Where is excess steam diverted if there is too much pressure at the gland seal regulator?

When there is too much pressure at the gland seal regulator, excess steam is diverted to the main condenser. This is because the main condenser is designed to handle steam that has been used in the system and to condense it back into water. By directing excess steam to the main condenser, it ensures that pressure within the system remains regulated and prevents potential damage or failure due to overpressure conditions.

The main condenser plays a crucial role in maintaining the efficiency and safety of the steam system by allowing any surplus steam to be cooled and condensed, thus maintaining optimal operating conditions. The condensation process also helps in recycling the condensate back into the boiler system, improving overall efficiency.

In contrast, options such as the auxiliary boiler, atmospheric vent, and steam accumulator serve different functions within the steam system. The auxiliary boiler is typically used for providing additional steam when the main boiler is unable to meet demand. An atmospheric vent serves to release steam to the atmosphere to relieve pressure but is not an ideal solution for managing excess steam in a controlled manner, as it can lead to energy loss. The steam accumulator is designed for storing steam and supplying it when needed but would not be a primary method for venting excess pressure directly.
