At the Ültje plant in Schwerte, waste heat from the roasting plant has been harnessed for other purposes. Since the conversion of the
The heat recovery system has priority in the central technology unit with a large buffer tank.
In summer, it supplies so much energy that the peak load boiler is almost always switched off. Even in winter, the residual heat from the stoves is enough to cover the heating requirements from Monday to Friday when the outside thermometer still reads above -5 °C. If other heat sources are to be integrated later in addition to the gas boiler, these can also be prioritized. If a CHP unit is used, for example, this could be prioritized over the gas boiler, as the controller sets the
heating systems on the basis of a priority and resource-optimized requirements plan, thus minimizing the use of fossil fuels.
When planning the new heating technology, Ültje had aimed to halve the amount of gas required - an expectation that was more than fulfilled: In fact, the plant now saves over 60 percent natural gas. The return on investment is therefore less than three years.
