A) inverted bucket trap
B) float trap
C) bellows trap
D) thermostatic steam trap

Accepted Answer

A bellows trap operates by opening or closing a bellows as the temperature changes. This movement opens and closes a valve.

Question 4

A type of steam trap that is controlled by temperature changes.
A) inverted bucket trap
B) float trap
C) bellows trap
D) thermostatic steam trap

Accepted Answer

A thermostatic steam trap operates based on temperature changes, opening and closing as the temperature of the steam and condensate changes.

Question 5

A boiler is most closely defined as a:
A) device used to convert steam energy into mechanical energy
B) device used by industry to boil water and produce steam
C) fire tube filled container submerged in water
D) furnace with water filled drums and tubes passing through it

Accepted Answer

A boiler is primarily used to boil water and produce steam, which can then be used for various industrial applications.

Question 6

Boiler load is most closely defined as a:
A) plants demand for steam
B) boilers steam capacity
C) boilers total energy demand
D) water load in boiler tubes

Accepted Answer

Boiler load refers to the demand for steam from the plant, which the boiler must meet.

Question 7

Boilers produce a variety of steam temperatures and pressures.

Accepted Answer

Boilers are designed to generate steam at different temperatures and pressures depending on their application and design specifications.

Question 8

Write a paragraph describing step by step what happens as a boiler is started up.

Accepted Answer

The answer of Write a paragraph describing step by step...

Question 9

The steam generating drum is typically operated:
A) 1/4 full
B) 1/2 full
C) 3/4 full
D) Liquid full

Accepted Answer

The steam generating drum is typically operated at about half full to allow for steam space above the water level and to accommodate fluctuations in water level during operation.

Question 10

The downcomer is connected to:
A) mud drum and steam generating tubes
B) steam generating drum and mud drum
C) deaerator and economizer tubes
D) superheated and desuperheated tubes

Accepted Answer

The downcomer is a pipe that connects the steam generating drum (also known as the steam drum) to the mud drum in a boiler system, allowing water to circulate between these components.

Question 11

The water make-up system takes its level measurement from the:
A) deaerator and steam generating drum
B) economizer and deaerator
C) mud drum
D) superheated tubes

Accepted Answer

The water make-up system typically takes its level measurement from the deaerator and steam generating drum to ensure proper water levels are maintained for efficient steam generation and system operation.

Question 12

Fans are used in a water tube boiler system to:
A) cool the burners
B) control oxygen flow rate
C) distribute heat
D) blow hot gases out the stack

Accepted Answer

Fans in a water tube boiler system are primarily used to control the oxygen flow rate, which is essential for efficient combustion and maintaining the correct air-to-fuel ratio.

Question 13

The deaerator has the following flows in and out except:
A) safety valve (out)
B) pump (out)
C) chemical additives (in)
D) oxygen vent (out)
E) water make-up (in)
F) steam generating drum (out)

Accepted Answer

The steam generating drum is not a flow out of the deaerator; it is typically a component in a boiler system where steam is generated, not directly related to the deaerator's function of removing dissolved gases from feedwater.

Question 14

The coolest tube in the boiler system is the:
A) economizer tube
B) water make-up
C) steam generating
D) superheated

Accepted Answer

The answer of The coolest tube in the boiler system...

Question 15

Identify the following components:

Accepted Answer

The answer of Identify the following components:
 ...

Question 16

The burners in a water tube boiler are surrounded by which tubes:
A) riser and downcomer
B) superheated and desuperheated
C) steam generating tubes
D) economizer tubes

Accepted Answer

The burners in a water tube boiler are surrounded by steam generating tubes, which are responsible for transferring heat from the burners to the water in the boiler.

Question 17

Flow moves in the opposite direction in these tubes.
A) downcomer and steam generating
B) riser and downcomer
C) riser and steam generating
D) a & b

Accepted Answer

In a natural circulation boiler, flow moves in the opposite direction in the riser and downcomer tubes.

Question 18

The steam generating tubes are connected to the:
A) riser and downcomer
B) economizer and water make-up
C) superheated and desuperheated
D) mud drum and steam generating drum

Accepted Answer

The answer of The steam generating tubes are connected to...

Question 19

A) direct fired furnace
B) fire and water tube
C) indirect fired furnace
D) all of the above
