The preheater tower supports a series of vertical cyclone chambers through which the raw meal passes on its way to the kiln. To save energy, modern cement plants preheat the meal before it enters the kiln. Rising more than 350 feet, hot exit gases from the kiln and clinker cooler combined with fuels such as ground coal, petcoke, natural gas ...

1.1 Oxygen control. The oxygen at the calciner outlet is controlled through the calciner draft, in the same way as the oxygen at kiln inlet is controlled by the kiln draft. A normal target value for the oxygen after calciner (bottom cyclone exit) is 1 – 1.5 %.

How this would fit with any kiln electrification plans is unknown. However, one attraction of moving to an electrical kiln, for all of the projects above, is to cut out the 40 – 50% of a cement plant's CO 2 emissions that arise from the fuel that is burnt. Taking a kiln electric also makes CO 2 capture easier.

The ROTAX-2 kiln is the choice of the modern cement plant. The 2-base rotary kiln is a statically determined beam system, where the support load is always known. It is a shorter and wider kiln, with a reduced slope to maintain the material retention time, similar to a 3-base kiln. The larger diameter reduces the gas velocity and the dust recircula-

The Leamington Portland cement plant straddles Highway 132 in eastern Juab County. Martin Marietta Corporation completed construction of this 650,000 ton-per-year plant in 1980 to supply cement for the proposed MX missile program. The U.S. Government later scrapped plans for the MX system but there was enough regional construction to justify ...

Another efficiency lever is advanced analytics. One European cement producer achieved 6 percent fuel savings by creating self-learning models of a kiln's heat profile and optimizing the shape and intensity of the kiln flame. Future cement plants could leapfrog competitors by combining digital technology and more sustainable operations.

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.

A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln
