Depending on the variety and process, plants require 60-130 kg of fuel oil and 110 kWh of electricity to produce each tone of cement. For every tonne of cement made, the process releases approximately a tonne of carbon dioxide. Around 50% of emissions come from producing clinker, 40% from burning fuel and 10% from electricity …
Oxyfuel technology replaces ambient air in the clinker production process by introducing pure oxygen into the front zone of the cooler. Since the nitrogen content of the air is no longer present, the CO 2 concentration in the kiln exhaust gas can be increased up to . CO 2 is thus better isolated and more suitable for later use and storage.

Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2). In the next step of the so-called clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2 ...

Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making. Raw material preparation and cement making are the main electricity-consuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant.
ground and fed into the process at the top of the cyclone tower. The process continues with the material being preheated in the cyclones and calciners, entering the riser duct and flowing into the rotary kiln. After reaching the maximum temperature at the lower end of the rotary kiln, the clinker is cooled in a clinker cooler.
The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
As a consequence, the best available technique (BAT) levels for new plants and major upgrades are 2,900–3,300 MJ/t clinker, based on dry process kilns with multistage preheaters and precalciners ( European Commission, 2010 ). As the change in cement kiln size is difficult, waste heat recovery may play an important role.
Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of blended cements) and deploying innovative technologies, such as carbon capture and storage and …
scenario by 2100 reported by IEA (Reference Technology Scenario, RTS) according to which average global temperature will rise by 2.7 oC. Since the PC-clinker is a primary product of concrete construction, it is logical to evaluate the "carbon footprint" at all stages of its life cycle, from annealing process to producing a concrete frame
A simple mathematical model is presented for clinker production via a pyroprocessing unit consisting of serial flow preheater cyclone stages, a precalciner, a rotary kiln and a clinker cooler. The model equations are based on steady state material and energy balances for solid and gas phases around each piece of equipment. The …
