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)
