District Heating Using Waste Heat

Waste heat that is recovered from sintering operations can be used to provide district heating to the residential buildings and offices.  This measure has limited application and is best suited for cold areas with high and regular heating demand. It has limited application potential for China, India, and the US.

District Heating Using Waste HeatCosts & Benefits

Parent Process: Sinter Plant
Energy Savings Potential

In Korea recovered heat from two sinter machines were used to provide 800 TJ/y district heating energy to 5000 inhabitants (NEDO, 2008. p. 18).  
CO2 Emission Reduction Potential

Fossil energies such as LPG/LNG are substituted resulting in reduced emissions.
Costs

Investment for the Korean plant was roughly $22.3 million.
