Turbines to produce clean energy at TAMEH power plant

For the first time in Poland, two top pressure recovery turbines (TRT) will be re-using high pressure flue gas from the top of the blast furnace to reduce ArcelorMittal’s carbon footprint and its energy bill, while producing emission-free energy for TAMEH power plant in Dąbrowa Górnicza.

Two 81-tonne turbines, made in Japan, shipped in containers 4.5m wide, 5m high and 8m long, are being assembled before being mounted to modernised blast furnaces operating in Dąbrowa Górnicza, Poland. The turbines will increase the amount of energy the power plant generates, at no extra cost and without emissions.

Producing electricity using TRT technology is as sustainable as wind power, but much more efficient. The two new TRTs’ total capacity of 25 MW is roughly equivalent to the output of eight to ten land-based wind turbines. To produce the same amount of energy from coal, it would be necessary to burn 52,000 tonnes of it annually.. The associated emissions would amount to 90 tonnes of sulphur dioxide and nitrogen oxides and nine tonnes of dust.

TRT technology uses high-pressure gases (known as flue gases) which are collected at the top of the blast furnace to drive very efficient electricity generators. The TRT turbine generates energy by exploiting a known property of all gases.

The investment, to be finalised this year, is worth over PLN 100M. The project’s general contractor is a consortium comprised of Primetals and Eko Energia from Kraków.
