Electric arc furnaces are mainly used for melting steel for a range of applications, mainly by recycling steel scrap. The process exhaust gas from the melting furnace and the secondary emissions that are produced by the charging, tapping, slagging and post-treatment processes are collected.

The process exhaust gas from the melting furnace and the secondary emissions that are produced by the charging, tapping, slagging and post-treatment processes are collected.Emissions from the ladle furnace along with exhaust air quantities arising in the alloying plant resulting from the materials handling process, are either dealt with separately or incorporated into the combined primary/secondary dedusting plant of the electric arc furnace.
The Scheuch IMPULS filter is a high-capacity filtering separator that delivers outstanding cleaning performance combined with an excellent degree of separation. It is used for the dry separation of solid matter, primarily in the extraction of contaminants from machinery and the workplace, as a process filter in material recycling, or for conveyed material separation purposes.
Thanks to the specially shaped twin nozzles on the jet pipe, the pulsed free jet pulls along an envelope of clean gas from the primary compressed air as it makes its way to the injector. The two gas flows are mixed in the injector by means of pulse exchange an, at the same time, experienceing significant increase in pressure. This ensures highly efficient cleaning throughout the bag length and filter bags require cleaning less frequently.
Proven in practice for decades, the IMPULS cleaning system has become a byword for low operating costs:
A plant's ability to demonstrate a high level of safety and reliability is essentially dictated by its key components. The radial fan is one of the components at the heart of every extraction, dedusting, exhaust and flue gas purification, and pneumatic conveying system. It helps to meet customer requirements with a level of quality that guarantees fault-free operation and excellent performance between maintenance intervals.Drive designs:
Despite offering higher performance, this enhanced range incurs costs that are lower by around a third as compared to fans with a coupling drive – it also takes up less space. Even when combined with a frequency converter, it represents a less expensive alternative to fans with belt drives. The range has been designed and calculated in line with the latest findings in the field of fluid mechanics:
