Method and burner for burning a mixture of fuel and primary air

摘要

In the method, which proceeds with the admission of secondary air from the environment, the supply of secondary air into the base region of the flame is restricted. For this purpose, use is made of a casing which at most feeds a small proportion of secondary air into the base region of the flame and supplies the main proportion of secondary air to the more remote flame region. As a result, the NOx emissions are minimised, while controlling the CO emissions.
