Repowering Pipe system Mixer replacement without tank emptying

Repowering mixers ... an opportunity to increase efficiency Repowering mixers In Germany there are currently around 7,000 biogas plants in operation with approx. 30,000 mixers working in their digesters. The estimated average power consumption per operating hour and mixer is approx. 10 kW/h. With an annual operational time of 25 % this gives an incredible power consumption of 657,000 MWh. Assuming an electricity price of EUR 0.155 per kWh, the cost is approx. EUR 100 million/year. If it is possible over the next few years to convert existing biogas plants to highly efficient mixer...

„Repowering Pipe“ system Mixer replacement without tank emptying Repowering Pipe“ principle The greatest obstacle in the path of efficient mixer technology up to now has been the need to empty digesters for installation. As an operator you are aware of the consequences of having to bring the process back to a stable level after refilling. „Downtime costs amounting to thousands of Euros have up to now been the re
