As hydrogen, acetylene, oxygen, methane, etc. The volume the volume of hot air reduces on cooling volumetric efficiency required of these compressed gases is very high so it is required increases. For this reason intercoolers are used. Intercoolers can be placed higher energy consumption by 1 percent to achieve equivalent horizontally or vertically but horizontal intercoolers htri design manual pdf free download more output.
Thus lower the temperature of intake air, more is the effective thus horizontal intercoolers generally used. Intercoolers are generally placed in between two stages of II. Thus volume of fluid decreases which Problem identification increases the volumetric capacity and decreases the work done by motor. It is simple in construction To cool down the air from Thermal design of heat and easy to clean as it has floating rare end head thus tube sheet exchanger based on the input parameters which are given in the can be easily removed for cleaning.
Tube and tube layout the overall heat transfer coefficient also, finding out the acceptability of the pressure drop. The enough tube thickness ensures that it will bear the internal pressure along with the adequate corrosion allowance. Stainless steel, copper, bronze and alloys according to the Kern's method. It is simple to apply, accurate of copper- nickel are the commonly used tube materials. The selection criteria for The shortest center to center distance between the adjacent the heat exchanger, design procedure and its calculations are tubes is Pitch.
The general pattern of tubes is square or discussed in the subsequent sections Selection Criteria for Shell triangular pattern. The tube count is the number of tubes that and Tube Heat Exchanger can be accommodated in a given shell ID. Shell: 3. No of passes Shell is the cylindrical vessel container through which To obtain greater heat transfer co-efficient and also to fluid flows and the tube bundle is placed inside the shell.
The tube passes vary from 1 satisfactory corrosion allowance. A single tube pass is selected for the design. Baffle Liquid is maintained in a state of turbulence ensures the higher heat transfer coefficients. The turbulence is induced outside the tubes which cause the liquid to flow at right angles to the axes of the tubes.
This causes considerable turbulence even when a small amount of liquid flows through the shell. One from the various types of baffles is used to increase the fluid velocity by diverting the flow across htri design manual pdf free download tube bundle to obtain higher transfer co-efficient. The distance Between adjacent baffles is called baffle-spacing. The segmental baffle used in design shown in the figure Shell side 3. Drop By Vendor Shell side 0. Baffle Plates C. Heads C.
High Del Del Tube Side Calculations E. The parameter which will be verifies is на этой странице overall heat transfer input parameters are taken from specification sheet. The values coefficient, heat duty and pressure drop. HTRI software is used to verify analytical thermal design.
It gaves close results as that of obtain from thermal design. The comparision between calculated values and software obtained values concludes the varification of the parameters.
The proven theoretical methods are in good agreement with the software results. It can load a case from CD or a read only directory. If a user loads a case marked as read only, HTRI opens and runs the case. The results are given by the software are in less time as compared to manual calculations. HTRI can estimate the shell weight. It has an approximation procedure for estimating the weight. It does not rigorously determine the material needed to construct the shell but rather divides the diameter into suitable portions.
The values obtained are reasonable but not exact Thus after all the input is put in the software, htri design manual pdf free download generates the results which can further be used for analyzing them with required output.
If found satisfactory user may move ahead with the design or he shall again change the htri design manual pdf free download values and obtain the required results.
