Abstract
A method and apparatus for glass manufacture is described having batch preheating and reduced pollution emission. The apparatus includes two modules containing pelletized glass and/or cullet. One module functions as a pelletized glass preheater, and the other as a filter for removing pollution emissions from furnace exhaust gases. The modules are switchable, such that the preheating module can be converted to a filter module, and the filter module converted to a preheating module, thus allowing periodic cleaning and routine maintenance.
