Human Error: Inadvertent Primary Boiler Shutdown
$150,000 capital investment for new boiler.
A non-functioning backup boiler can continue undetected for a long time because the first system is picking up the entire load. However, this will eventually cause the first system to fail and lead to an emergency maintenance situation.
In addition, even though there is a safety cutoff switch to ensure that the boiler stops running if there’s no water, full ramp up and emergency shutoff puts unnecessary strain on the system and reduces its useful life.
Despite the safety mechanism, there is a serious safety hazard with running a dry boiler. Adding cold water to a dry, hot boiler can lead to boiler explosions. No operator should depend on the emergency safety mechanism to avoid this catastrophe.
