Method and system for preheating glass batch or ingredient(s)

摘要

The invention includes a method and system for heating one or more ingredients of a glass batch or the entire glass batch that is then used to make molten glass using waste hot gases (110) from a system for generating electricity using a drive for an electrical generator that is powered by a heat engine that exhaust waste hot gases (110) having a temperature of at least about 200 degrees C. At least a portion of the electricity generated can be used to power manufacturing plant equipment and the waste hot exhaust gases (110) exhausted by the heat engine, such as a gas turbine (106), is used in a static or dynamic heat exchanger (132) to heat the entire glass batch (120) or one or more of the ingredients of the glass batch, prior to feeding the glass batch (150) into a glass melting furnace (152).
