Description

A solid fuel fire tube boiler is a type of boiler that uses solid fuels—such as coal, wood, or biomass—to generate steam or hot water. Here’s a brief overview of how it works and its key features:

 

Key Components

  • Fire Tubes: These are tubes where the hot gases from the combustion of solid fuel pass through. The surrounding water absorbs the heat from these gases, leading to steam or hot water production.
  • Furnace: This is where the solid fuel is burned. It usually includes a grate for fuel placement and air for combustion.
  • Water Chamber: Surrounding the fire tubes, this chamber holds the water that will be heated into steam.
  • Smoke Stack: It vents the exhaust gases produced during combustion.

Specifications

Working Principle

  • Fuel Combustion: Solid fuel is fed into the furnace, where it is ignited. Air is supplied to promote combustion.
  • Heat Transfer: The hot gases produced travel through the fire tubes, transferring heat to the surrounding water.
  • Steam Production: As the water absorbs heat, it converts to steam, which can be used for heating or power generation.
  • Exhaust Gases: The remaining gases exit through the smoke stack, often with some heat recovery systems in place to improve efficiency.

Advantages

  • Fuel Flexibility: Can utilize a variety of solid fuels, including renewable options like wood pellets.
  • Cost-Effective: Solid fuels are often cheaper than gas or oil.
  • Robustness: Generally durable and capable of handling harsh operating conditions.

Applications

  • Industrial processes
  • District heating
