在平板玻璃生产过程中,由于长期连续高温作业和平稳生产的工艺要求,所用燃料最好是高热值的天然气或燃料油。我国当前严格控制烧油,一般新建平板玻璃厂或者用不上,或者用不起这些高热值燃料,只好寻找适于气化的块状烟煤,自制发生炉热煤气。可是,这样的煤种在我国仅有大同、抚顺煤 In the flat glass production process, due to long-term continuous high-temperature operation and smooth production process requirements, the fuel used is preferably high-calorific natural gas or fuel oil. At present, China strictly controls oil-burning, it is generally not possible to use new flat-plate glass plants, or it cannot afford these high calorific value fuels. Instead, it has to find block-shaped bituminous coal that is suitable for gasification and self-produced furnace hot gas. However, such coal types are only available in Datong and Fushun coal in China.
