boiler. These are:
A The height of the steam

B The amount of heat
applied to the tube. The
hotter the tube becomes,
the more steam bubbles
are formed, creating
more mass differential
and thus more circulation.
C The operating pressure

pressures increase, the
density of the steam
increases
D The cleanliness of the
tubes can also affect
circulation
E All of the above
The purpose of the C
