摘要：	"It is the first on the market. None of our competitors have it," said Marzio Ferrini from Ammann and he added, "the hydrogen burner is available today." The new burner delivers precise control of the flame shape and an optimised air/fuel mix to increase combustion efficiency. It has redesigned electronics and mechanical components to ensure ease of maintenance. Using a fuel supply of 100% hydrogen, the burner operates cleanly. The system is available as a retrofit and can also be used to burn a combination of hydrogen and natural gas to meet available supplies. The company says that its existing asphalt plant gas burners meanwhile can use a combination of 28% hydrogen mixed with natural gas without any need for special changes. If Ammann carries out some modifications, the firm's conventional burners can use a combination of up to 60% hydrogen and 40% natural gas. Hydrogen is the world's most common element and is non-toxic. "After combustion we have only water vapour," Ferrini said. The new hydrogen burner is said to be easy to maintain and has been developed with a view to the future. Industrial operations are being taxed for CO2 emissions in Europe and this is coming for China also, with similar moves likely elsewhere in the world in due course.
