Hydrogen is the fuel gas with the highest burning rate and flame temperature and was already a fuel used for energy by industry before the power to fuel trend. Often as a by-product from chlorine gas production or conventional H2 steam reformers, where it is "contaminated" with other hydrocarbons, it is used to heat convection reformers. CS has been supplying burner systems for various concentrations of H2 for all types of hydrogen production plants for over 10 years. Hydrogen has also always been an important fuel for the alternative combustion of steam boilers.
Not only the CS burner systems installed in the SWP series, but also the equipment and safety features of the burner systems are specially designed and approved for hydrogen. Specific high-temperature materials and design of the gas nozzles ensure the same long service life compared to natural gas firing systems. In order to meet the legal emission requirements, the combustion air is supplied by the SWP burner in 2 layers. In addition, other NOx-reducing measures (flue gas circulation, sub-stoichiometric combustion or steam injection for H2 combustion) can be combined.
NH3 or ammonia is, besides H2, the only synthetic fuel within reach without CO2 emissions. NH3 is much easier to store and transport than H2 and will therefore play a significant role in the power to fuel transformation. For ammonia combustion, CS has developed a highly efficient LowNOx concept that takes into account all available NOx reduction options and ensures reduction rates of up to 90%. CS has applied for the corresponding patents.
