Abstract
One of the most important requisites concerning the FS process is the equipment. All fundamental principles are based on the flame configuration, atomization device, flame temperature, powder collection system, and burner. The wide range of apparatus configurations contribute to the several materials that have been produced by the technique described in this book. As it has a strong influence in the final properties of the product, the description of the different equipments reported in the literature is an important feature. Most of the devices reported in this chapter were built in laboratory facilities, but several companies such as DuPont, Cabot, Degussa, Kemira, Tioxide, Corning Glass, and General Electric have been using their own equipments. The flame spray (FS) equipment can be basically divided in three sub-components: the atomization device, the group of flames, and finally the powder collection system. Each of these devices has its importance in the process of producing powders using the FS method, and all of them have different designs and different sub-components, according to the industry or institution that developed/fabricated the equipment. Thus, in this chapter, the main features of the FS apparatus are discussed, and a special attention was given to the flame device, which is the most important device of the equipment.
