Patent ID: 10233105

Abstract:
Methods of melting particulate feedstocks in a submerged combustion melter employing an arrangement of one or more submerged combustion burners emitting combustion products into turbulent molten material. Operating the burners such that there is established a turbulent melting region extending vertically from the floor to a splash region, the splash region extending vertically between the turbulent melting region and a head space region, the head space region extending vertically between the splash region and the melter ceiling, the ceiling positioned above the floor a height H2. Feeding the particulate feedstock into the splash region through one or more inlet ports, the inlet ports positioned at a height H1 measured from the floor, where H1/H2 ranges from about 0.33 to about 0.67. The SCM may have a baffle extending from the ceiling into the splash region. A particulate feedstock conduit may be employed, having an exit port in the splash region.
