Ibbenbüren power plant

The 838-MW hard-coal-fired unit generated electricity for the first time on 19 June 1985. For the production of electricity, high-volatile anthracite coal mined in the neighbouring pit requires a slag tap furnace. The Ibbenbüren slag tap boiler is the biggest of its type worldwide. Besides the primary fuel – Ibbenbüren anthracite coal – fuel oil is input as igniting fuel, fluidized bed lignite as support fuel and, as substitute fuels, meat and bone meal and sewage sludge are used.

Dust becomes construction material

The extensive plants for flue gas scrubbing consist of electrostatic precipitators (ESP) for dedusting, desulphurization plant und NOx reduction. In the ESPs, ash particles are separated from the flue gases, returned as fly ash to the slag tap furnace and melted. The resulting granules are used as construction material.

Gypsum for the construction-material industry

The sulphur dioxide emerging in the combustion of coal is removed from the flue gases in the desulphurization plant with a lime slurry and used as gypsum in the construction-material industry. NOx reduction works according to the process of selective catalytic reduction. The nitrogen oxides contained in the flue gas are converted with ammonia (NH3) and a catalyst into gaseous nitrogen and water vapour.

All flue-gas scrubbing plants are designed and operated so that the limit values demanded by statute are safely adhered to or undercut.
