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.
