regenerative glass furnace

Regenerative heating was one of the most important technologies developed during the Industrial Revolution when it was used in the hot blast process on blast furnaces. The object of the invention is to provide a device and a method for furnace pressure stabilization with changing volumetric amounts of flue gas when changing firing during glass melting and refining processes in transverse-fired furnaces with regenerative heating, in particular for flat glass production. Regenerative glass furnaces are one kind of glass furnace that aims to do just that. Due to its high flexibility and its low energy consumption the regenerative end fired furnace is the working horse of the glass industry. Even more rare are recuperative end fired furnaces with ceramic recuperators, which HORN would not recommend due to short lifetime of the heat recovery system. Falorni Tech PROVIDES a glass melting furnace from small capacity to large capacity units for GLASS PACKAGING PRODUCTION. GENERAL. First, the composition of glass furnace gases and carryover is presented. End port furnaces are generally used by the container and glassware industries for the melting of soda lime glass. Each line is designed for maximum longevity, optimum efficiency and with the environment in mind. While in one chamber the combustion gases pass through the checker and enter the furnace in the other chamber the checker is heated, or regenerated, with the outgoing hot exhaust gas. In regenerative ovens, firing is carried out in cycles. The glass furnaces are nowadays conceived with regenerative systems to take advantage of the residual heat from the combustion exhausts in order to increase the thermal efficiency of the system. "At Home in the World of Glass" - the validity of this statement is demonstrated by over 250 SORG designed furnaces in The result is the conversion of fuel to hot syngas - which means you'll need 20% to 30% less fuel to melt your glass, compared to oxy-fuel and air regenerative glass furnaces. The specific energy consumption for melting of a typical container glass could be approximately estimated in the range of 3.8 - 5.8 MJ/kg molten glass, depending on melting technology and process/product requirements. The recuperative furnace is mostly used in small and medium scale production plants and is popular in tableware glass. As melting energy accounts for about 60-70% of the total . Regenerative furnaces come in two types: Side-Port Furnaces.

Fouling and corrosion mechanisms, which are different in the top zone (1400-1000C) and bottom zone (1000-600C) of regenerator, are then examined separately. Low emissions. Most glass-container plants have either end-fired (burners at each end) or cross-fired (burners on each side) regenerative furnaces, and all flat glass furnaces are cross-fired with five or six ports on each side with two burners for each port. Preheat temperatures are normally in the range of 1300 - 1350 C, with higher values up to 1400 C, leading to very high thermal efficiencies.
