The boiler house is a building or part of a building in which one or several steam boilers are installed. The auxiliary systems required for operation of the steam boiler are also normally installed in the same room.

These are specific systems for:

  • Water treatment
  • Water disposal
  • Treatment, distribution and storage of steam and condensate
  • Monitoring of the water quality
  • Automation and control technology
  • Heat recovery

Special regulations apply in this area.

The following diagram shows an example of the water-steam mass balance. The mass flow rates must be set up for every boiler house individually depending on the system components and operating conditions and are essential to any planning.

Freshwater for softening

     

Losses due to bottom/surface blowdown

Losses during softening due to the regeneration

 

Steam to the consumers

Make-up water for deaerating

 

Condensate

Cooling water for the bottom blowdown vessel

 

Losses at the consumers (e.g. due to direct use)

Feed water to the steam boiler
