Name
cement production;cement, portland cement, 52.5MPa;new dry process, 2000 t/d;fly ash
Use advice for data set Users of this data set should consider the specific technological applicability of the Portland cement batch produced, which includes integration of fly ash. Attention should be paid to the system boundary that is defined as the cement production process only. The functional unit for the Life Cycle Inventory (LCI) results is specified as 1 ton of cement. When incorporating this data into larger LCA models, users should note recycling activities exclusion and adapt use-phase behavior modeling according to the specific construction context where the cement is applied.
Technical purpose of product or process This data set represents the production of Portland cement with a strength grade of 52.5MPa using the new dry process technology, which incorporates fly ash as a material component. The cement produced is commonly used in construction, for making concrete and other architectural and structural elements that require high strength material.

General comment Coal. The original text also provided the heat consumption (i.e. coal consumption) as 3,146,042 kJ. The low calorific value of coal is calculated at 23,301 kJ/kg for the air-dried basis. The coal consumption for each ton of clinker produced is 139.7 kg for burning and 2.5 kg for drying (here coal is assumed to be dried). Since the coal for drying accounts for only 1.76% of the total coal consumption, for the sake of calculation, it is assumed that all the coal is used for clinker burning process.
