Thermal Process Simulation - The Behaviour Of Reactive Particles On Moving Grates

The moving grates, or travelling grates, are widely used in industries. In this book, the physical and chemical phenomena in the gas-solid systems on the moving grates were simulated and discussed. The program LEPOL simulated the drying, pre-heating and partial calcination of limestone particles on a travelling LEPOL-Grate, which was built in front of a lime rotary kiln. The purpose of the research was to show how to decrease the average or peak temperature of the hot gas when it reaches the LEPOL-Grate, in order to protect the grate material from overheating. Another program, CLINKER, simulated the rapid cooling down of clinker particles on a similar moving grate. The aim of the investigation was to find some methods to prevent the fluidisation of smaller clinker particles, which limits the product throughput.
