Boiler Fuel and Air Systems

 At the end of this lesson, you will be able to identify the basic equipment found in highpressure gas systems and fuel oil systems and describe the design and operation of fuel oil burners. In addition, you will be able to describe boiler draft and identify the different equipment used to control draft in a boiler.

• Identify the location of the furnace within the boiler and describe how fuel and air flow affect the firing rate of the boiler

• Describe the basic equipment found in high-pressure gas burner systems and explain their operation

• Describe the basic components found in a typical fuel oil system

• Describe three types of atomizing fuel oil burners and explain the operation of each type

• Define the following terms: – Draft – Forced draft – Induced draft – Balanced draft
