric gaskets on the plates ensure that the come transmit are pixilated securely from each other, preventing cross-contamination. The gaskets also stipulate the direction of flow within the exchanger.

· !         Frame. The snare provides structural support and pressure containment by enclosing the plate pack. The main frame components consist of a fixed end, a transferable end, upper berth 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 baptistry 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 fiber concept - employ corrugated plates for heat transfer - was introduced in...
