General Application Overview for ILTEC in Metallurgical
Plants
Basically, the ILTEC technology opens new windows for metallurgical furnaces for
all the metallurgical fields of interest in both iron and steel technology as well as
non-ferrous industry (Fig. 6).
Whenever water-cooled components are prevailing, the water cooling can be substituted by a closed loop ILTEC system and IL-B2001. The same amount of heat
can be removed, and the prevailing piping and instrumentation system can be used.
Hence, with the same cooling effect, a perfectly safe operation mode can be achieved.
Research activities, and even more commercial operations, have proven that the ionic
liquid IL-B2001 and the ILTEC Technology can lead to an industrial change regarding
safety standards (Fig. 6).
Increasing Safety
Over the past years, more than 200 incidences with fatal damages in terms of health
and equipment had been officially reported [9]. However, the real number is even
higher. The elimination of the water in critical areas of furnaces, such as the cooling
of metal bath area of smelters, will not essentially eliminate the risks for break downs
but it greatly diminishes the consequential damages caused by explosions. Typical
applications for improved safety are the furnace tapping areas, sidewall cooling, and
cooled parts, which are exposed to the hot face and liquid metal.
