Thermal Process Simulation: the Behaviour of Reactive Particles on Moving Grates Chuan Cheng

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.
