OTHER EQUIPMENT OPTIONS For application of burners to chamber temperature over 2000°F, see Bulletin 4425. For 4422/25 burners with slotted discharge tiles that produce a fishtail shape flame, see Sheet 4425-2. For application of 4422/25 burners to high combustion chamber pressures (up to 15 psi), contact your Fives North American Combustion, Inc. office. For use with preheated combustion air systems, refer to Bulletins 4824 (up to 1000°F air) and 4825 (up to 1200°F air). For burners with larger heating capacity, refer to Bulletin 4545 or 4514 or consult your North American field office.
This construction can be used to locate the tile face flush with your furnace wall. Because the round tile is encased in RA330 expanded metal for all but 2" of its length, it is particularly suit- able for fiber-lined furnaces or other applications where the tile is not supported and contained. The tile should be insulated to prevent temperature over 1800 F from reaching the metal. Specify the mounting flange "Z" dimension between 2" and 9" to the nearest 0.5" to locate the tile face flush with your inside furnace wall. For dimension information refer to Dimensions & Parts List 4422-7. TILE SUPPORT JACKETS (4422- -LC, 4422- -L4, 4422- -L9) 4422 Burners with the standard 9" long square tiles are also available with support jackets for applications such as air heaters where frequently the tile is not supported by refractory. They also can be mounted in furnaces when desired. Jackets are available in three differ++ent metals and maximum temperature ratings. They must be protected with sufficient insulation so as not to exceed rated temperature. Maximum temperature rating for jacket metals depends upon frequency of heat-up/cool-down cycles. As an example, batch annealing furnaces that are heated and cooled every day should use the "intermittent exposure" ratings. Burners in a continuous annealing furnace that remain at the same temperature for months at a time, can use the higher "continuous" rating.
For firing oil and/or gas (dual fuel) refer to Bulletins 5422 and 6422/25.
