18.1 Introduction
As discussed in Chapter 1, there are many ways that
oxygen can be used to enhance combustion processes,
some of which do not involve traditional burners. For
example, oxygen can be lanced into the ame with a
separate injector, which does not adversely affect the
existing air/fuel burner. This chapter is focused on
burners specically designed to use oxygen for com-
bustion. The most traditional type of burner using
oxygen for combustion is usually referred to as an oxy/

for decades, although today’s burners are sig
