Guide to Steam Systems Part 1 Steam Generation

Overloading the boiler beyond its MCR, results at best, in carryover of boiler water into the steam space and at worst burner lockout with resultant loss of steam. Poor quality steam impacts on process heat transfer surfaces, reducing plant efficiency whereas boiler lockout results in loss of steam with loss of production time and product wastage.

What is Carryover | Causes of Carryover

Operating the boiler at pressures significantly lower than design pressures is a cause of carryover. Lower the steam pressure more will be the specific volume of the steam inside. Hence, the steam velocity in drum internals would be more at lower pressures. This will hamper the separation of water droplets from steam which results in carryover.
