Turning coal into coke, a raw material used in steelmaking, is a complicated and dangerous process, as evidenced by the explosion Wednesday that injured 20 people at the country's largest coke plant. But those familiar with the industry say it can be done safely. "When people ask me, is this is safe place or is this a dangerous place?
Pentalin has operated the Mzimkhulu Coal Crushing and Screening plant, one of our largest operations, since 2018 following a successful five-month construction period. The plant is capable to process up to 4,2Mtpa of ROM and has a nameplate capacity of 650 tph. The coal sampling station is accredited by ESKOM.
Process monitoring and fault diagnosis (PM-FD) of coal mills are essential to the security and reliability of the coal-fired power plant. However, traditional methods have difficulties in addressing the strong nonlinearity and multi-modality of coal mills. In this paper, a novel multi-mode Bayesian PM-FD method is proposed. Gaussian …
Coal is still used in approximately 90% of cement plants globally to deliver the energy needed for the heat inside the kiln. Online coal analyzers using PGNAA technology are used to control the coal blend to a specific GCV in addition to the ash value of the coal as this adds raw materials to the process as well.
