responsible for ensuring that equipment has been inspected by a
jurisdictional inspector before it is placed into service. - ANSWERS-
Owner
Routine _________ is the key to maximizing the production and life
of pressure vessel(s). - ANSWERS-Maintenance
Seismic loads are: - ANSWERS-Loads are transient and, when they
occur, can result in the production of vibratory forces
The official ASME BPVC "U" symbol can only be applied to vessels
that have been _________. - ANSWERS-Inspected
_________ testing involves the pressurization of a vessel with a
compressible gas, such as air or nitrogen, to determine if any leaks are
present. - ANSWERS-Pneumatic
,The ____________ is responsible for performing the design
calculations and making them available to the jurisdictional inspector
and owner. - ANSWERS-Manufacturer
The primary hazard in _______ testing is the amount of energy stored
in the compressed gas during the test. - ANSWERS-Pneumatic
The ASME BPVC specifies that the size of an elliptical manhole must
not be less than __________ mm by __________ mm. - ANSWERS-
300, 400
In order for the nozzle to support the applied loads, _____________
may be required. - ANSWERS-Reinforcement
The ASME BPVC symbol, and the __________ serial number, shall
be stamped on the nameplate. - ANSWERS-Manufacturer's
__________ _______ are leak-proof containers that have an internal
or external operating pressure. - ANSWERS-Pressure vessels
The ___________ must be permanently applied to the vessel. -
ANSWERS-Nameplate
Pressure welders, following a qualified ________ procedure that has
been accepted by the jurisdiction, must do the welding. - ANSWERS-
Welding
,Combustion air for the burners is preheated to ______ in the air heater
section by combustion gases leaving the economizer section. -
ANSWERS-350°C
Most downcomers run horizontally between the steam drum and the
mud drum. - ANSWERS-False
Steam bubbles form in the hottest tubes and rise to the steam drum
where the steam is separated out of the water and steam mixture.
Circulation is maintained by water returning to the mud drum through
the cooler tubes. The hotter tubes (the risers) are the ones in the
radiant area of the furnace and the hottest areas of the generating bank
of tubes. - ANSWERS-True
What is the main advantage of the packaged boiler? - ANSWERS-
Low cost
Generally, two types of draft fans are used. A(n) _____ ____ fan
supplies air to the air preheater. The preheated air for combustion goes
to the coal pulverizers and to the burners. A(n) ______ ____ fan
exhausts the combustion gases from the air heater to the stack. -
ANSWERS-Forced draft, induced draft
One square metre of heating surface equals 10 kilowatts. The heating
surface of a boiler must be determined by computing the area of the
surface involved in square metres. Where a computation is to be made
of a curved surface, the surface with the greater radius is taken. -
ANSWERS-True
, When the boiler provides the entire steam supply to an electric
generating unit, the output of the boiler is expressed in terms of power
output of the generator (e.g. a 300 megawatt boiler). - ANSWERS-
True
What is the range for packaged watertube boiler capacities? -
ANSWERS-2300 kg to 65 000 kg per hour
What is the output of field-erected boilers? - ANSWERS-150 000
kg/h or more
The A-, D-, and O- type boilers have furnaces cooled by _________
lining the furnace walls. - ANSWERS-Watertubes
Where electric power is used as the heating source, the boiler rating is
the maximum kilowatt rating of which aspect? - ANSWERS-Heating
element
The difference in density between water and saturated steam becomes
progressively less with increased pressure and disappears altogether at
the critical pressure of _______ . - ANSWERS-22 090 kPa
The main feature of a controlled circulation boiler is a (circulating)
pump, which is used to provide circulation. - ANSWERS-True
It is standard practice to ________ an opening with the same cross-
sectional area that was removed. - ANSWERS-Reinforce
