Control of a peak load boiler of a biomass district heating plant at EnergieComfort Tannheim GmbH

Project's goals:

Minimization of the fuel oil consumption by performing a system integration of a B&R APROL process control system into the existing control set. We developed a solution fully satisfying the customer using X20 controllers and a Profibus-DP connection.

Plant data:

  • Performance of the bi9omass boiler: 2,5 MW thermal
  • Performance of the fuel oil boiler: 3 MW thermal


  • Savings of fuel oil of > 15% on all days with comparable external temperature.
  • Very short project duration of < 14 days on site.
  • ROI < 6 months
