I have water tube boiler and I need to ask about the max. number of tubes in bank tubes (boiler side) can be plugged (due to leakage which difficult to be replaced) that do not cause fail or limit in steam production.

I would look at the impact of the loss of heat transfer area and impact of velocity through the remaining tubes.
crshears said:Is not velocity in tubes generally defined by the head between upper and lower drums, the ID of the tubes, and the triad of quantity of heat transferred / amount of steam generated / percentage phase mixture at the upper / exit ends of the tubes? And since all of the foregoing are more or less fixed for a given firing rate, will not the velocity within the tubes remain relatively unchanged?
