What is a local heating network and what is its purpose?
When operating a combined heating and power plant, heat will be generated in the cooling water and exhaust gas. Utilization of the waste heat increases the overall degree of energetic utilization of the biogas plant. Part of the heat generated is used within the process in order to heat the fermentation tanks, The largest part, however, may be supplied to external consumers. The heat generated in the biogas plant is then conveyed to the consumer via the local heating network. The revenue generated by selling the heat together with the CHP bonus enhance the profitability of the entire biogas plant.
