Abstract
In the production of carbon black, low BTU content gases are combusted in a compact combustion zone with near stoichiometric amounts of oxidant gases, tempered to the desired temperature and volume with a diluent gas stream which can be selected from air and filter off-gases, and introduced into a reactor for the pyrolysis of a carbonceous feedstock to form carbon black.
