GAS APPLICATION
Oxyfuel Process
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
- The oxidising agent fed to the combustion process is enriched with oxygen, with the flow of oxygen being carefully regulated.
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.
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.
Oxipyr- IPC (internal post-combustion)
The combustion ratio of fuel and oxidising agent is selectively altered, with the oxygen flow regulated as a function of exhaust gas temperature and/or further process parameters. As a result, high-value fuels can be replaced by substitute fuels and the burden of post-combustion of pollutants in the exhaust gas, especially of the volatile organic components (VOC) can be relieved. Messer developed the Oxipyr-IPC process for this purpose. When using the Oxipyr-IPC process in rotary drum furnaces, oxygen and fuel requirements as well as the drum rotation speed are controlled automatically. Oxygen is always supplied via Oxipyr burners; with Oxijet oxygen lances used for certain types of furnace.
Advantages:
- Lower fuel consumption
- Reduces post-combustion burden
- Reduction in production costs
