A Method Of Protecting Of Grate Cars From High Temperature Exposure By Layered Heat Sink

Abstract: A method of protecting metallic machine parts of pallet cars from high heat is developed. These pallet cars are used in high temperature sintering furnaces. The said method comprises of layering lumpy materials, as hearth and/or side layer, having high loss on ignition values contributed by hydrates and carbonates. Sensible heat of circulating gas and hot agglomerates is absorbed by these layers in order to undergo dissociation reaction and therefore metal parts are protected better from heat. Also, because of high specific heat of water, water generated after dissociation requires high heat input for increase in temperature and therefore result in cooling of grate bar and other metal parts.
