GRETA - Value adding heat recovery - main report

The main report summarises the results of the case studies and for the waste heat sources for two heat demands. The waste heat sources are cooling systems for induction furnaces and compressed air, and heat recovery from goods, sand and heat treatment furnaces. The heat demands are district heating (incl. internal comfort heating) and heat-driven power generation. The case study at Baettr shows good availability and temperature in both sand and goods, but the sand is easier to access than the goods. The case study at Smålands stålgjuteri shows good availability, accessibility and temperature for recovery of exhaust gas heat from the heat treatment furnace. Both case studies show that the foundry's internal comfort heat demand is poorly matched to the supply in terms of availability. District heating is a good alternative if it is accessible (distance and interest from the utility). The supply of heat-driven power plants is limited, the electrical efficiency can be expected to be 5-10% of the supplied drive heat.
