General Product Information

Extended stable combustion and lower emissions

As part of our ongoing commitment to meet the changing requirements of your operating assets, Siemens offers the latest technology to help you enhance your operating plant reliability and performance. One of our modernization offerings is the HR3 Burner Retrofit.

The HR3 Burner Retrofit design enhances the mixing of natural gas fuel and combustion air during the gas premix mode. The design also reduces turbulence of the combustion airflow while increasing its velocity through the combustor. Together, these features contribute to more stable combustion and can help lower NOx emissions.

The implementation of the HR3 Burner provides significant performance advantages and offers attractive financial payback options.
