(False questions omitted)
33,478 BTUs equal - ANSWER-One boiler horsepower
.A boiler pressure gauge gives readings in - ANSWER-Gauge pressure
.A compound gage is calibrated to read - ANSWER-Vacuum and pressure
.a convection type superheater - ANSWER-absorbs its heat from the hot gases of
combustion
.A device used to steady the discharge of a pump. - ANSWER-Air chamber
.A device, which utilizes centrifugal force to remove moisture from steam. - ANSWER-
Dry pipe
.a firetube contains - ANSWER-the products of combustion
.A good over the fire draft in a natural draft furnace should be approximately -
ANSWER-.05 inches of water negative pressure
.A hydrostatic test is a test for - ANSWER-the tightness of boiler drums and tubes
.a pigtail is used on a steam gauge connection to - ANSWER-prevent damage to the
gauge
.A specially constructed valve used on many receivers in a ammonia compression
system - ANSWER-King Valve
.A super heater - ANSWER-raises the temperature of steam
.A temperature controlled device used in heating systems - ANSWER-thermostatic trap
.A two-stage air compressor contains - ANSWER-2 Cylinders
.A valve generally used as a pressure shut-off valve is a - ANSWER-Gate valve
, .A vapor can best be defined as a - ANSWER-physical state between a liquid and a gas
.Air contains what percent of oxygen - ANSWER-20%
.All Boilers should be viewed as - ANSWER-Dangerous regardless of size and pressure
.All residential air conditioners use - ANSWER-Freon
.All vacuum return heating systems require - ANSWER-traps
.An accumulation test is used to determine - ANSWER-the relieving capacity of a safety
valve
.An ammeter is always connected to an electric circuit in - ANSWER-Series with a shunt
.An economizer uses waste heat to raise the temperature of - ANSWER-Feed water
.An example of heat transfer by radiation is - ANSWER-Heat from the sun
.at sea level, water boils at - ANSWER-212 Degrees F
.Boiler water can be conditioned by - ANSWER-heating addition of chemicals and by
blow down
.Coils located in the boiler breeching utilizing waste heat - ANSWER-Air preheater
.Convert -40Degrees centigrade to fahrenheit - ANSWER-C = (F-32) / 1.8
-40 = (F - 32) / 1.8
-72 = F - 32
-40 = F
.Convert 86 Fahrenheit to centigrade - ANSWER-C = (F-32) / 1.8
C = (86-32)/1.8
C = 30 Degrees C
.Cools the refrigerant and changes it from a gas to a liquid in a ammonia compression
system - ANSWER-Condenser
.Eliminates non-condensable gases from the ammonia compression system -
ANSWER-Purge Valve
.Fan located ahead of the fuel burner - ANSWER-Forced draft fan
.Fan located in the boiler breeching - ANSWER-Induced Draft fan
