E-m-9/12 Low temperature burners - XPO™ burner
Product description
MAXON XPO™ burners are low temperature burners for use in liquid backed applications, including:
Water back heater
Fire tube boiler
Thermal oil heater
Direct contact water heater
Solution heating/tanks
Snow melters
XPO™ burners provide high efficiency operation with low excess air requirements. They are designed for ease of retrofitting into
existing liquid backed applications.
XPO™ burners are available in two basic versions:
Packaged (PB) with integral combustion air blower
External blower (EB) for use with an external combustion air source for extended capacities
Both packaged (PB) and external blower (EB) versions include two different choices for blast tube lengths. A 610 mm or 1220 mm
long blast tube is available. Blast tube length should be selected based on the wall penetration depth or non-liquid cooled portion of
fire tube.
The packaged (PB) version also includes a choice of blower voltage and a choice of air/fuel ratio control actuators. MAXON
requires the use of parallel positioning control systems. For indoor, general purpose installations, use Honeywell ControLink™ or
equivalent system. For outdoor or hazardous duty service installations, use MAXON SMARTLINK® MRV control systems.

Typical burner data
Fuel: natural gas at 15°C with 10.9 kWh/Nm3 HHV - sg = 0.6 [1]
Combustion air: 15°C - 21% O2 - 50% humidity - sg = 1.0 [1]
Stated pressures are indicative. Actual pressures are a function of air humidity, altitude, type of fuel and gas quality.

[1] sg (specific gravity) = relative density to air (density air = 1.293 kg/Nm3)
[2] Minimum burner capacity will be affected by fuel and applications parameters (heat flux).
[3] Turndown ratio will vary depending on the application heat flux. Lower heat flux (<3631 kW/m2) will result with lower turndown ratios.
[4] Capacity displayed assumes blower operation on 60Hz electrical supply. Gross output will be reduced by 17% if operated on 50Hz. Fuel and
air pressure should be reduced by 30% while motor power will reduce 40% with 50Hz operation. Turndown ratio will be reduced in kind with
minimum capacity remaining fixed.
