SIM 3220 Shell and Tube Heat Exchanger

Model Description

The heat exchanger is used to heat cold fuel gas from a choice of 2 different supplies with variable temperatures, by transferring heat from a hot oil supply.

The model has two pages; one showing a typical feed- back control system and one showing a typical feed-forward control system.

On each of the heat exchangers the heat transfer co-efficient and the heat exchange area of the heat exchanger can be altered.

The feed supply of fuel gas can be varied using hand valves.

The flow of hot oil is controlled by either the feed-forward or feed-back control loop.
