What is a steam boiler?

A steam boiler converts water into high-quality steam for industrial processes such as production, heating or cleaning. Steam is generated at controlled pressure and temperature, tailored to your process.

The right boiler guarantees continuity and prevents production downtime when faults occur. Cal Trading supplies and maintains industrial steam boilers. We handle advice, delivery, installation, maintenance and inspection support.

How does a steam boiler work?

Our steam boilers use the efficient three-pass principle. That delivers maximum heat transfer and lower emissions. For processes that use waste heat, we can add a fourth pass: waste heat boilers, ideal for energy recovery.

The three-pass principle

  • First pass: the burner heats the furnace and flue gases flow to the water-cooled reversal chamber
  • Second pass: gases flow through fire tubes back to the boiler
  • Third pass: gases leave the boiler through the stack, making optimal use of heat transfer

Low-stress design for long service life, up to 31,500 kg of steam per hour. Larger custom solutions available on request.
