TRT (Top pressure recovery Turbine) will be installed in Poland at TAMEH power plant in Dąbrowa Górnicza to produce energy in an ecological way without emissions of dust or gases.
Two turbines (each weighing 81 tonnes) resembling wind mills in operation, will be assembled to modernised installation of the blast furnace gas. The turbines will be aligned to two blast furnaces operating in Dąbrowa Górnicza. Both turbines have arrived in Dabrowa Górnicza and are being assembled. The turbines travelled a long distance. Starting from Japan, where they were produced, they travelled through China, Singapore,Saudi Arabia, Greece and Germany before finally reaching Gdańsk. From Gdańsk, they were then transported to their final destination, Dabrowa Górnicza by land. It was a highly unusual transport, to let the turbine in, part of gate no 4 had to be disassembled.
Before TAMEH power plant was producing energy out of blast furnace gas, the pressure of which had to be reduced. ArturŁój, project manager at the Investment Office in TAMEH POLSKA explains: "Now at the same place where we used to reduce gas, we will install TRT, powered by compressed blast furnace gas to produce energy. TRT technology is completely emission free, it will not impact the environment.
"Each turbine is 12,5 MW, so together they have the capacity of 25 MW. In order to produce the same amount of energy from natural resources, it would be necessary to burn 45 thousand tonnes of coal annually, so an equivalent of 900 wagons. The emission would amount to 90 tonnes of SO2 and NOX and 9 tonnes of dust."
The TRT turbines are the first of its kind to be installed in Poland. There are a few hundred of them across the globe, mainly located in Asia. In Europe, there are only a few dozen of them. In Dąbrowa Górnicza power plant, the turbines will increase the amount of generated energy without cost increase and without emissions.
The turbines placed in containers 4.5 metre wide; 5 metre high and 8 metre long are just being assembled. After completing the works, it will be necessary to install generators, pipelines,and connect turbines to the blast furnace gas installation.
"We have adjusted the assembly dates to the schedule of the blast furnace operation in order to take advantage of planned stand stills and not to disturb the work flow." said Artur Łój.
The investment is to be finalised by the end of this year. The general contractor is the consortium of Primetals and Eko Energia from Kraków, but apart from them, many companies from the region are involved in the project. Every day, approximately 100 people are working at the construction site. The value of the project exceeds PLN 100 m.
