Many industries in the world and the iron and steel sector have
focused on energy saving in order to stay in the industry and remain
competitive in competition. Energy saving is an important way to
increase predictable gains and to reduce dependence on cost and
energy resources. Economically, increase of energy productivity is
more attractive than investing for putting into use extra new energy
sources. Blast Furnace Top Pressure Recovery Turbine System (TRT)
which is taking advantage of pressure difference of Blast Furnace Gas
by converting mechanical energy to electrical energy which is tool of
energy saving and using at iron and steel industry in Brasil, China,
Germany, Italy and South Korea and also begin to used in our country
recently.
Since the industry and iron and steel sector uses 15% of the
world's energy demands, energy saving in these sectors is of great
importance. The Turkish iron and steel industry, which has recovered
faster than the developed countries in the global crisis, has become the
9
th largest producer of crude steel sector in the world and the 2nd big
producer in the Europe.
In this study, it was investigated importance of TRT system
around the world, returns to sector, the technological advantages and
numerical statistics of the countries having the TRT system. It was
carried out feasibility study during the installation time and calculated
installation and operation costs, total costs and pay-off period about
TRT system of a sample factory.
