Lime Kiln Advanced Process Control OptiLime Lime Kiln Process presents one of the most challenging measurement and control solutions in the Pulp and Paper mills The complex dynamics and multi-variable nature of the lime kiln process, with its non-linear reaction kinetics, long time delays and variable feed characteristics, make the process inherently difficult to operate efficiently...

Measurement and Simulation of Lime Calcination in Normal ...

The model is used to simulate the temperature of the gas and the solid, the lime-burning degree, the pressure drop, and the heat loss by kiln shell. Operating conditions, such as kiln throughput, energy consumption, and stone size, are also investigated by the model. Experiments were carried out to measure temperatures in industrial kilns.

Temperature Measurement for Cement & Lime Kilns

Most modern kilns have a 4 to 5 inch inside diameter by 4 to 5 foot long target tube in the sidewall of the kiln where monitoring mid-kiln temperature is critical to ensure kiln integrity. A PSC Non-Contact Infrared (IR) Pyrometer is recommended for measurement reading during each rotation of the kiln.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
