Pyrot

Rotation firing system 150 to 540 kW

The patented rotation firing system of the Pyrot wood-fired boiler represents the state of the art in wood-fired heating systems. An infeed screw conti­nuously drives the wood fuel onto a moving grate, where the fuel is gasified (under a lambda-regulated primary air supply). The conti­nuous gasifi­cation takes place under air starvation. A rotary blower mixes the rising combustion gases with secondary air that has been atomised and induced to rotate. This ensures good mixing with the combustion gases.

Clean and efficient combustion


Fuels:
Wood pellets
Wood chips
Wood shavings

The combi­nation of combustion technology with digitally modulated output regulation enables effici­encies of up to 94%.

Clean and efficient combustion

The proven combustion technology of the Pyrot can be used as a wood chip boiler, pellet boiler or wood shavings and mixed wood boiler. Depending on the fuel, it achieves similar emissions values to a modern gas-fired system and keeps the emission of CO, NOx and dust particles to a minimum. The combi­nation of combustion technology with digitally modulated output regulation enables effici­encies of up to 94%.

Mobile container-based heating centre

Pyrot wood-fired boilers are available as a container-based turnkey solution for appli­ca­tions where no boiler enclo­sures are available or where site construction costs must be kept to a minimum. This turnkey solution includes the wood-fired boiler pre-installed in a special container as well as the supple­mental equipment. Individual container solutions can be specially adapted to specific needs.

Boiler control

The digital modulating output regulation ensures optimal combustion thanks to precise regulation of the ratios of combustion air, recir­cu­lated flue gas and fuel. The control system monitors:

  • Supply and return tempe­rature of the wood-fired boiler
  • Fire bed condition
  • Light barriers of the infeed system
  • Flue gas tempe­rature
  • Oxygen content of the flue gas (lambda probe)
