sg (specific gravity) = relative density to air (density air = 0.0763 lb/ft³(st)).
Combustion air and gas differential pressure are measured between burner test connections and combustion chamber pressure.
Excess air based on min. capacity required for ignition. Increased smoke numbers possible, depending on air temperature and fuel-oil quality
When gas firing on series C burners, a ½” diameter by-pass line is necessary to keep atomizing air passage purged. When oil firing, the use
of a flame rod for flame detection is not possible. Atomizing air should be fresh and not preheated, indicated air pressures and flows should
always be available over the entire capacity range.
[5] Pilot gas must be regulated separately to 3”wc-4”wc at pilot inlet. For light off with full excess air however, pilot must be increased to the indicated main burner minimum capacity, requiring considerably higher gas pressures.
[6] Flame lengths measured from the end of the burner block at maximum rated capacity.
Overfiring or excess fuel operation requires higher natural gas supply pressures and gives longer flame lengths

High temperature burners - KINEMAX®
Selection criteria
KINEMAX® burner versions
The KINEMAX® burner is available in two basic versions. KINEMAX® type G burners are designed to operate on gas only.
KINEMAX® type C burners are able to operate on both gas and light oil (not simultaneously). Each type has different sizes
available to cover a broad range of capacities to suit all heating applications.
All burners are available in ANSI and ISO version. Connections larger than 2” are available as threaded or flanged. (see detailed
drawings on page …)
Burner discharge sleeves are available in different lengths and materials:
„ standard version with refractory block for installation in refractory walls, available in different lengths
„ complete with block sleeve to provide additional block support in chamber walls of softwall constructions. Block sleeves are
available in stainless or carbon steel.
„ complete with stainless steel discharge sleeve offering lightweight refractory-less burner for use in air heating applications.
Maximum upstream temperature is 1000° F and maximum downstream temperature for this configuration is 1500° F
„ Optional mounting flange enables easy mounting in cases where the standard or extended block lenghts do not comply with
installation insulation thickness.

Application details
In high temperature furnaces KINEMAX® burners can be used wherever good temperature uniformity without flame impingement
is required. Among the typical applications are oxidizers, forge furnaces, annealing furnaces, melting furnaces, lehrs, kilns,
ceramic furnaces, etc. They can also be used in certain air heating applications.
Special considerations have to be taken to protect the flame from high cross velocities. Contact MAXON for more details.
Maximum capacities
All KINEMAX® burners can be fired on-ratio, excess gas (40%) or with excess air (depending on size, up to 4700 %). Performance
data are given on page 3-11.4-10.
Maximum capacity is a function of differential air pressure supplied to the burner air inlet as read between air test connection and
combustion chamber. Combustion air blower rating must be sized to allow for manifold pressure losses
Preheated air
Preheated combustion air up to 800° F can be accommodated by standard KINEMAX® burner, resulting in lower fuel
consumptions.
The preheated combustion air can have reduced oxygen levels (as low as 17 % O2 if combustion air is 425° C)
Mixing of some low O2 flue gas allows to combine system thermal efficiency with best emissions.
Process temperature
Standard refractory block permits operation at combustion chamber temperatures of 2600° F. Special refractory block material
allows operation up to 3000° F.

High temperature burners - KINEMAX®
The optional stainless steel sleeve (without block) can only be used when secondary cooling air (t° < 575° F) is available and can
be forced over the combustion sleeve.
Piloting and ignition
KINEMAX® burners are equipped with an integrated raw gas pilot, but can use direct ignition as well. Recommended 3/8” pilot gas
fine adjustment needle valve is available as an option. Pilots shall be used only for ignition of the main flame (interrupted pilot).
Permanent pilot operation is not advised (no permanent or intermittent pilot). Use the main burner at minimum capacity for
continuous operation.
Use minimally 5000 V/200 VA ignition transformers for sparking of the spark igniter.
Locate pilot gas valves as close as possible to the pilot burner gas inlet, to have fast ignition af the pilot burner.
Typical ignition sequences
„
„
„
„
„
„
„
„
„
„
Pre purge of burner and installation, according to the applicable codes and the installation’s requirements.
Combustion air control valve shall be in the minimum position to allow minimum combustion air flow to the burner.
In case of oil firing: Atomizing air should be applied to the burner.
Pre-ignition (typically 2s sparking in air).
Open pilot gas and continue to spark the igniter (typically 5s).
Stop sparking, continue to power the pilot gas valves and start flame check.
Trip burner if no flame can be detected from here on ?
Check pilot flame stability (typical 5s to prove the stable pilot).
Open main gas or oil valves and allow enough time to have main gas or oil in the burner. (typical 5s + time required to have
main gas or oil in the burner).
Close the pilot gas valves.
Release to modulation (allow modulation of the burner).
Above sequences shall be completed to include all required safety checks during the start-up of the burner (process & burner
safeties).
Ratio control
KINEMAX® burners can be fired on ratio throughout the firing range or set to give a choice between on ratio and excess air or
excess fuel firing. As high as 4700% excess air is possible at minimum capacity.
Air / fuel ratio control can be accomplished with MAXON MICRO-RATIO® valves and SMARTLINK® technology.
Flame supervision
All KINEMAX® burner sizes and types can be supervised by means of a UV-scanner.
Burner design incorporates UV-scanner port suitable for supervision of both pilot and main flames.
Two scanner positions are available (see drawings on pages…)
Pay attention to possible pick-up of strange flames (if any in the furnace) when using UV-scanner for flame detection. Allow some
purge or cooling air to the scanner connections (typically 2 m³(st)/h of fresh clean air)
Scanners should be installed as close to the burner as possible.
Sizes 1-1/2 up to 4 have a flame rod assembly optional available. Flame rod sensing should not be used on oil firing.
Flame development
KINEMAX® burners shall be installed in combustion chambers or furnaces that allow full development of the burner flame.
Cylindrical combustion chambers or flame protection sleeves shall be sized correctly.
Consult MAXON for proper combustion chamber lay-out.

E - i - 1/08
Combustion air and gas piping
Combustion air piping to the burner shall be done in such way that the air flow to the burner will not disturb the flame. For optimum
performance, the first elbow in combustion air piping must be at least six pipe diameters from burner test connection. Location of
air control valves directly on the burner inlet is not advised. When possible, locate the air/gas/oil control valves in a position that
allows viewing of burner flame during adjustment. Protect control valve operator from excessive radiant and/or ambient heat.
When using one air/gas control valve for multiple KINEMAX® G burners, gas check valves should be installed as close as possible
to each burner inlet for dependable light off. MAXON air and gas balancing valves may be used on multi-burner installations for
improving heating uniformity.
Oxygen enriched combustion air
MAXON KINEMAX® burners can be used with oxygen enriched combustion air.
Consult MAXON for more information.
