Energy efficiency optimisation by
Industrial process and municipality integration
B Kjellström, G Keikkala

The mining industry, including ore extraction, mineral
processing and process metallurgy have a high energy
consumption. The energy is used for the product as latent heat,
for re-circulation in the process or becomes waist energy that
can not be used in the process.
These industries are located close to the mineral deposits with an
adjacent town where the employees of the industry are living.
Many of these towns are heated by district heating.
The onshore industry in Murmansk Oblast and adjacent areas are
dominated by these kind of industries. The cities have district
heating. There are almost no energy co- operation between the
industry and the cities. This study aim to optimise the energy
system by integration of the industrial process and the
municipality.
The power plant Lulekraft AB and Luleå
Energi AB energy integrated with the
local steel company SSAB and the town of
Luleå
In some cities in Sweden there are a energy co-operations. The
experiences of these co-operations is a part of this study. One
part of the study aims to show on possibilities to use more of the
waist energy in the community that not are needed for heating
for example needs for cooling of buildings, offices, computers
and processes.
The research is funded by the Swedish National Energy Administration.
