Lackeby sludge sludge heat exchangers for energy recovery in a biogas production plant
A series of three heat exchangers in a biogas plant. One unit heats the sludge from 45°C to 71°C (1.291 kW). The other two units are for energy recovery: 45 m³/h of digested sludge with a temp. of 71°C pre-heats raw incoming sludge from 35°C to 45°C (497 kW heat transfer). Note the limited footprint of the installation. The high performance Lackeby heat exchangers are compact and stackable for an even lower footprint. The hinged turning chambers assure easy access to the installation for inspection and maintenance purposes.
