Two new generation burners were installed at the Nowiny (Poland) cement plant in 2009 and 2010. The new burners allow for better control of the clinker burning process and improved use of higher amounts of alternative fuels.
Together with the new burner installation, the primary air fans for flame shaping were replaced with higher performance rotary lobe blowers. The burner and primary air blowers at kiln no. 2 were started up between end of August and September 2009. Kiln no. 1 underwent an identical process during the winter shutdown, taking advantage of the experience gained with kiln no. 2.
The Nowiny cement plant has been using tires and fluff as alternative fuels for several years, feeding them into the kiln inlet or through the main burner. Using more alternative fuel generates significant cost savings in the clinker burning process and protects the environment because the high temperatures and alkaline reactivity of the limestone reduce emissions of sulphur compounds, despite the use of waste plastic and paper.
