Assessment of the theoretical heat recovery potential from wastewater in sewer systems

Original language description

The present paper deals with the assessment of the theoretical potential of wastewater in the sewer system for heating of buildings. A classification scheme of the suitability of sewers for the installation of heat exchangers involving criteria like theoretically available heat, sewer diameter, number of the heat exchanger parallel modules in the sewer cross-section, and hydraulic conditions (hydraulic capacity of the sewer, pressurized flow) was developed. First, individual sewers in the pilot catchment were assessed based on monitoring the flow characteristics and wastewater temperatures and on pipe flow modelling. Second, connectivity of the suitable and partly suitable sewers was examined with respect to the length necessary for the installation ofthe heat exchanger with the minimum required power of 100 kW. For the continuous sewer sections, the maximum potential power was calculated. The presented approach is generally applicable, however, for other heat exchanger types and othe
