Device and method for increasing energy generation to cogeneration plants in the exhaust flow of glass melting and refining processes in transverse-fired furnaces with regenerative heating units

摘要

The object of the invention is therefore to provide a method and a device for increasing the energy production of combined heat and power plants in the exhaust stream of glass melting and Leuterprozessen in transverse flame tubs with regenerative heating in the flat glass production, especially for the electric energy, in which a high degree of energy production is possible. According to the invention, at least one heat exchanger 3a, 3b is connected to a superheater 4 and this to a turbine 5. In this case, the heat exchanger 3a, 3b, the exhaust gases of the standpipe 2 and the exhaust gases of the melting tank 1 as a common exhaust gas flow 6. The method for increasing the energy production of cogeneration plants by means of in the exhaust stream 6 of glass melting and Leuterprozessen in transverse flame tubs 1 with regenerative heat exchanger heat exchanger systems passes the common exhaust stream 6 of the exhaust gases of the stand-off sump 2 and the exhaust gas of the melting tank 1 by at least one heat exchanger 3a, 3b. The heated in the heat exchange process medium is at least one superheater 4 and is supplied superheated at least one turbine 5, which passes this at least one turbine 5 driving. The field of application of the invention is the energy production in glass production.
