Accepted Answer

The answer of Steam is used in the following applications:...

Question 2

List six types of tubes found in a water-tube boiler.

Accepted Answer

The answer of List six types of tubes found in...

Question 3

Used to evenly distribute air and fuel vapors over an ignition source and into a boiler firebox.
A) flame distributor
B) igniter
C) burner
D) flare tip

Accepted Answer

A burner is used to evenly distribute air and fuel vapors over an ignition source and into a boiler firebox.

Question 4

A section of the boiler utilized to preheat feed water before it enters the main boiler system.
A) convection section
B) economizer section
C) radiant tube section
D) shockbank

Accepted Answer

The economizer section is used to preheat feed water before it enters the main boiler system.

Question 5

As steam flows from the boiler to the plant it begins to cool. When steam cools it forms _______________ .

Accepted Answer

The answer of As steam flows from the boiler to...

Question 6

Slugs of water can damage equipment and lead to a condition known as:
A) thermal expansion
B) water hammer
C) thermal shock
D) warping

Accepted Answer

Water hammer is a condition caused by a sudden change in water flow, creating pressure surges or slugs that can damage equipment.

Question 7

The inlet line to the lower (drum)header.
A) downcomer
B) riser
C) steam generating
D) desuperheated

Accepted Answer

The downcomer is the inlet line that carries water from the steam drum to the lower drum or header in a boiler system.

Question 8

The principle reason water circulation occurs in a water tube boiler is because of:
A) natural buoyancy forces
B) equipment design
C) tapered design of steam generating tubes
D) length of riser tube

Accepted Answer

Natural buoyancy forces cause water circulation in a water tube boiler as hot water rises and cooler water descends, creating a natural convection current.

Question 9

The shortest discharge line from the lower (drum) header.
A) riser
B) downcomer
C) steam generating
D) superheated

Accepted Answer

The riser is the shortest discharge line from the lower drum header, as it carries water and steam upward to the steam drum.

Question 10

Some processes can not take superheated steam so a process known as desuperheating is applied to remove this additional heat. This process routes the superheated steam through the liquid level in the upper drum.
A) boiler load
B) superheated steam
C) desuperheated steam
D) cut in the line

Accepted Answer

Desuperheated steam is the result of the desuperheating process, where superheated steam is cooled to remove excess heat, making it suitable for processes that cannot handle superheated steam.

Question 11

Identify the following components:

Accepted Answer

The answer of Identify the following components:
 ...

Question 12

A steam trap that operates with an upside-down bucket inside a casing. It is effective on condensate and non-condensing vapors.
A) inverted bucket trap
B) floating bucket trap
C) bellows bucket trap
D) thermostatic steam trap

Accepted Answer

An inverted bucket trap uses an upside-down bucket inside a casing to trap steam and release condensate and non-condensing vapors effectively.

Question 13

The lower drum (header.)
A) steam generating drum
B) mud drum
C) lower drum
D) generating tube

Accepted Answer

The answer of The lower drum (header.)
A) steam generating drum
B)...

Question 14

Steam that is removed from the water and heated up to a higher temperature.
A) boiler load
B) superheated steam
C) desuperheated steam
D) cut in the line

Accepted Answer

Superheated steam is steam that has been heated to a temperature higher than its boiling point at a given pressure.

Question 15

A device used to separate liquids from gases and return them to a condensate header.
A) strainer
B) steam bucket
C) steam trap
D) check valve

Accepted Answer

A steam trap is used to separate condensate (liquid) from steam (gas) and return it to a condensate header.

Question 16

A steam trap that operates with a float that opens a valve as the condensate level rises.
A) inverted bucket trap
B) float trap
C) floating bellows trap
D) thermostatic float steam trap

Accepted Answer

A float trap operates with a float that opens a valve as the condensate level rises.

Question 17

Please draw and label a fire tube boiler.

Accepted Answer

The answer of Please draw and label a fire tube...

Question 18

There is a direct correlation between steam temperature and:
A) analytical variables
B) flow rates
C) level in steam generating drum
D) pressure

Accepted Answer

Steam temperature is directly correlated with pressure, as an increase in pressure typically results in an increase in steam temperature.

Question 19

Super high pressure steam is between:
A) 50-60 psig
B) 180-200 psig
C) 1000-1200 psig
D) 1800-2200 psig

Accepted Answer

Super high pressure steam is between 1000-1200 psig.

Question 20

The primary purpose of a condensate recovery system is: Select all that apply!
A) Save money
B) Remove oxygen
C) Return water to boiler.
D) Remove slugs of water from steam.

Accepted Answer

The answer of The primary purpose of a condensate recovery...
