The present invention relates to glass melting
furnace there is usually provided a plurality or
5 series of regenerative ports and the gas is ordi
narily supplied to the furnace by burners placed
adjacent to and communicating with such ports.
The gas fuel, as it enters the furnace, unites with

port it to the vault 22 above the level of the 5
glass or glass producing material 23.
Also communicating with each port it ‘are fuel
intake ports 24, 25 and 28 respectively, arranged
in a. single plane on the bottom 21 of passage ii.
The ports 24 and 25 are provided with valved 10
gas fuel supply pipes 28 and 29 and the central
the heating chamber of the furnace.
In a glass melting furnace it is very important or larger port 26 is provided with oppositely dis

Since the openings of the fuel intake ports
or manifolds be such that a su?lcient volume of ‘

in the form of a relatively ine?lclent turbulent are faced toward the area to be heated, the fuel
gas is directed on- streams parallel to the air

as are the openings of the air intake ports. In the drawing:

velocity and intensity of the ?ame entering the 25
furnace can be effectively controlled to meet
