Höganäs says that its PM plant has been able to reduce its energy consumption by 2.5 million KWh and direct carbon dioxide emissions by about 350 tonnes per year.
‘When we were building a new furnace, we saw synergy effects that made it possible to implement the measures at a lower cost than before, said Magnus Pettersson, energy coordinator at Höganäs. ‘When we also received our application to the Energy Board at slightly less than 30% of the additional cost, it was within reach.’
Höganäs replaced 16 old industrial fans with a modern fan system, which reduces the need for electricity. The system also makes it possible to preheat the combustion air to the furnaces, which reduces the need for natural gas, the company said. In addition, the company rebuilt the plant so that surplus heat from production can be used to reduce the need for district heating during parts of the year. In January 2020, installation for delivering heat to the internal district heating network was completed and in May 2020 delivery will start.
