37 Laboratory test results of PFC cassettes Laboratory test results of PFC cassettes A clear reduction of pressure loss can be seen. CFD results and Measured results have similar trend. However, measured pressure loss is higher than the CFD. In the range 0.5 to 2.0 Nm³/m²/s there is ca. 45 % reduced pressure loss as compared to current PFC² Cassette. The new static grate design was optimized from 12.5° to have an increased inclination of 15° and eliminated steps on the surface to enable ‘sliding’ movement of clinker from static grate on to the moving lanes. Quick & smooth transition of clinker from static grate to moving lanes. No upward COOLER STATIC GRATE DESIGN FACTORS Keeping the heat within the kiln line is the mayor requirement of a static grate. A rapid cooling ensures a higher state of heat recuperation. In the following graph, an optimized temperature profile and a standard pressure profile of a PFC is shown. step where plates meet. It allows sliding down of clinker pile on static grate which gives a benefit in “Snowman” reduction. The optimized slot gap ensures better aerodynamic at entry point. Resulting in less pressure loss.
