The pellet or chip burner is seamlessly integrated into the client’s existing infrastructure. No major modifications to the heating system or the hot water/steam production network are required. The solution is based on a vertical semi-gasification process, which reduces the burner’s footprint, making it easier to retrofit into boilers, even in tight spaces. The ash generated from the biomass combustion is largely recovered within the burner itself, upstream of the boiler. This significantly reduces particulate emissions in the exhaust gases.
