DESCRIPTION:

In most industrial processes including reactors, heat is to be added or extracted to control the process. The addition and removal of heat is done by passing steam or water in a jacket fitted to the outside of the vessel or passing steam or cold water in helical coil inside the vessel. For effective heat transfer and even distribution of heat, the liquid inside is continuously agitated. The present set-up offers us a comparative study of Jacket & Helical coil, which can be operated simultaneously. It is a stainless steel jacketed vessel with helical coil of copper is fitted inside. A variable speed stirrer is fitted in the vessel. Variation in temperature of inside water is measured and is noted. Set-up is fitted with steam traps for condensate collection. Flow rate of water can be controlled and measured using valve and Rotameter. Temperature of inlet and outlet of both hot & cold fluids are measured by temperature sensors.

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.
