A boiler operator have to have the following quantity of months on-the-job training before he can
take the operator's examination. - ANS-6 months minimum
A boiler operator operating a boiler that he is aware of is risky might also, or may additionally
NOT have his license revoked. - ANS-False
A boiler operator running a boiler without a license will be guilty of a misdemeanor and upon
conviction thereof will be punished via a pleasant of no longer less than $25.00 and no longer
more than
$one hundred.00, and in addition can be imprisoned for not greater than 2 years, or each. True
or fake? - ANS-True

A high-pressure steam boiler operates at a strain above 15 psi. - ANS-True
A low-water cut-off device does no longer have an effect on the gasoline to the boiler while the
water level drops. - ANS-False
A safety tool used to reduce gasoline to the boiler whilst the water level falls under a secure
level. - ANS-Low-water reduce-off
A steam lure is a device used to release condensation and preserve steam in a radiator or
return line. True or fake? - ANS-True
A steam valve should be opened slowly. True or fake? - ANS-True
ABSOLUTE PRESSURE - ANS-The sum of gauge stress and atmospheric strain.
ACCESSORY - ANS-Piece of system now not without delay attached to the boiler however
necessary for its operation.
ACCUMULATION TEST - ANS-Test used to establish the relieving capacity of boiler protection
valves.
,AIR COCK - ANS-See BOILER VENT.
AIR EJECTOR - ANS-Steam-pushed device that eliminates air and other noncondensable
gases from the condenser, consequently keeping a higher vacuum.
AIR FLOW SWITCH - ANS-Proves that number one air is furnished to the burner.
AIR HEATER - ANS-Supplies heated air for combustion. Located within the breeching among
the boiler and chimney.
AIR TO FUEL RATIO - ANS-Amount of air and gasoline furnished to the burner over high and
occasional fireplace.
ALKALINITY - ANS-Determined via boiler water evaluation. Boiler water with a PH over 7 is
considered alkaline.
AMBIENT TEMPERATURE - ANS-Temperature of the encompassing air.
ANTHRACITE COAL - ANS-Hard coal that has a high constant carbon content material.
As boiler steam strain increases, there is a corresponding boom within the: - ANS-Temperature
ASH HOPPER - ANS-Large receptacle used to shop ashes till they may be disposed of.
ASME CODE - ANS-Code written via the American Society of Mechanical Engineers that
controls the construction, repairs and operation of steam boilers and their associated system.
ATMOSPHERIC PRESSURE - ANS-Pressure at sea degree (14.7 psi).
ATOMIZE - ANS-To cut up liquid into a pleasant mist.
AUTOMATIC NONRETURN VALVE - ANS-Valve positioned at the steam line closest to the shell
of the boiler that cuts the boiler in on the line and rancid-line automatically. This valve also
protects the gadget in the event of a large steam leak on any boiler.
AUXILIARIES - ANS-Equipment vital for the operation of a boiler.
BAFFLES - ANS-Direct the direction of the gases of combustion in order that the most
warmness could be absorbed with the aid of the water before the gases of combustion input the
breeching and chimney.
, BALANCED DRAFT - ANS-When the intake damper is automatically managed by using the
strain within the furnace. Furnace stress is maintained slightly underneath atmospheric
pressure.
BENT - ANS-TUBE BOILER- A water tube boiler with multiple drum wherein the tubes connect
the drums.
BITUMINOUS COAL - ANS-Soft coal that has a excessive volatile content material.
BLOWDOWN TANK - ANS-Coded tank vented to the ecosystem that protects sewer strains
from boiler stress and high temperature when blowing down.
BLOWDOWN VALVES - ANS-Found at the boiler blowdown line at the lowest a part of the water
facet of the boiler.
BLOWOFF VALVE - ANS-To offer a method of draining, flushing and blowing off the boiler on
the low factor to eliminate the concentrated solids, sediment, seals and sludge of maintaining
the boiler easy.
BOILER CAPACITY - ANS-Pounds of steam per hour that a steam boiler is capable of
producing. BOILER EXPLOSION- Caused by means of a unexpected drop in stress (failure on
the steam aspect) without a corresponding drop in temperature.
BOILER HORSEPOWER - ANS-The evaporation of 34.Five pounds of water per hour from and
at a feedwater temperature of 212°F.
BOILER LAY - ANS-UP- Removing a boiler from carrier for an extended time frame. A boiler can
be laid up moist or dry.
BOILER ROOM LOG - ANS-A records sheet used to report pressures, temperatures and
different working situations of a boiler on a continuous basis.
BOILER SHUTDOWN - ANS-A series of operations completed while taking a boiler off-line.
BOILER START - ANS-UP- A collection of operations completed whilst getting ready a steam
boiler for service.
BOILER TUBES - ANS-Used to carry water or warmth and gases of combustion. May be
instantly or bent tubes.
BOILER VENT - ANS-Line coming off the highest a part of steam facet of the boiler this is used
to vent air from the boiler whilst filling with water and whilst warming the boiler. Also used to
prevent a vacuum from forming while taking the boiler off-line. Also referred to as air cock.
