Description of the refractory concrete LACFIRE of the combustion chamber and grate of boilers PYROGAS




PYROGAS boilers are modern hotwater gasifications boilers burning wood and wood briquettes with high efficiency to satisfy the condition of EcoDesign, Class 5 of the EN 303.5, Austrian national deviation under Article 15a, German National deviation BlmSchV, Stufe 2 valid from 1.1.2017, Slovenian EKOSKLAD deviation, standards for Switzerland, Denmark and it is possible to use for their purchase the non-repayable financial contribution from government as such the The new Green Investment, Kotlíková subsidy, Green homes, etc.. Boilers are certified by the notified and accredited testing laboratory under the responsibility of the EU and registered in the German DIBt.


Corundum refractory concrete LACfire

Fireproof combustion chamber LACFIRE 1800/20 SiC with the addition of silicon carbide due to its robustness and segment structure provides a high thermal inertia and thermal stability, long life and easy interchangeability of the most thermal exposed parts independently of the others, thus contributing to cost savings in the long-term maintenance. The resulting wood gas is burned completely in a firebeton chamber at temperature up to 1200 ° C with a direct efficiency of the 91%.

LACfire 1550/30 1450 °C


Combined mullite refractory concrete with the addition of silicon carbide to increase hardness. Shaped blocks made of this refractory concrete material excel in their strength, small linear changes, and resistance to abrasion. Because of this, they are often used in combustion boilers fed with alternative fuels such as wood pellets, wood chips, and biomass.
