A unique training program on process measurements and calculations for cement plant has been designed with the following goals and objectives Enabling you to use portable instruments like anemometer, pitot-tube, temperature and pressure meters, tachometer, gas analyser for process measurements and cross-checking Measurement System Analysis.
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At A, the raw meal largely decarbonates at B, the temperature is 1000 C 1200 C and intermediate compounds are forming and at C, the burning zone, clinker nodules and the final clinker minerals form.
The cement production process is energy intensive both in terms of the thermal energy firing the kiln, drying and De carbonation and electrical energy for driving the numerous drives within the process line. The average specific power consumption of the case study plant was 111 kWhton of cement with an average peak demand of 9.7 MW.
