Energy > Waste Heat Recovery Boilers (WHRB)

calderas-de-recuperacion-vaporHeat Recovery Steam Generator (HRSG)

These facilities make use of the waste heat of the exhaust gases at the outlet of Furnaces, Gas Turbines and Alternative Engines to produce steam or superheated steam, thermal oil or gas.

Our Waste Heat Recovery Boilers are designed for each unique application according to the customer’s requirements, such as: production, lay out, use of quality flue gas (dust, corrosive, etc) and the possibility of installation of erection in hazardous areas.

We are specialized in water-tube boilers (WHRB, HRSG) with or without afterburner:

  • Natural Circulation Boiler (with vertical tubes).
  • Forced Circulation Boiler (with horizontal tubes).
  • Boiler with Cleaning System for Dusty Flue Gas.

And we are specialized in HTF Recovery Boilers for Low and Medium Pressure Closed-Circuit.

Our boilers have self-cleaning systems built in for dirty gases, such as washing ramps or sootblowers (steam or compressed air) that can be used without having to stop the boiler.

We create optimized design for each turbine, engine, incinerator or furnace, adapting the design to the steam requirements of the customer, being able to overheat saturated steam and generate it simultaneously.

We provide a turn-key service including: Deaerator, chemical dosing system and all auxiliary systems needed by the boiler.

The main parts of a Waste Heat Recovery Boiler designed by AITESA are:

  • Economizer
  • Condensing economizers
  • Superheater
  • Vaporizer
  • Deaerator
  • Steam drum
