This patented combustion technique, can be applied to conventional end and cross fired regenerative glass furnaces, to reduce NOx to a level below that proposed in EU limits and at the same time reduce CO2 emissions.
The auxiliary combustion firing technique, combined with conventional firing is capable of reducing NOx without loss of production, glass quality, efficiency or damage to the furnace.
The location and operating conditions for this system are critical, and must be optimised with the conventional firing conditions. Modelling of the furnace, both as Computerised Fluid Dynamics (CFD), and physical modelling are both used to determine these factors for any particular furnace.
The Process can be applied to existing furnaces with, at the most, only minor alterations. Global Combustion Systems provide full supervision, commissioning, and maintenance services with this system. Global Combustion Systems also provide auxiliary equipment including complete fuel control systems.
