Prototype production of insulating material by the processing of
fly-ash from the Seversk thermal power station.
Objectives
Develop economically efficient technologies for the production
of various heat insulation materials from Seversk fly-ash.
Select the preferred technology for a plant at SCK, and prepare
samples of the proposed material.
Undertake tests on the thermal and other properties of this material.
Prepare a brief of work for the construction of the required facility.
Summary
To develop the technology to use waste fly-ash from the coal-burning Seversk thermal power plant,
in the manufacture of expanded silicate, mineral wool and other low-density non-flammable
construction materials with good thermal insulation properties. This has two benefits:
It recycles a waste product from the Seversk thermal power plant which is currently dumped,
with potentially harmful environmental effects. Recycling of this waste ash will become increasingly
important when the proposed co-generation plant becomes operational, following the closure of the
nuclear power station at Seversk.
It will enable the manufacture of materials with good sound and thermal insulation properties
required by the local construction industry.
A range of technical and commercial options will be invesigated, and a decision made on
the optimum specification for a plant to supply this market.
This work will be undertaken by SKC in collaboration with a number of University and Private
Sector organizations in the Tomsk Region.
Cost
Total cost of the project is £280,478. The DTI is funding a contribution of £120,000.
