In this article issues of efficient use of ferroalloys production waste to save costs are considered; energy efficiency of agglomerate production is calculated; sintering heat balance data are presented by a case study of Aksu Ferrolloy Plant. According to the annual economic benefits calculation the folowing results are obtained: due to аglogases recirculation, fuel saving is 1334.5 t.o.e.; due to reheating it is 1491 t.o.e.; due to installation of thyristor converters to the unit the annual energy saving is 1714000 kWh. Thus, it is identified that besides energy-efficiency measures during recycling of solid and gaseous wastes, the use of agglomerate increases IPF electric furnaces performance as well, decreases specific energy and reducing agent consumption which means the prime cost of finished products will be reduced.

One of the agent modern tasks is to ensure the cleanliness of the air basin. To ensure this, it is necessary to clean the combustion products of the fuel removed from the boilers after their cooling into the atmosphere from harmful substances, including nitrogen oxide.
