The Pyrotec boiler uses an underfeed stoker with a downward external grate and a moving burnout grate, thereby achieving the best possible combustion results. A charging auger guides the wood fuel into the combustion chamber, where it is pre-dried and degassed using an accurately controlled primary air
supply (grate combustion). On the external grate and moving burnout grate, the fuel is completely degassed. Accurately controlled secondary air is blown in to ensure complete combustion of the fuel. In doing so, the heat is released into the boiler's triple pass heat exchanger.

The Pyrotec boiler is a top quality construction for use under the toughest conditions. The inside of the combustion chamber is fitted out with high quality firebricks for greater durability. All grate elements are made of high quality, thick walled cast chromium steel and can withstand the highest temperatures. The Pyrotec boiler has a classic triple pass heat exchanger for maximum heat transfer and efficiency.

The advanced combustion technology in the Pyrotec achieves similar emissions ratings as a modern gas combustion system and keeps the release of CO and NOx to levels that correspond to those of an advanced heating system for fossil fuels. Furthermore, unlike oil and gas, wood is a carbon dioxide-neutral, renewable source of energy. When operated together with our digital, modulating output control, the Pyrotec boiler achieves efficiency levels of up to 92%.

■ High efficiency due to advanced combustion technology, triple pass
heat exchanger and modulating output control (modulation range 4:1)
■ Maximum heat transfer due to triple pass heat exchanger
■ High efficiency and extremely low emissions thanks to accurately
controlled primary and secondary air
■ Easy maintenance due to fully automatic ash removal, optional
pneumatic cleaning system and flue gas scrubber
■ Advanced safety devices ensure safe and reliable operation
■ Maximum system output due to high performance construction and
supply of all system components from one source
■ Automatic ignition device prevents idling and saves fuel (option – only
for fuels with water content of less than 40%)
■ Individual planning of your facility by our team of experts
