BOILER COMPONENTS

Key Boiler Components

Boilers consist of several critical parts for combustion, heat transfer, and safety: 

  • Burner: Initiates the fuel/air mix combustion.

  • Combustion Chamber: Area where fuel is burned.

  • Heat Exchanger: Transfers heat from combustion gases to water.

  • Circulator Pump: Pushes hot water through supply lines.

  • Expansion Tank: Manages pressure changes in the system.

  • Controls/Aquastats: Manage temperature and ignition signals.

  • Safety Valves/Backflow Valves: Ensure single-direction fluid flow.

  • Economizer: Heat exchanger in the exhaust stream.

  • Superheater: Used in steam boilers to increase steam temperature.

  • Deaerator/Condenser: Removes gases from liquid.

  • Refractory: Insulating material in the combustion chamber.
