Economizer

Energy savings through heat recovery from flue gases. Feed water from the deaerator tank is preheated further, improving efficiency. An economizer can be applied to any boiler. Cal Trading supplies and installs economizers tailored to your installation.

Benefits of an economizer

An economizer recovers waste heat from flue gases. Your steam boiler uses less fuel, energy costs fall and installation efficiency rises.

Benefits include:

  • Lower fuel consumption
  • Lower energy costs
  • Lower CO₂ emissions
  • Higher efficiency from your steam boiler
  • Easy to integrate into existing installations
  • Supports sustainability goals

Applications of an economizer

Economizers are used in industrial steam installations where energy savings and efficient use of heat matter. They add value in new plants and existing boiler houses alike.

  • Food industry
  • Chemical industry
  • Pharmaceutical industry
  • Process industry
  • Production sites with high steam demand
  • Making existing installations more sustainable
  • New steam and boiler installations

Savings and payback for an economizer

An economizer typically raises steam plant efficiency by 2 to 5% by recovering and reusing heat from flue gases. Fuel consumption falls and energy costs can drop significantly.

Indicative figures:

  • 2 to 5% higher efficiency
  • 3 to 6% lower fuel consumption
  • Pharmaceutical industry

Frequently asked questions

Even more efficiency

A flue gas condenser recovers even more heat from flue gases. It can cool further than an economizer, so latent heat can be used too.

  • Flue gas condenser including controls and flue gas dampers
  • Heat recovery from blowdown and flash steam
  • Steam trap survey: prevent energy loss from leaking steam

Blowdown heat recovery

Flash steam from blowdown can be recovered and used in your deaerator tank. The remaining condensate flow can preheat your make-up water. That improves installation efficiency.
