Traditional rotary kilns produce cement clinker.After detection, the gas flow rate of rotary kiln was between 32137~43251Nm3/h. When utilizing the data set, users should pay attention to the specific production rates provided, which are 65kt/a and 81kt/a for the associated sulfuric acid plant and cement clinker production, respectively. The gas flow rates between 32137-43251 Nm3/h should be considered within their emission modeling. Ensure that the system boundary, which includes raw material input, calcination processes, and product and waste gas discharges, is appropriately integrated into the life cycle assessment to accurately ascertain the environmental impacts of the clinker production.
