What can cause insufficient steam supply if air vents are malfunctioning?

If air vents are malfunctioning, passing steam can cause insufficient steam supply because trapped air can accumulate in the steam system. Air vents are designed to allow air to escape from the system, and if they do not function properly, this can create air pockets. These pockets of air interfere with the flow of steam, leading to a situation where the effective heating capacity of the system is compromised.

When steam cannot move freely due to the presence of air, it cannot reach the desired areas of the system, resulting in inadequate steam supply. Proper management of steam and air is crucial for efficient heating and operation in a steam system, and failure of air vents disrupts this balance.
