Linde to Supply New Flameless Oxyfuel Preheating System to Stainless ...

Tag : converter steel
The Linde Group today announced its agreement with international stainless steelproducer Outokumpu for a new flameless oxyfuel preheating systemfor its ferrochrome converter in Tornio, Finland.
The self-cooled flameless oxyfuel system will replace the existingconventional water-cooled oxyfuel system, providing Outokumpu withmore economical and environmentally friendly production. The new2.5 MW flameless oxyfuel system for drying and preheating of theferrochrome converter will be commissioned in September 2008.
This will be Finland’s first flameless oxyfuel systeminstallation and will provide Outokumpu’s Tornio Works withreduced heating cycles, greater energy efficiency and up to 50%lower fuel consumption and CO2 emissions.
“Flameless oxyfuel delivers a simple, compact and low weightinstallation as compared to an air fuel system with a recuperatoror regenerative solution. It is seen as the best availabletechnology for heating and not only allows for ultra low NOxemissions, but brings extended refractory life through more uniformtemperature distribution” said Joachim von Schéele,Marketing Manager, Metals and Glass Industries, Linde GasesDivision.
“It is Outokumpu’s policy to follow and implementtechnology that decreases fuel consumption and CO2 andNOx-emissions. Linde’s flameless oxyfuel system is acompelling technology that fulfils this need. Outokumpu is nowinvesting in the flameless oxyfuel system and will continue toutilise technologies that increase output while saving energy andreducing emissions,” said Mr Mauri Kauppi, Steel Melting Shopand Hot Rolling Mill Manager, Outokumpu.
Linde has installed 30 flameless oxyfuel systems over the past fiveyears, primarily in reheat and annealing furnaces, some using lowcalorific fuels. For drying and preheating of ladles andconverters, flameless oxyfuel has already been successfully used atfive other major steel works.
