Explain why is a vacuum breaker used on shell and tube heat exchangers that are utilizing steam as the heating utility?
Answer Posted / Indu Gahlot
A vacuum breaker is used on shell and tube heat exchangers to prevent the formation of a vacuum within the shell side when steam condensation occurs. A vacuum could lead to collapse of the tubes or damage to the equipment, so the vacuum breaker is used to maintain a minimum pressure in the system.
