Intended service and typical application
Application details
®
OXY-THERM
FHR burners can be used in furnaces and melters, steel reheat furnaces, linear hearth furnaces, rotary hearth
furnaces, reverberatory furnaces, and other high temperature applications.
®
OXY-THERM
FHR burners have a unique design which allows fuel interchangeability and easy maintenance. They are able to
operate on fuel gas, light fuel oils or heavy fuel oils. Each fuel requires the use of separate nozzle inserts. Following plant safety
procedures, the burner fuel inserts can be removed while the furnace is still in operation. In some cases, fuel oils may be atomized
by fuel gases allowing simultaneous firing of two fuels.
®
OXY-THERM
FHR fuel inserts are custom designed for specific flame sizes and capacities. Contact MAXON with information on
your furnace dimensions, process, and capacity requirements.
.
WARNING: Consult the installation and operation manual for safe removal of burner inserts. Use caution
as hot furnace gases will be present around typical burner installations.
Fuels
®
OXY-THERM
FHR burners are designed for firing on any clean fuel gas or light and heavy fuel oils.
Process flows and oxygen content
®
OXY-THERM
FHR burner requires no additional oxygen for complete, clean combustion beyond the oxygen fed through the
burner oxygen connection.
Process temperatures
®
OXY-THERM
FHR burners may be applied to furnace temperatures up to 3050°F with standard block materials. For higher
temperatures, please contact MAXON regarding special block materials.
Cooling flow, either clean, dry air or oxygen, must be used whenever the burner assembly is in a high temperature atmosphere and
is not firing. See installation and operating instructions for more details.
Staged oxygen control valve must be placed in position #11 as shown on page 3-18.4-8 to provide optimal
cooling to the burner.
Burner blocks
MFZ-6 Mullite burner blocks are used with gas firing and oil firing. Burner blocks are available in standard lengths. See
"Dimensions and weights" on pages 3-18.4-10 and 11.
