Corrosion in Heat Exchangers

wearing away in Heat Exchangers Table of Contents Introduction.........................................................3 Corrosion Problems..............................................6 References.........................................................15 Section 1 Introduction Heat exchangers atomic second 18 jetly used to tape drive estrus from steam, water, or gases, to gases, or liquids. Some of the criteria for selecting materials used for hot uping plant exchangers argon corrosion resistance, strength, heat conduction, and cost. Corrosion resistance is oft a unenviable criterion to meet. Damage to heat exchangers is frequently difficult to avoid.                   There are many variables related to specifying heat exchangers -- for example, temperatures, period of time rates, pressure drop and heat remove -- that are car park to all types. There as well are nigh 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 living mingled with plates and get ahead turbulence, which gives the plate heat exchanger its high 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 mildew the direction of flow within the exchanger. ·         Frame. The ashes provides structural support and pressure containment by enclosing the plate pack. The main frame components consist of a fixed end, a negotiable end, fastness and lower carrying bars, and fasten bolts. ·         Connections. The connections for incoming and outgoi ng media usually are found in the fixed end ! plate. In the eccentric 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 fundamental concept - employ corrugated plates for heat transfer - was introduced in...
