Burners for oxy combustion - SolMet

SOL designs, manufactures and offers its customers different kinds of burners for oxy combustion, ranging from a few hundred kilowatts to more than 3 MW, specifically designed for different sectors and adaptable to different melting plants and diverse process and application needs and requirements. These are sold under the SOLMET trademark and can operate using different kinds of fuel (methane, GPL, oil…).

For the production of cast-iron in rotary kilns, SOL produces burners with water-cooled sleeves, fitted with specific nozzles specially designed to produce suitable flame fluid dynamics and the fast, uniform heating of the content of each rotary kiln. They can also be used to preheat ladles, and offer clear, proven benefits in terms of shorter heating times and fewer defects in the castings, thanks to the greater fluidity of the molten metal.

For the aluminium sector, specific burners for fixed- or tilting-axis rotary kilns with single or double passage are available: these can work in difficult conditions such as processes and salt, re-melting of process waste, the melting of contaminated and low-quality scrap.

For reverberatory melting furnaces with single or double chambers, products include burners that can be installed in the vault, on the wall or in special fume-recycling ducts that help guarantee high productivity while limiting fuel consumption and losses through oxidation. Special burners make it possible to use a dynamic flame that ensures high thermal efficiency and effectively reduces the formation of local overheating, which tends to produce slag and reduce productivity.

Among the principal models available for wall installation, usable also in the glass sector, “flat” flame burners can produce a broad flame that heats the surface of the bath energetically but uniformly.

For forges and rolling mills, regenerating and self-recuperating SOLmet burners can operate in oxy combustion or in oxygen enrichment only, guaranteeing rapid, uniform heating and significant fuel savings.

Numerical and thermo fluid dynamic (CFD) modelling carried out jointly with the principal research centres and universities is used to verify the applications proposed during the design phase.
