ABSTRACT:
An improvement in the treatment of exhaust gases from glass melting furnaces is provided. Exhaust gases from such furnaces contain pollutants or contaminants in the form of condensibles which have been difficult to remove. To render these condensibles more easily removed and so that a higher percentage of them are separated from the exhaust gases, the exhaust gases are combined with other gases containing particles and specifically with gases containing inert batch dust from a source of glass batch. These gases contain relatively large particles which act as nuclei on which condensibles in the furnace exhaust gases can condense. The relatively large particles also serve as reaction sites on which reactable components in the furnace exhaust gases can chemically react to produce reaction products which condense more readily and are easier to collect. The larger particles and the additional condensation products from the combined gases can be more readily filtered out so that fewer pollutants or contaminants escape. The collected particles or dust can then be taken back to the batch source for subsequent use.
