Submerged combustion melters and methods of feeding particulate material into such melters

摘要: Methods of melting particulate feedstocks in a submerged combustion melter employing an arrangement one or more burners emitting products into turbulent molten material. Operating the such that there is established region extending vertically from floor to splash region, between and head space ceiling, ceiling positioned above height H 2. Feeding feedstock through inlet ports, ports at 1 measured floor, where 1/ 2 ranges about 0.33 0.67. The SCM may have baffle region. A conduit be employed, having exit port
