Trial operation by Bioenergie Niederösterreich

Regional heating supply for industrial buildings in Wöllersdorf

Bioenergie NÖ reg.Gen.m.b.H. as operator could team up the companies Iveco, Plecher Planen, AKE Knebel & Forster und H.T.B. Handel-Transport-Beteiligungs GesmbH with an underground district heating network to supply these companies eco-friendly and regional with heat in Wöllersdorf.

EcoProjekt was assign as general engineer for the design and as building control for the industrial wood-chip heating system. Wood chips are a carbon-neutral bio-fuel which has high security of supply as domestic energy source. Wood chips are delivered from the nearby black pine forest and stored in a 120 m³ bunker above-ground. This lasts for 14 days when operating with full load.

The plant aims for local supply of heat and warm water to industrial building in the area of Wöllersdorf. The current trial operation produces 600kW power and feeds the 4 connected companies. The biomass heating system is expandable in cascades and is able to supply further companies in the area with district heating pipes.

Covering power peaks is very expensive and high energy input is needed. Therefore, a buffer has been integrated into the system for economic reasons. Performance fluctuations can be equalised for example in the summer, when mainly warm water is produced.

The construction of the bio-mass heating system has started in October 2013. Since the beginning of December 2013 the trial operation has been running.
