OREANDA-NEWS. OAO Koks continues the assembling of airway awnings of the ecological system at the ram №4. This is the second attempt of Serbian firm "GOSA - FOM d.o.o" to install the ecological system at the ram №4. Such installation is new for OAO Koks. It is supposed that the usage of bag filters will reduce dust emission, which regularly occurs during the coke giving out the furnaces, thereby the plant will diminish the negative environmental impact. This project is the part of the realization of the environmental policy OAO Koks. The OAO Koks specialists were not satisfied with the first installation of the system: the effectiveness was too low. At present the utility suppliers "GOSA - FOM d.o.o" are eliminating defects, installing the awnings of bigger diameter and increasing the coverage of the suction device surface. The first tests will be conducted early next week.
