The main types of industrial boilers are:

  • Fire Tube Boilers: Hot gases pass through tubes surrounded by water. Common in smaller applications.
  • Water Tube Boilers: Water flows through tubes heated by the fire, used for high-pressure applications.
  • Fluidized Bed Boilers: Used for burning various fuels efficiently and are typically found in power generation plants.
  • Waste Heat Boilers: Designed to recover energy from exhaust gases.
