Most reheating furnaces make use of direct flame burners having typically a rating from 500 to 3,000 kW. In search for a safe, flexible and clean burner for use in reheating furnaces, we have recently come across the ability to burn with all mix ratios of natural gas and hydrogen. The performances obtained even when operating with 100% hydrogen are remarkable, both in the flaming and flameless configurations. In all configurations, emissions are lower with 100% hydrogen than with 100% natural gas.

The new burner SMS ZeroFlame HY2 is able to burn with all mix ratios of natural gas and hydrogen.

This success is the result of an extensive development, prototyping and test campaign during the last two years. The new burner is a member of the SMS ZeroFlame product family and marketed under the name SMS ZeroFlame HY2. “We are always striving to contribute by researching innovative technologies to curb the emission caused by furnaces.” says Simone Zussino, Vice President of Competence Center Reheating Furnaces and Heat Treatment Lines with SMS group. “There are many good reasons for this. Our customers, who have to meet the requirements of increasingly stringent environmental regulations. The protection of the environment. And, of course, our innovative spirit that drives all of us here at SMS group.”

The new SMS ZeroFlame HY2 has been brought to the highest level of flexibility. In numbers

  • The burner can be operated with 100% natural gas as well as with 100% hydrogen – and all blends in between
  • Very contained emissions of Nitrogen Oxydes, as low as 40 ppm at 3% O2
  • The burner reaches up to 5% more emissivity compared to a traditional natural gas burner
  • Compared to a traditional natural gas burner, the SMS ZeroFlame HY2 offers substantial CO2 reduction
  • The burner is available in power sizes from 500 kW to 3,000 kW

Hydrogen is probably one of the best candidates for being the energy carrier of the near future. It will facilitate the transition from the age of fossil fuels to the carbon-free age – that much is certain. Those who want to gear their production for the future and remain competitive will invest now in lower-emission production. There is no time like the present.
