2. YETEN provides complete solutions for the needs of industry about combustion and heating processes since Since then, it focused and gained much experiences on highly efficient, low emission and robust design burner systems for industrial furnaces.
YETEN company uses computational tools in reseach&development and in design. These tools are CFD (computational fluid dynamics ) softwares and 2D, 3D CAD systems.
The burner improvement and performance tests have been made in our own test furnace in R&D department.
YETEN is ISO 9001:2000 quality management system certified company. We offer research, development, desing, installation and other services under ISO 9001 guarantee. NFPA, EN safety standards are also adapted in our projects.
Yeten exports its burners all around the world especially industrialized countries. The leading manufacturers of the related sectors inland are also our references.

OE OXYGEN ENRICHED BURNER
Description:
Unfortunately, much more improvements
in industry are resulted in reduction of fuel
sources and environmental pollution. To
prevent these negative conditions, some
different methods are used. One of these
methods is to use oxygen enrichment in
combustion systems.
Mildflame® Oxygen Enriched Burner’s design is based on flameless combustion technology. Gas and air are mixed in the burner block to supply pre – firing below 850 °C. Above 850 °C furnace temperature , flameless operation is achieved by means of air flow manipulation using the switch valve at air inlet and continues to burn with oxygen supplementation.Air nozzle velocity increases in flameless combustion mode and the flame temperature decreases due to the recirculation of combustion products into the reaction zone.

BENEFITS :
REDUCTION IN SCALE LOSS
In iron & steel industry , oxide formation (scale) composed during the hot working causes serious material losses.Making the combustion process with low air excess ratio , can reduce the scale formation.Reduction of oxygen from 2.2 % to 1,1 % and reduction of scale formation from 1 % to 0,7 % cause 2.4 % fuel saving.
