Chamber Furnace
Process Description
Hearth furnaces are mainly used as melting units, but also as holding and homogenising furnaces before casting. Depending on the application they can be round or rectangular, tiltable or stationary. The required energy input is by means of burner systems such as Oxyfuel.
In the Oxyfuel process, the combustion processes are carried out by means of an oxygen burner (Oxyfuel burner) which is operated with pure oxygen or oxygen-enriched air as an oxidising agent. Messer has developed the family of Oxipyr burners for this purpose.
In comparison to burners which use air as an oxidant, Oxipyr burners provide a range of process technology advantages:
- Higher combustion efficiency
- Higher melting rate
- 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
Gas Application
Combustion with oxygen (Oxyfuel) instead of with air as an oxidising agent, reduces fuel consumption and increases process efficiency.
Messer Solution
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.
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.
