1. Is the time it takes for the boiler to dry out the same when there is a disruption in the feedwater to the drum of coal-fired boilers and circulating fluidized bed boilers? 2. Indicate the type of furnace, the steam volume, and then the time required to dry it out
The steam drum level cut-out (LLCO) at the MCR is between one and two minutes when there is no feedwater flow. All steam boilers are equipped with a low-low cut-out, preventing them from being dried out.
