11 Industrial Combustion

Combustion has been the foundation of worldwide industrial development for the past 200 years [1]. Industry relies heavily on the combustion process as shown in Table 1.1. The major uses for combustion in industry are shown in Table 1.2. Hewitt et al. [2] have listed some of the common heating applications used in industry, as shown in Table 1.3. Typical industrial combustion applications can also be characterized by their temperature ranges, as shown in Fig. 1.1. As can be seen in Fig. 1.2, the demand for energy is expected to continue to increase rapidly. Most of the energy (88%) is produced by the combustion of fossil fuels like oil, natural gas, and coal. According to the U.S. Department of Energy, the demand in the industrial sector is projected to increase by 0.8% per year to the year 2020 [3].

As shown in Fig. 1.3, three elements are required to sustain combustion processes: fuel, oxidizer, and an ignition source usually in the form of heat. Industrial combustion is defined here as the rapid oxidation of hydrocarbon fuels to generate large quantities of energy for use in industrial heating and
