With its patented rotation combustion, the Pyrot wood boiler repre-
sents state of the art wood combustion. A supply screw conveyor con-
tinuously guides the wood fuel onto a moving grate on which the fuel
combustion takes place. Continuous gasification takes place under air
starvation. A rotary fan is used to mix rising combustion gases with the
secondary air displaced in a rotary motion. This ensures thorough
mixing with the combustion gases.
Clean and efficient combustion
The proven combustion technology in the Pyrot achieves similar emis-
sions values to those of a modern gas combustion system and keeps
the release of CO, NOx and dust particles to a minimum, subject to
fuel type. The combination of combustion technology and digital mod-
ulating output control enables efficiency levels of up to 92 %.
Mobile containerised heating centre
Pyrot wood boilers are available as containerised complete solutions
for uses where there are no boiler houses available or where the on-
site building costs have to be reduced to a minimum. This complete
solution incorporates the pre-assembled wood boiler inside a special
container with all ancillary devices. In addition to finished container
solutions, individual versions can be specially matched to your
needs.
Benefits at a glance
■ High efficiency levels (up to 92 %) and low emissions through regu-
lated primary and secondary air supply and low particle combustion
■ Two-pass heat exchanger and modulating output control (4:1 control
range)
■ Automatic ignition prevents having to maintain the incandescent bed
and saves fuel
■ Easy service thanks to fully automatic ash removal, optional pneu-
matic cleaning system and flue gas dust extractor
■ Highly developed safety devices ensure a safe and reliable opera-
tion
■ Individual planning of your system by our team of experts
■ Available as a complete ready-to-use containerised solution
