Abstract:
A method of melting materials comprising the steps of:providing a melter body having (i) a batch injection portion including a batch inlet port, (ii) a batch melting portion including a batch melting chamber adapted to receive batch materials from said batch injection portion, and (iii) a molten materials delivery portion including a molten materials outlet port;injecting batch into said batch melting chamber through said batch injection portion; andproducing a vortex flow pattern in said batch melting chamber by injecting (i) heated products of combustion from a primary fuel supply and a primary oxidant supply, (ii) a fuel from a secondary fuel supply, and (iii) excess oxidant from said primary oxidant supply into said batch melting chamber through a common jet stream port in said batch melting chamber, wherein fuel and oxidant within said vortex flow pattern react within said vortex flow pattern and said excess oxidant is introduced such that approximately four times the amount of excess oxidant over the stoichiometric requirement for oxy-fuel firing is introduced via said primary oxidant supply.
