1 Experiment No: Objective o determine the effectiveness of shell and tube, cross & plate heat exchangers heory A heat exchanger is an equipment which facilitates the of thermal energy between two or more fluids at different temperatures. Heat exchangers are employed in a variety of domestic, commercial, and industrial applications, such as power generation, refrigeration, air conditioning, process industry, manufacturing industry etc. Classification of heat exchangers is presented in Fig..

From the temperature profile (Fig. (b)), it is clear that the temperature difference between the fluid streams decreases from the inlet to the outlet of the heat exchanger. Parallel heat exchangers are rarely employed due to their requirement of large surface area for heat transfer. Examples:Oil heaters, oil coolers, water heaters etc.

Figure shows the schematic and the temperature profile of the fluid streams for such a heat exchanger. he temperature difference between the two fluid streams remains nearly constant (Fig. (b)). Counter heat exchangers provide the maximum heat transfer rate for a given surface area. Hence, they are the most widely used heat exchangers. t c t (emperature) t h Cold fluid Cold fluid t h t h t c temp. (t h ) t c Cold fluid temp.

3 Cross heat exchanger In a cross- heat exchanger, the paths of the two fluid streams through the heat exchanger are usually at right angles to each other. Figure shows a schematic diagram of cross- heat exchanger. he cross heat exchanger in our laboratory is of finned type and the cooling media used is air. Cold fluid (outlet) Baffles (inlet) (outlet) Cold fluid (inlet) Fig. Cross Flow Heat Exchanger Shell & tube heat exchanger his type of heat exchangers has a bundle of tubes enclosed in a shell, usually cylindrical. he tubes are arranged parallel to the shell axis. One fluid stream is passed through the bundle of tubes, while the other fluid stream is s through the shell over the tubes (Fig.). Overall heat transfer between the fluid streams is enhanced by the use of multiple shell & tube passes. With the use of baffles, the shell-side fluid stream is re-routed and made to back-and-forth over the tubes. Plate heat exchanger Plate heat exchangers consist of a number of thin corrugated metal plates arranged together. he fluid streams enter the heat exchanger through frame connections and are then distributed to the plates. he two fluid streams pass through alternate spaces formed between the successive plates. hanks to the corrugations on the metal plates and the small spacing between the plates, the fluid is essentially turbulent which improves the overall heat transfer between the fluid streams. Also, the eddies generated in the clean the heat exchanger surface, thus minimizing fouling. Plate heat exchangers are widely used in industries due to their low cost, easy maintenance, and high thermal efficiency.

C ph = C h = hot fluid capacity rate m c. C pc = C c = Cold fluid capacity rate Maximum possible heat transfer = Q max = C h t h t c or = C c t h t c Q max is the minimum of these two values i. e. Q max = C min t h t c (9) a Rajput, R.K., 007,Engineering hermodynamics, Laxmi Publications, New Delhi.
5 = C h t h t h C min t h t c or (0) = C c t c t c C min t h t c () Determination of overall heat transfer coefficient o determine the overall heat transfer coefficient U for a given heat exchanger, we use the following relation: NU = U A C min () where, NU = Number of ransfer Units Dimensionless W U = Overall heat transfer coefficient m K A = Heat transfer surface area (m ) C min = Minimum of C h or C c (kj/k) In the present study, steam is condensing while passing through the heat exchanger. Hence, C h. hus, the capacity ratio, C r = C min / C max = 0. For such a case, NU can be calculated using the following relationship between ϵ and NU b : NU = ln( ϵ) () Hence, from equations () and (), we have U = C min A ln( ϵ) () b Kays, W.

6 Procedure. Fire the boiler as per instructions in the boiler manual. Wait till it operates satisfactorily at desired and mass rate.. Check the setting of reducing valve (PRV), it should reduce the of steam to around bar, confirm it from the reading of the gauge after the PRV on the main steam header.. Separate inlet and outlet valves for the steam are provided for cross, plate type, and shell & tube heat exchangers. Open the outlet valves first and then the inlet valves for letting steam into the heat exchangers.. In case of cross heat exchanger, measure the air velocity at the inlet to the blower with the help of a digital anemometer.. In case of plate type or shell & tube type heat exchanger, note the water rate to the heat exchanger from the digital display.. Note down the of steam from gauge on steam header. Note the steam rate, temperature of steam at inlet of the heat exchanger, steam condensate and temperature of incoming and outgoing water from the digital display. 7. Vary the air rate (in case of cross heat exchanger) with the help of damper at the inlet of the blower and note down the readings. ake at least - readings in such manner. 8. Vary the water rate (in case of plate and shell & tube heat exchangers) by turning the water inlet valve to the respective heat exchanger and note down the readings. ake at least - readings in such manner. 9. Determine the effectiveness and overall heat transfer coefficient for the three heat exchangers.
