ABSTRACT

Most industrial heating processes require substantial amounts of energy, which is commonly generated by combusting hydrocarbon fuels such as natural gas or oil. Most combustion processes use air as the oxidant. In many cases, these processes can be enhanced by using an oxidant that contains a higher proportion of O2 than that in air. This is known as oxygen-enhanced combustion or OEC. Air consists of approximately 21% O2 and 79% N2, by volume. One example of OEC is using an oxidant consisting of air, blended with pure O2. Another example is using high-purity O2 as the oxidant, instead of air. This is usually referred to as oxy/fuel combustion.
