The purpose of a power boiler is to create steam by applying heat energy to water. The necessary heat energy is produced by combustion. Fuel and oxygen are required for combustion to occur. To ensure complete combustion of the fuel in the boiler furnace, enough air must be thoroughly mixed with the fuel. Each power boiler fuel requires a different amount of air for complete combustion and the combustion controls must be designed to provide it. This module describes the role of combustion in power boilers as well as major components and flows of power boiler air systems.

Learning Objectives

  • Identify and describe the safety hazards and guidelines associated with power boiler air and combustion
  • Define "combustion"
  • Explain the role of combustion in power boilers
  • Describe the two basic air systems for power boilers
  • Identify and describe major components of power boiler air systems
  • Identify and describe the primary process flows
  • Describe factors that affect the combustion process
  • Differentiate between the firing techniques needed for good combustion depending on the fuel

Key Questions

The following key questions are answered in this module:

What is combustion?
Combustion is the rapid chemical combination of oxygen with the combustible elements of a fuel, resulting in production of heat.

What is the role of combustion in power boilers?
Combustion creates steam by applying heat energy to water.

What are the two basic air systems for power boilers?
Pressurized furance and balanced draft.

What are the major components of a power boiler air system?
Forced draft fan, air heater, windbox, primary air fan, overfire air fan, and induced air fan.

Sample Video Transcript

Below is a transcript of the video sample provided for this module:

The purpose of a power boiler is to create steam by applying heat energy to water. The necessary heat energy is produced by combustion. Fuel and oxygen are required for combustion to occur. Air, which is 21% oxygen, provides the oxygen, while the major fuels used in the power boiler are natural gas, fuel oil, coal, and biomass. Design characteristics of power boilers differ depending on the fuel burned. These characteristics include shape of the furnace, air system design, tube spacing, super heater design, and the type of air pollution equipment installed. To ensure complete combustion of the fuel in the boiler furnace, enough air must be thoroughly mixed with the fuel. Each power boiler fuel requires a different amount of air for complete combustion, and the combustion controls must be designed to provide it.
