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 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 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 exhausted by the heat engine, such as a gas turbine, is used in a static or dynamic heat exchanger to heat the entire glass batch or one or more of the ingredients of the glass batch, prior to feeding the glass batch into a glass melting furnace.
In a method of preparing a glass batch for a glass melting furnace comprising weighing out at least one major ingredient and one or more minor ingredients, all ingredients comprised of particulates, according to a desired recipe, mixing the at least one major ingredient and one or more minor ingredients together thoroughly and feeding the mixed batch to the glass melting furnace, the improvement comprising using waste hot exhaust gases from an electrical generating system comprising a heat engine to heat one or more of the ingredients or to heat the entire glass batch by passing the waste hot exhaust gases through a particulate heating device prior to feeding the batch into the glass melting furnace.
In a system for preparing a batch for a glass melting furnace comprising a batch preparation system and a means for feeding batch into a glass melting furnace, the improvement comprising one or more ducts for carrying waste hot exhaust gases from an electrical generating system comprising a heat engine to a heat exchanger for preheating or one or more ingredients of the glass batch, the heat exchanger that will transfer more than 50 percent of the heat energy in the waste hot exhaust gases above ambient temperature in the hot exhaust gases to a particulate material comprising at least one ingredient of the glass batch, inclusive of the entire glass batch.
In a system for preparing a batch for a glass melting furnace comprising a batch preparation system comprising a scale and a mixer and a means for feeding mixed batch into a glass melting furnace, the improvement comprising one or more ducts for carrying waste hot exhaust gases having a temperature of at least about 200 degrees C. from a heat engine in an electrical generating system to a heat exchanger for preheating the glass batch, the heat exchanger transferring more than 50 percent of the heat energy above ambient temperature in the waste hot exhaust gases to the batch prior to feeding the batch into the glass melting furnace.
