Revolution adaptive – fully automated combustion control

The new Revolution adaptive control system detects the fuel quality used. It does this based on the fuel's water content, the heat capacity generated, the combustion temperature, and the current grate occupancy. The Revolution adaptive control system ensures that the residual oxygen content in the flue gas remains low even when the fuel quality varies, and that the target output is always achieved. Flue gas recirculation and air distribution are automatically adjusted and the fire bed is kept constant. This has a positive effect on efficiency, fuel consumption, emissions, and wear.

Application
Fully automated combustion control
Operating medium
PersonalTouch visio control
Operating range
from 700 kW
Fuel water content
Changing fuel qualities from M10 - M55

Pro­duct de­tails

Fuel change evaluations at Eschlikon district heating results – UTSR-1600.42 moving grate biomass boiler

Values reflect fuel change from dry waste wood M 10 to moist forest residue wood M 35
The Revolution adaptive control system compensates for the change in fuel quality during operation without manual intervention.

  • The desired target output is always achieved and the output is automatically adjusted.
  • Fluctuations in fuel moisture content due to fuel change from waste wood M 10 to forest residue approx. M 35
  • Residual oxygen is regulated to 6 % and maintained

 Advantages at a glance

Less effort for operators

  • Automatic adjustment of the nominal output independent of fuel quality
  • No manual intervention to adjust grate movement, air distribution and flue gas recirculation

Optimized combustion process

  • Constantly low residual oxygen values result in approx. 2.5 % efficiency and reduced fuel consumption
  • Reduced flue gas volume at the chimney
  • Better part load behaviour due to higher combustion temperature
  • Optimum combustion conditions and undisturbed fuel bed resulting in low emissions

Smooth / low-wear system operation

  • Optimized flue gas recirculation
  • Combustion air supply perfectly adapted to fuel quality
  • Ideal grate fuel load and grate feed

Retrofitting with Revolution adaptive

The Revolution adaptive combustion control is available for the UTSR hot water boilers with an output of 700 kW or more. It is used in combination with the system control of the latest version “PersonalTouch visio”.

 Required equipment

  • “Personal Touch Revolution adaptive” control upgrade
  • Measurement system for determining the current fuel water content
  • Detection system for grate fuel load (firebed height and length) by means of light barriers
  • Heat meter for power measurement
  • Firebox camera
  • Remote access via the Schmid portal
