The burner system of Line 5 at the Krasnoyarsk cement plant in Siberia has been retrofitted from a direct-firing to a state-of-the-art indirect-firing system, courtesy of KHD Humboldt Wedag. The burner exchange project, primarily implemented to meet tighter emission regulations, yields further potential benefits for this wet-process plant.

The Krasnoyarsk cement plant is located within the city limits of Krasnoyarsk in Siberia. It consists of three kilns with a combined capacity of 662,000tpa. The wet-process Kiln Line 5 is 4 x 150m with a clinker capacity of 804tpd.
Until 2018 thermal energy was supplied by a direct-fired ball mill burner system. The replacement of this burner system was imminent due to more rigorous emission regulations, particularly NOx, which could not be met with the existing burner.
