What happens if economizer trips in boiler?

If an economizer trips in a boiler system, it typically results in a shutdown of the economizer, which can lead to reduced energy efficiency and increased fuel consumption as the heat recovery process is interrupted. This may cause the boiler to operate at a higher temperature and pressure to compensate for the lost heat recovery, potentially triggering safety alarms and system protective measures. Additionally, the trip may lead to a decrease in steam production and could impact overall plant operations, necessitating immediate investigation and remedial actions to restore normal function.
