An attended boiler is a _______________________.
a) A boiler with two fuel pumps that allow steam to smoothly transfer Sodium Dioxide.
b) A boiler with no steam trap or shut off valve which requires additional safety, maintenance and monitoring.
c) This is a boiler that is only operated when a qualified operator is present to water over and control the various boiler functions. This is normally the case for very high pressure boiler operations.
d) A boiler with two shut off valves that allow for the operator to check the boiler less often
This is a boiler that is only operated when a qualified operator is present to water over and control the various boiler functions. This is normally the case for very high pressure boiler operations.
A high pressure steam boiler is a _______________.
a) This boiler operates at pressures above 103 kPa (15 psig). These are also called Power Boilers.
b) This boiler operates at pressures below 103 kPa (15 psig). These boilers are not called Power Boilers but called Steam Pressure Inflated Boilers.
c) A high pressure steam boiler tends to overheat and requires continuous monitoring
d) A high pressure steam boiler can kill an operator when the temperature increases beyond 103 kPa (15 psig).
This boiler operates at pressures above 103 kPa (15 psig). These are also called Power Boilers.
A Hot Water Boiler is defined as ________________.
a) Hot water boilers require the operator to check the water temperature every 15 minutes.
b) These boilers have pressure valves that rotate water throughout the boiler increasing the heat temperature
c) A closed vessel completely filled with water to which heat is applied to raise the temperature of the water. Steam is “not” produced in this boiler.
d) This boiler operates at pressures above 103 kPa (15 psig). These are also called Power Boilers.
A closed vessel completely filled with water to which heat is applied to raise the temperature of the water. Steam is “not” produced in this boiler.
Low temperature hot water heating boilers __________.
a) Can operate up to 121 C (250 F) and pressures up to 1100 kPa ( 160 psi ).
b) Can operate up to 131 C (280 F) and pressures up to 2200 kPa ( 220 psi ).
c) Are often referred to as Dimmed Small Water boilers
d) Can also be classed as High temperature hot water boilers
Can operate up to 121 C (250 F) and pressures up to 1100 kPa ( 160 psi ).
Other types of hot water boilers include:
a) Hot water heater
b) Hot water tank
c) Hot water Column
d) Both A or B
Both A or B
Low pressure steam boilers ____________.
a) have a disadvantage of becoming too hot
b) produce more steam and therefore require the steam traps to be opened periodically by the operator
c) A boiler which operates at a pressure not above 103 kPa (15 psig).
d) are prone to shut offs due to trapped steam
A boiler which operates at a pressure not above 103 kPa (15 psig).
Please define a “Steam Boiler” in short answer.
THIS IS A SHORT ANSWER QUESTION.
This is a closed container partially filled with water. The water is evaporated to steam under pressure by the application of heat. The steam is then removed for specific purposes.
An unattended boiler ______________.
a) This boiler is self efficient and very expensive because no parts of this boiler require maintenance or repair. This boiler can go for decades without requiring service.
b) is a bad idea because the maintenance operator is required to periodically check all boilers
c) is prone to excessive amounts of rust and tarnish and is therefore not installed in buildings very often
d) This boiler will start up and shut down on its own automatically without the presence of a boiler operator. It is designed to run on automatic operation with fail-safe equipment and controls, but is subject to regular checks by a trained and certified boiler operator.

The ASME refers to the ____________.
a) American Steam Mechanics Engineers which is the group that set up a committee in 1911
b) American Society of Mechanical Engineers which is the group that set up a committee in 1911
c) American Steam Mechanics Engineers which is the group that set up a committee in 1931
d) American Society of Mechanical Engineers which is the group that set up a committee in 1931
American Society of Mechanical Engineers which is the group that set up a committee in 1911
The “National Board of Boiler and Pressure Vessel Inspectors” is _____________.
a) A committee designed to establish rules of safety governing the design, fabrication and inspection during construction of boilers and pressure vessels
b) Recognized legislation of standards for boilers and pressure vessels
c) Another body concerned with the promotion of safety and uniformity in the construction, installation and inspection of boilers and pressure vessels
d) A governing body that determines who operates, maintains and monitors boilers and pressure vessels
Another body concerned with the promotion of safety and uniformity in the construction, installation and inspection of boilers and pressure vessels
First organized in 1919*
In Canada, ASME codes are complemented by ________.
a) The National Board of Boiler and Pressure Vessel Inspectors
b) The Canadian Standards Association (CSA) B51, which is the Boiler, Pressure Vessel and Pressure Piping Code
c) American Society of Mechanical Engineers
d) Safety training for the operation of boilers and pressure vessels
b) The Canadian Standards Association (CSA) B51, which is the Boiler, Pressure Vessel and Pressure Piping Code
What is the CSA B52 code?
a) National Board
b) ASME
c) Mechanical Refrigeration Code
d) Canadian Standards Association
c) Mechanical Refrigeration Code
When seeking guidance about boiler and pressure vessel operation and repair the Power Engineer should recognize the ‘hierarchy’ or priority of legislations. Please put the code priority in order:
a) The appropriate CSA codes, the appropriate ASME codes, the Act and regulation of the jurisdiction (province or territory), in which the equipment is being operated or repaired
b) The Act and regulation of the jurisdiction ( province or territory), in which the equipment is being operated or repaired, the appropriate CSA codes, the appropriate ASME codes.
c) The appropriate ASME codes, The Act and regulation of the jurisdiction ( province or territory), in which the equipment is being operated or repaired, the appropriate CSA codes
The Act and regulation of the jurisdiction ( province or territory), in which the equipment is being operated or repaired, the appropriate CSA codes, the appropriate ASME codes.
What is thermodynamics?
