Controlled system for a natural
gas/oxygen burner
ciency is achieved with pure oxygen since the waste
gas heat losses are minimised by the removal of the
79% of non-reactive nitrogen ballast that exists in air.
Furthermore, the less nitrogen, the less environmental
pollution through nitrous oxides (NOx).
A large number of lead works in Europe are already
benefiting from Messer’s know-how <strong>and</strong> industrial
gases for lead refining in order to maximise the efficiency
of the melting process with Oxijet® lance
systems or the tailor-made burners of the Oxipyr®
family (see table).

THE MAIN ADVANTAGES OF
USING OXYGEN ARE:
+ Greater flexibility due to higher melting efficiency
<strong>and</strong> shorter load times
+ Reduction in specific energy consumption
+ Decrease in amount of waste gas
+ Less environmental pollution from emissions
+ Less dust discharge due to lower flow rates
+ Lower investment costs due to smaller
filtration systems
+ No air preheating necessary
+ Integrated afterburning possible
