Steam Boiler - Definition, Working Principle, Types, and

These on-off cycles, even in deaerated systems, upset thermal circulation by surging or flooding boilers with excess water, collapsing active steam bubbles. This can cause unstable water levels and fluctuating firing rates. An on-off system imposes an unstable load on a deaerator, causing it to react cyclically and operate at perhaps two to three times its design capacity for one-half to two-thirds of the time.
