REGEN Burners


REGEN Burners are a range of Low Nox Regenerative burners developed by ENCON in association with Swiss Melting Technologies S.A.

REGEN burners increases the thermal efficiency of the process by increasing the efficiency of heat recovery from flue gases, With REGEN series we can attain a preheat temperature of 200 to 300°C less than the process temperature.

We were judged as "WINNER for Innovation challenge 2019 for Waste Heat Recovery" by FLCTD https://www.low-carbon-innovation.org/whr-winners-2019

The burner can be used with various Gaseous & Liquid fuels like

GASEOUS FUELS : LPG, Natural Gas, Producer/ Syn Gas, Coke Oven Gas, Blast Furnace Gas, etc
LIQUID FUEL : Diesel, LDO, HFO, FO, pyrolysis oil, etc

We also offer Multiple fuel option in the same burner.

CONTACT US AT info@encon.co.in for live demonstration of the burners at our works.


BURNER Design : Each regenerative burner consists of the following main parts

  • 1. Burner with Nozzles and burner Block
  • 2. Regenerator box with Media Balls
  • 3. LPG/NG Pilot burner with UV sensor and Ignition Transformer

We have designed the burners for two modes of operations, Low NOx Flameless operation and a normal flame operation, FLAMELESS mode of application can be selected for process temperatures higher than 800 °C. The NOx emissions ca reduce between 20 to 80% depending on the process temperature and parameters between the Normal and Low NOx flameless mode, For more information PLEASE CONSULT US at info@encon.co.in

WORKING OF REGEN BURNERS

In Mode A, Burner A fires and Burner B act as a regenerator or heat sink, the flue gas is sucked by Burner B, the flue gas travels through the media box of Burner B to the chimney, The Media box is filled with Ceramic balls which absorbs up to 85% of the heat of the flue gasses.
In Mode B, the process is reversed and Burner A act as the regenerator and Burner B fires, In this case combustion air passes through the hot media and we are able to achieve a Combustion air temperature which is approximately 200 to 300°C below the process temperature depending on the process parameters, for example if the process temperature is 1200 °C we will be able to achieve a temperature of 900 to 1000 °C for the combustion air.

We invite people to visit our facility to see a live demonstration of the burners. The facility has all the latest Instrumentation and controls, and numerous woking parameters of the furnace and the Flue Gas are captured on a PLC. PLEASE CONTACT US at info@encon.co.in, if you would like to visit the facility or want more information about it. Some pictures of the test facility
