Biogas burners
Biogas is the result of anaerobic processing of urban waste, which is produced naturally at any waste site, and features a high methane content (>50%) and calorific power of 4,700 Kcal/Nm3. The use of this gas in the ceramics industry is very cost effective. It is very likely that proliferation of biogas generation plants will provide more ready access to this fuel.
This is necessary for those cases when the supply of biogas is irregular or unreliable. The latter fuel is required to make up for inconsistent supply of biogas
