Heat exchanger selection calculation
Thread Content
HTRI is responsible for the selection and design of the heat exchanger; the circulating water flows through the shell side of the heat exchanger at a flow rate of only 0.2 m/s. How can this flow rate be increased? By reducing the diameter, the flow rate of the circulating water remains more or less unchanged, but the flow rate of the high-temperature syngas in the tube side increases. Is it possible to increase the flow rate of the circulating water?
The shell side diameter can be changed, as well as the baffle parameters; the fouling thermal resistance can also be adjusted
Changing the shell diameter, as well as the tube spacing (number of tubes), can increase the flow rate
Reduce the baffle spacing and baffle openings
