MEGAFIRE® Gas/Oil Burners

Performance and Selection Data

Packaged Internal Construction Basic MEGAFIRE® Burners include an air controlshutter, fuel nozzles, mixing cone, pilot and provisionfor UV scanner in one compact package.

Combustion air is provided by either an integralcentaxial (IB) in-line blower or via an (EB) externalblower. A differential air pressure (see page 2604)must be provided for cataloged capacities. IB versionis used for negative to balanced combustion chamberpressures. For back pressure or over-fire applications,use EB version and external blower.

Flame discharge is through a stainless steelcombustion sleeve (1100°F (593°C) maximumchamber temperature) or a refractory block (1600°F(870°C) maximum chamber temperature) completewith seal and support housing.

Piloting is by an independent, spark-ignited, rawgas pilot.

Burner mounting uses an integral mountingflange, but additional support MUST be provided.

Combustion air control is accomplished with abuilt-in air shutter, connected via control cable, to afuel control valve (Maxon MICRO-RATIO® Valve). The“XC” version utilizing external control of air and fuel isalso available.

Suitable fuels include natural gas, propane, or #2oil at 50 SSU viscosity or less. Atomizing steam or airis required at 60 PSIG for oil firing. Simultaneous gasand oil firing is possible, up to the total rated capacityof a MEGAFIRE® Burner.

A complete system utilizing MEGAFIRE® Burnersalso includes gas, oil, and atomizing media pipe trainsand a control panel.

“EB” External Blower version

“IB” In-Line Blower version

Optional Block/Seal &Support Assembly

End View IntoFace of Burner

To select your MEGAFIRE® Burner, specify:

1. Quantity2. Size

– 15M = 15,000,000 Btu/hr (maximum)– 30M = 30,000,000 Btu/hr (maximum)– 45M = 45,000,000 Btu/hr (maximum)

3. Fuel and atomizing media– Gas: If other than natural or propane gas,

provide:Specific fuel and/or analysis;Specific gravity, calorific value, andavailable pressure

– Oil: If other than #2 oil, provide:Specific fluid and/or analysis;Specific gravity, calorific value, viscosity,temperature and available pressure

– Atomizing media:Air – Volume and pressureSteam – Volume, temperature andpressure

4. Combustion chamber static pressurecondition

5. In-Line (IB) or External (EB) Blower version– For “IB” version:

– Electrical specification for motor– For “EB” version:

– Electrical specification for motor– Blower discharge position– Blower volume and pressure

– For “XC” version (EB only):– Verify that control of combustion air/fuel gas

and/or fuel oil is specified6. Discharge options

– #310 stainless steel discharge sleeve, or– Refractory block with seal and support housing

7. Control valve options– Standard cam version– Packaged control valve arrangement:

Right-hand assembly, orLeft-hand assembly

8. Assembly arrangement options– Gas inlet position (Note: pilot/scanner always

opposite side from gas inlet)– Air inlet position

9. Accessory options– Connecting base & linkage for specific

automatic control motor– Atomizing air train– Atomizing steam train– Light oil train– Gas train– Shut-off valve(s)– Control panel
