A TEC awarded preheater optimisation contract at Turkish cement works

A TEC Production & Services GmbH has been awarded an engineering contract for the upgrade and efficiency optimisation of Çimentas Elazig’s preheater at its cement plant in Elazig in Anatolia, Turkey.

The scope of modifications comprises the redesign of all four cyclone stages, riser ducts and related equipment with the target to reduce the total preheater pressure drop by approximately 25 per cent and increase of the production capacity by at least eight per cent on a sustainable basis.

The project will be executed in two phases: the top and second stage modifications were completed in May 2014 and third and fourth stage in 2015. Phase one was successfully commissioned mid-May 2014, resulting in a sustainable production increase of eight per cent and a pressure drop reduction at the ID fan inlet of about 19 per cent compared to the pre-modification production rate.

Based on the phase one results it is expected that the pressure drop before the ID fan will be reduced beyond the target figures after completion of phase two, which will allow even higher production at less specific power consumption (kWh/t) on the ID fan than initially targeted, according to A TEC.
