This is the deterioration of boiler metal caused by oxygen and carbon dioxide.  This can be pitting and channelling of the metal.  

What is corrosion?

100

The purpose of this equipment is to deliver fuel oil to the boiler in a fine spray so that it mixes with oxygen for efficient combustion.

What is a fuel oil burner?

100

This type of natural gas burner uses high velocity air to create a venturi effect, pulling the natural gas with the air and mixing it before the combustion chamber. 

What is a low-pressure gas burner?

100

This fuel is garbage from residential and commercial uses.  Creating energy using garbage is a secondary benefit, the true benefit is reducing the landfill quantity by 90%.

What is waste to energy, or what is municipal solid waste? 

100

In this type of coal stoker, bituminous coal is fed into the boiler in both suspension and on the grate.  It is also known as an overfeed stoker or a sprinkler stoker.

What is a spreader stoker?

200

This is when large amounts of water is passed to the steam lines.  This is a dangerous condition that can cause water hammer.

What is priming?

200

This type of fuel oil burner works to atomize the fuel oil using a spinning cup and high-velocity air.

What is a rotary cup burner?

200

This type of burner is highly beneficial because you can choose to burn the fuel that is least expensive for the day and also have flexibility in your operation if one type of fuel supply requires maintenance.

What is a combination natural gas and fuel oil burner?

200

This is a term for fuel that was once living and is considered a renewable resource.  Examples include:

-wood chips

- rice hulls

- corn stalks

What is biomass?

200

This is one way coal is categorized.  The coal's hardness determines this category.

What is the rank of coal?

300

This is when there is a rapid fluctuation of water level in the boiler or steam drum.  This condition occurs when steam bubbles are trapped below a film of impurities in the boiler water.  

What is foaming?

300

The purpose of this equipment is to remove particles in order to protect the fuel oil pump as well as to remove impurities after the pump - to make sure the fuel gets to the burner with out clogging it up.

What is a duplex strainer?

300

- relatively cheap

- lower polluting than coal or fuel oil

- readily available in many areas

What are the benefits of natural gas?

300

When a garbage mound is capped off, you can drill holes down into the "hill".  Once you insert the perforated piping, the methane gas is captured so that you can burn it in a boiler.

What is landfill gas?

300

In this equipment, coal is ground into a fine powder so that the air and fuel can mix better.  The coal powder is burned in suspension.

What is a pulverizer?

400

This is a measure of the concentration of impurities that are in solution with the boiler water.  The condition is measured using a conductivity meter.  As this condition worsens, the conductivity of the boiler water increases.  

What are total dissolved solids?

400

This equipment increases the temperature of the fuel oil and lowers its viscosity for easy pumpability.

What is a fuel oil heater?

400

- Mostly methane, some ethylene, some hydrogen, moisture and impurities

What is the chemical makeup of natural gas?

400

This is when there is a biological breakdown of matter in the absence of oxygen.  Organic waste such as cow manure, plant materials, and sewage can all be broken down to create methane for use in a boiler or engine.  

What is digester gas?

400

In this type of coal stoker, coal is fed into the boiler on a traveling grate.  A gate controls the thickness of the coal bed on the grate.  The amount of coal burned depends upon the thickness of the fuel bed, the rate of grate travel and the amount of air supplied.

What is a chain grate stoker?

500

This is a boiler chemical used as an internal treatment.  It is commonly referred to as an "oxygen scavenger" because it removes trace amounts of oxygen in the boiler water.

What is sodium sulfite?

500

This equipment is used to clean the soot off the economizer or air heater tubes.

What is a rotary soot blower?
500

- extremely explosive

- health risks associated with shale fracking

- fossil fuel, limited resource

- fossil fuel, creates carbon dioxide 

What are the risks of using natural gas?

500

This equipment is set up on a track so that it can move in and out of the extremely hot furnace to clean the soot off the boiler tubes.  This device cleans the superheater and water wall tubes.  

What is a retractable soot blower?

500

In this type of boiler, coal is burned in a limestone/sand mixture in order to absorb the sulfur dioxide.  Low firing temperatures minimize thermal NOx, making this type of boiler a better choice environmentally.

What is a fluidized bed boiler?
