Boiler advantages

Design and user benefits of PYROGAS boilers

• PYROGAS boilers are hot-water gasification boilers for pyrolytic combustion of lump wood and wood briquettes with high efficiency, meeting the Ecodesign conditions, class 5 according to EN 303.5, and depending on the verification, also the Austrian national deviations according to Article 15a, the German national deviation BlmSchV, Stufe 2 valid from 1.1.2017, the Slovenian deviation Ekosklad, standards for Switzerland, Denmark and it is possible to use non-refundable financial contributions as part of state support such as New Green for Savings, Boiler Subsidy, Green for Households, etc. The boilers are certified in notified and accredited testing laboratories within the scope of the EU and registered in the German DiBt.

• The refractory concrete combustion chamber LACFIRE 1800/20 SiC with silicon carbide admixture, thanks to its robustness and segmented design, ensures high thermal stability and inertia, long service life as well as easy replacement of the most thermally exposed parts independently of the others, which contributes to long-term maintenance cost savings. The resulting wood gas is perfectly burned in the refractory concrete chamber at temperatures up to 1200°C with a direct efficiency of 90%.

• In the massive cast iron grate surface there are LACFIRE refractory concrete accumulation inserts ensuring constant burning of the coals until they are completely burned out and the burnt fine ash subsequently falls into a separate ash pan. This design solution allows ash to be removed from the boiler during full operation. This solution both contributes to a more perfect release of flammable gases from the wood and protects the boiler from direct contact of the coals with the hot water surface, which has a positive effect on the boiler's service life.

• Separate rear combustion from the ash pan area and turbulators (flue gas brakes - option) significantly reduce the risk of ash swirling and its share in the flue gas, while the ash falls into a separate ash pan section.

• The design of the primary nozzle ensures a reliable combustion process of wood and wood briquettes.
