TRX Flameless Roof Burners
Flameless Radiant Roof Burners represent the latest generation of radiant roof burners. Their operation is based on flameless combustion, that is able to provide very low NOx emission levels.
Overview
TRX burners represent the most advanced solution in terms of radiant burners, since they can operate both in flame and flameless modes.
Thanks to coupled gas and air staging, NOx emissions are brought down to 70 mg/Nm3. As traditional roof burners, they guarantee a high efficiency heat exchange between furnace and charge. Furthermore, in order to uniformly distribute the waste gas, two different types of TRX burners are installed: one with the flame rotating in a clockwise direction and the other in a counter-clockwise direction.
Technical Data
Main technical features:
- Very low NOx emissions
- Very low CO emissions (below 5 ppm)
- Maximum fuel efficiency: low excess air operations
- Extended turn down in flameless mode
Fuels: Natural Gas, COG, LPG (and hydrogen mixtures of them).
Turn down: 10%-100%.
Innovation
Special flame design required to achieve a highly uniform heat distribution and intense heat flux with a high turbulence intensity.
Special flameless design to bring down NOx emissions.

Environment
70 mg/Nm3 @ 3% O2 for Natural Gas
100 mg/Nm3 @ 3% O2 for COG (*)
The emissions are referred to these operating conditions:
- Air excess 5% (N.G.), 7% (COG)
- Air temperature less than or equal to 450°C
- Furnace temperature less than or equal to 1250°C
- Burner load á 80%
The reported value is the expected one. The guaranteed value will be fixed case –by- case according to furnace type and working conditions.
(*) The emission values are subject to variation according to specific fuel analysis (fuel NOx).
