EVRAZ NTMK has put into operation a new waste heat recovery system designed by KALUGIN JSC

The iron and steel works EVRAZ NTMK (Nizhny Tagil, Sverdlovsk region) has put into operation new systems of heat recovery at blast furnace no.5 and blast furnace no.7 thanks to which clean blast-furnace gas will be preheated at Kalugin hot stove systems (KSS).
According to General Director of the company implementation of new heat-exchangers based on thermosiphons will enable blast-furnace men to decrease or to refuse completely using natural gas as a high calorific additive to blast-furnace gas and to save fuel resources significantly. Moreover, due to implementing new process engineering solutions, appearance and influence of moisture on stove refractories will be entirely excluded, - noted Ms.Kalugina.
