Abstract

Batch material for glass or ceramic is mixed with solid or liq. fuel which is combusted in pre-heating zone; ash and unmelted batch are passed to 2nd stage to melt batch, melting is then completed under oxidising conditions. Powdered material is heated so that source of O2 is supplied to combustion zone; gas and solid flows are co-current. Constituents not melting below 900 deg.C are mixed with fuel which is combusted to give 900 deg.C; mixt. of batch and ash is passed to 2nd zone and mixed with lower melting components and melting then completed. Batch for 1st zone includes alkaline earth carbonates which become calcined.
