Since the exchanger is custom designed,the tube size can be smaller than NPS 1/8 (DN 6 mm) that is the smallest size in Table C.6 in Appendix C,wherein the tube pitch ratio of 1.25 and the diameter ratio of 1.3 can be applied.Design the shell-and-tube heat exchanger.Figure E5.2.1 Shell and tube heat exchanger MathCAD format solution: results for this questionHow does a heat exchanger work?How does a heat exchanger work?Heat exchangers can transfer heat through direct contact with the uid or through indirect ways.They can also be classied on the basis of shell and tube passes,types of bafes,arrange- ment of tubes (Triangular,square etc.) and smooth or bafed surfaces.These are also classied 1Heat Transfer Optimization of Shell-and-Tube Heat results for this questionWhat is the density of a tube heat exchanger?What is the density of a tube heat exchanger?Shell-and tube heat exchangers provide typically the surface area density ranging from 50 to 500 m2/m3and are easily cleaned.The design codes and standards are available in the TEMA (1999)-Tubular Exchanger Manufacturers Association.A simple exchanger,which involves one shell and one pass,is shown in Figure 126.96.36.199 Shell-and-Tube Heat Exchangers
The heat exchanger was used to transfer heat from hot combustion gas on the shell side to the feedstock oil on the tube side.Type and factors that may have caused the return bend bursting are 85K BTU Stainless Steel Pool/Hot Tub Heat Exchanger Ports on opposite sides force the water to flow thru the entire heat exchanger for better heat transfer.2.You do NOT want to use a plate heat exchanger! Plates can clog up,restrict water flow,and unless they are stainless steel can interact with the pool chemicals! Our shell and tube stainless steel construction takes care of these issues! 3.
