Environmental Guidelines for Glass Manufacturing

2018-8-5 · Cold top electric furnaces that operate with coverage of the melt surface by raw material feed release very little particulate matter as the blanket acts as a filter to prevent the release of particulate matter. Some releases of particulates will take place when tapping but furnace releases should be in the order of 0.1 kg/t when operated this way.
