Pyrotec Wood Fired Boiler
State-of-the-art underfeed combustion wood-fired boiler, 1330 to 4268 MBH.For wood fuels with max. water content of 50%
Grate firing at its best
The Pyrotec boiler uses a burner trough with an attached external grate and a moving annealing grate to achieve optimal combustion results. A feed auger moves the wood fuel into the burner trough where the fuel is pre-dried and gasified under precisely controlled primary air (underfeed combustion). On the external and the moving annealing grate the fuel completely gasifies (syngas). Precisely controlled secondary air is injected to fully combust the syngas and thermal energy is released into the boiler’s triple-pass heat exchanger.
Quality design and construction
The Pyrotec boiler is quality-constructed to handle the toughest of loads. The combustion chamber is lined with compressed firebricks with a high alumina content for added durability. All grate elements are made of durable cast chrome steel to withstand even the highest temperatures. The Pyrotec boiler features a classic triple-pass heat exchanger design for maximum heat transfer and efficiency.
Clean-burning and efficient
Equivalent in quality to modern gas combustion, the advanced combustion process of the Pyrotec keeps emissions of CO and NOx to levels comparable to those of modern fossil fuel heating systems. Plus, unlike oil and gas, wood is a CO2-neutral, renewable form of energy. Used with our digital, modulating-output control, the Pyrotec boiler achieves an efficiency of 85%.
