6.1 INTRODUCTION

The specifi c emphasis of high temperature air combustion so far has been on different

kinds of furnaces and boilers for industrial applications. In all cases significant
impact was achieved from the point of view of significant energy savings (up to
about 60%), reduced pollutants to the environment including CO

(compact size) of the equipment. It is also clear that we have begun to think about
the traditional definition of flame as one that gives heat and light. Indeed, for the
high temperature air combustion case one can have a flame without visually observ-
ing it since the flame can be colorless. For much of the 20th century the technological
advances on the combustion of fuels have not been at the level of those in the
electronics industry; see Table 6.1 .
This chapter provides our vision of the application of high temperature air
combustion technology to other systems. High temperature air combustion technol-
ogy, in principle, can be utilized in almost all kinds of combustion, power, and
propulsion systems,

discussed in Chapters 1 through 5. Some development projects are already in
progress to apply the HiTAC technology principles for use in coal burning boilers,
heavy fuel oils, waste fuels and chemicals, and solid wastes. Some of the current
development efforts using high temperature air combustion technology are given in
Table 6.2 .

in addition to its demonstrated use in industrial furnaces,

those already developed and currently being developed, are given in Figure 6.1 . The
near-term future developments and applications of this technology are summarized
