becomes, the more steam bubbles are formed, creating more mass
differential and thus more circulation.
C The operating pressure of the boiler. As boiler pressures increase, the
density of the steam increases
D The cleanliness of the tubes can also affect circulation
E All of the above - answer--E
The purpose of the downcomer is to supply:
