What is the first thing a boiler operator must do when entering
the boiler room? .......Answer.........The first thing a boiler operator
must do when entering the boiler room is check the water level
of all boilers on line. The boiler operator should then check
steam pressures, condition of the flame, auxiliaries, and other
boiler room equipment as required.
What is the purpose of a feedwater pump? .......Answer.........The
purpose of a feedwater pump is to pump feedwater to the
boiler. The feedwater pump produces the pressure required to
overcome boiler water pressure and system resistance to
maintain the normal operating water level (NOWL).

How do each of the three types of pressure controls function to
control the operation of a burner? .......Answer.........An operating
control is a pressure control that senses steam pressure and
automatically signals the burner to initiate the start-up sequence
when steam pressure is needed and initiate the burner shutdown
sequence when steam demand is met. A high limit control is a
pressure control that senses steam pressure and automatically
shuts down the burner if the operating control fails. A modulating
control is a pressure control that works with the operating control
to vary the burner firing rate within a given range.
What is the purpose of a safety valve? .......Answer.........The
purpose of a safety valve is to prevent the boiler from
exceeding its maximum allowable working pressure (MAWP).
The safety valve is the most important valve on a boiler
, age 3 of 29
The number of blowdowns required is determined by ?
.......Answer.........boiler water analysis
A vacuum pump is a boiler accessory used to draw condensate
back from the system by producing negative pressure on the
condensate return lines. .......Answer.........vacuum
Oxygen in the boiler water causes? .......Answer.........pitting
A therm is equivalent to ? .......Answer.........100,000 BTU
A _______ draft fan is located before the furnace.
.......Answer.........forced
Impurities that increase the surface tension of boiler water are
removed with a _______ blowdown. .......Answer.........surface
The primary function of the water column on a low pressure
boiler is to reduce ? .......Answer.........Water turbulence
