Germany: 15 hectare greenhouse to be heated with waste heat

In 2012 VB Climate, member of VB Group, got the order of Agri4U BV for the heating of a greenhouse project of 15 Ha. in Wittenberg in Germany for the newly-built greenhouses of ‘Pieter van Gog Gemüse GmbH’ and ‘Wichard Schrieks Gemüse GmbH’. Because of a delay in obtaining the necessary permits, the start of the project has been delayed until spring 2013.

The greenhouse project will be heated by the waste heat of an ammonia power station, which is situated close to this greenhouse project. This ammonia power station supplies waste heat with a temperature of 62 ºC. To transport this waste heat from the power station to the greenhouse, VB Climate is constructing an in-ground pre-isolated steel transport pipe network with a diameter of 610 mm. The ammonia power station also supplies CO2, which is available in a 100% pure form and will be supplied through a PE-transport pipe to the greenhouse.

At this moment all underground transport pipes have been welded; from the factory to the greenhouses but also in the greenhouse itself. In the greenhouse a tube rail- and a grow pipe-installation will be made. These heating installations are designed in such a way that the available waste heat will be cooled down as much as possible. In the energy center a back-up boiler will be installed. In case of possible problem in the supply of heat from the power station this back-up boiler will provide the greenhouse with heat. In the energy center also a distributing unit (big manifolds) will be installed, that is prepared for future expansions.
