Abstract
Method and apparatus for direct coal firing of glass tank furnaces wherein pulverized coal entrained in an air stream is impelled through a nozzle into the furnace and combusted in the atmosphere directly above the melt in a glass furnace, to form a luminous flame, the direct coal firing preferably being used in conjunction with supplementary conventional heat sources.
Claims7
A method for producing molten glass from a glass batch comprising:
- placing a quantity of glass batch material in a glass tank furnace, and combusting fluidized, pulverous coal entrained in an airstream to produce a flame in the glass tank furnace immediately above the batch material and resulting molten glass, whereby glass is produced utilizing pulverized coal to direct fire the glass tank furnace.
A method for producing molten glass from a glass batch comprising providing a quantity of glass batch material in a glass tank furnace, generating first and second airstreams by means of blowers outside of the glass tank furnace, dispensing pulverous coal at a predetermined rate and entraining the coal in the first airstream, mixing the first airstream containing the entrained coal with the second airstream adjacent a burner directed into the glass tank furnace, projecting the entrained coal in the combined airstreams through the burner and into the glass tank furnace, and combusting the pulverous coal within the glass tank furnace immediately above the glass batch material and resultant molten glass in the form of a luminous flame.
