Oxyfuel-process for block pre-heating 
Addition of inert gas during DESU process
In the oxyfuel process, the combustion processes are carried out by means of an oxygen burner (oxy-fuel burner), which is operated with pure oxygen or with oxygen-enriched air as oxidant. Messer has developed the Oxipyr burner family for this purpose. Compared to burners that use air as an oxidant, oxy-fuel burners have a number of process technology advantages:



Higher combustion efficiency
Higher melting performance
Faster heating-up times
Lower fuel consumption
Higher processing temperatures possible
Faster reaction speeds
Lower exhaust gas levels
Less dust
Lower emissions
Lower production costs


In addition to the gases required for your process, Messer offers a variety of equipment for its optimisation under the brand names Oxipyr and Oxijet. 

In order to select the optimum system, experts from Messer first carry out a comprehensive process analysis. Following calculations and basic engineering, suggestions are made for optimisation and further procedures.

Oxipyr – Burner Technology

The characteristics of the burner types are multi-faceted and range from low to high momentum burners, oxyfuel to oxygen/air mixing burners and burners for different fuels or fuel combinations. The systems are controlled manually, semi- or fully automatically following compositions or temperature.
