Enhancing Coal Feeding Systems for Optimal Kiln Performance
For cement plants that do not have advanced coal dosing systems such as Pfister, Coriolis, or Multicore, traditional coal feeding systems still dominate operations. These include: Venturi-Based Coal Transfer and Firing System, V1 – A successful project. FK Pump-Based Coal Transfer and Firing System, F1. FK Pump-Based Direct Coal Firing System, FD1 – Two successful projects. Challenges in Traditional Coal Feeding Systems In these setups, coal transport starts when the coal firing bin reaches its lower limit and stops when it reaches the higher limit. However, this method introduces several challenges: SFM Draft Variation: Sudden coal transport starts and stops create fluctuations in the SFM (Solid Flow Meter) draft, leading to inconsistent feeding. Bin Pressurization & Flushing: During transport, the coal firing bin gets pressurized, causing erratic coal flushing, which disrupts stable firing. Continuous monitoring and regulating is a headache for operators. ...
