Exam 9: Steam Generation- Boilers

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

A group of gas filled tubes in a natural gas burner

Used to evenly distribute air and fuel vapors over an ignition source and into a boiler firebox.

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

The primary purpose of a condensate recovery system is: Select all that apply!

There is a direct correlation between steam temperature and:

Boilers produce a variety of steam temperatures and pressures.

Identify the following components:

The principle reason water circulation occurs in a water tube boiler is because of:

The water make-up system takes its level measurement from the:

The convection section in a fired heater most closely resembles the ____________ section in a boiler.

A steam trap that operates with an upside-down bucket inside a casing. It is effective on condensate and non-condensing vapors.

A device used to separate liquids from gases and return them to a condensate header.

The lower drum (header.)

The burners in a water tube boiler are surrounded by which tubes:

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 type of boiler that passes hot gases through tubes to heat up and vaporize water.

Steam is used in the following applications:

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

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