Boiler Starup Dabal Firing
Boiler manufacturers usually provide boiler efficiency curves over several firing rates (e.g., 75%, 50%, 25%) based on laboratory results. These curves, however, rarely go below 10% of the firing rate (10:1 turndown ratio) and if they do, it should be important to take note of the excess air levels.

Boiler Cycling Considerations - Babcock & Wilcox
When the boiler startup sequence is initiated, the offline system is shut down and isolated. Warming lines permit natural circulation through the pump when it is shut down and the boiler is off line. Experience with offline recirculation systems has shown that thermal shock differentials can be reduced to less than 100F (56C) from previous levels of 200 to 400F (111 to 222C).
