Zircoa Burner Block Zirconium Oxide Compositions Reduce NOx Emissions, Extend Burner Life and Improve Glass Quality

Calcia, Yttria or Magnesia stabilized burner blocks are engineered to withstand high temperatures and the contaminants present in fuel oil, while providing the added resistance to corrosion. There is a Zirconium Oxide composition that will satisfy your unique requirements and extend burner block life to more than one year. Markets served include: glass and quartz melting and high temperature sintering.
