8,300 operating hours of the wood gasifier in its first year
The HKA 30 biomass CHP at the Klein sawmill commenced operations in December 2012. The system reached 8,300 operating hours in its very first year, with a woodchip consumption of 2.5 to 3 sq m a day. The heat is discharged out of the cogeneration plant through a heat exchanger with an output of approx. 80 kW, and fed into a 10,000-litre buffer storage tank. The excess energy is extracted via a blower and used to dry woodchips. The blower can operate with an output of up to 4 kW.
Heat for drying wood and heating buildings
The system’s heat is used to heat three residential buildings, the mill premises and a wood-drying facility.
This sawmill in Lower Bavaria has been manufacturing construction timber and pallets since 1910.
