For additional construction information refer to Dimensions & Parts List 4422-2.
Used in furnace construction where there is no steel shell, only refractory. Identical to standard burners except no mounting flange. For dimension information refer to Dimensions & Parts List 4422-4. Only available with the standard burner or double boss option. FIBER WALL MOUNTING (4422- -Z)
OTHER EQUIPMENT OPTIONS For application of burners to chamber temperature over 2000 °F (1093 °C), see Bulletin 4425. For 4422/25 burners with slotted discharge tiles that produce a fishtail shape flame, consult with Fives North American Com- bustion, Inc. for ordering information. For application of 4422/25 burners to high combustion cham- ber pressures (up to 15 psi (1 bar), contact your Fives North American Combustion, Inc. office. For use with preheated combustion air systems, refer to Bulletin 4825 (up to 1200 °F (648 °C) air). For burners with larger heating capacity, refer to Bulletin 4545 or 4514 or consult your Fives North American Combustion Inc. field office.
Z
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 2.00" (59 mm) of its length, it is particularly suitable 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 (982 °C) from reaching the metal. Specify the mounting flange "Z" dimension between 2.00" (59 mm) and 9.00" (229 mm) to the nearest 0.5" (13 mm) 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 9.00" (229 mm) long square tiles are also available with support jackets for applications such as air heaters where frequently the tile is not supported by refracto- ry. They also can be mounted in furnaces when desired. Jackets are available in three different 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.
