FETURES & BENEFITS Low temperature burner for use with clean fuel gases Single digit NOx emissions at 30% excess air High efficiency with low excess air requirements Capacities up to 30 kw with a least 3: turndown ratio For use in indirect fired solution backed heaters PRODUCT DESCRIPTION Maxon XPO burners are low temperature burners for use in liquid backed applications. They provide high efficiency operation with low excess air requirements and 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. 60 mm or 0 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. MXON 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 MXON SMRTLINK MRV control systems.

SELECTION CRITERI pplication details XPO burners can be used in all indirect fire tube liquid backed solution heater applications. They combine flexibility and stability with low NOx emissions. PROCESS TEMPERTURE The XPO burner is engineered for installation in moderate temperature (less than 870 C), liquid backed fire tubes. Protect the burner from high temperatures during a burner stop (purge to avoid back flow of hot process air). PILOTING ND IGNITION ll XPO burners are equipped with an independent pilot design. Pilots shall be used only for ignition of the main flame (interrupted). Use of a standing (continuous) pilot is not recommended. Use minimally 000 V/00 V ignition transformers for sparking of the spark ignitor. Start the burner at low fire setting only. Direct spark ignition of standard XPO burners is possible. Locate one pilot gas valve as close as possible to the pilot burner gas inlet to have fast ignition of the pilot burner. TYPICL IGNITION SEQUENCE 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. Pre-ignition (typically seconds sparking in air). Open pilot gas and continue to spark the ignitor (typically seconds). Stop sparking, continue to power the pilot gas valves and start flame check. Trip burner if no flame from here on. Check pilot flame stability (typically seconds to prove stable pilot). Open main gas valves and allow enough time to have main gas in the burner (typically seconds + time required to have main gas in the burner). Close the pilot gas valves. Release to modulation (allow modulation of the burner). bove sequence shall be completed to include all required safety checks during the start-up of the burner (process and burner safeties). RTIO CONTROL ccurate air/fuel ratio control can be accomplished with MXON SMRTLINK or Honeywell ControLink actuators. Precise ratio control will yield optimal emissions and efficiency performance. FLME SUPERVISION XPO burner flames shall be supervised by the use of a UV or IR scanner. PIPING Follow all applicable codes including regional codes, local directives, standards and recommendations of your insurance carrier when designing and installing XPO burners. Installation should only be undertaken by qualified gas contractors licensed for any regional or local requirements. Piping weight should be independently supported. Do not use the burner as a piping support or hang weight from the burner s flange connections. FUELS XPO burners are designed for firing of clean fuel gases such as natural gas or LPG. 3M-00E 7

EXPECTED EMISSIONS The XPO burner will achieve ultra low NOx emissions while operating at 30% excess air level. The burner provides higher combustion efficiency and lower emissions without the use of expensive FGR or exotic/fragile materials. Exact emissions performance may vary in your application. Contact MXON for information on installation-specific estimates and guaranteed values. No guarantee of emissions is intended or implied without specific, written guarantee from MXON. Fire tube sizing See the table below for ideal fire tube size. The burner should be sized within the range of the suggested heat flux. For best emission performance, the burner should be fired into a fire tube with the lowest suggested heat flux.

STRT-UP INSTRUCTIONS FOR XPO BURNERS Instructions provided by the company or individual responsible for the manufacture and/or overall installation of a complete system incorporating MXON burners take precedence over the installation and operating instructions provided by MXON. If any of the instructions provided by MXON are in conflict with local codes or regulations, please contact MXON before initial start-up of equipment. Read the combustion system manual carefully before initiating the start-up and adjustment procedure. Verify that all of the equipment associated with and necessary to the safe operation of the burner system has been installed correctly, that all pre-commissioning checks have been carried out successfully and that all safety-related aspects of the installation are properly addressed. Initial adjustment and light-off should be undertaken only by a trained commissioning engineer. Do not operate the burner without the burner cover and observation window securely attached and sealed to the burner air housing. CHECKS DURING ND FTER STRT-UP During and after start-up, check the integrity of the system. Check all bolted connections after first firing (first time on temperature) and retighten if necessary. PILOT IGNITION Before ignition of the pilot, adjust the combustion air to the minimum burner air flow. Pilot will not ignite if too high an air flow exists. Set pilot gas flow to the correct value before pilot ignition attempt. MIN BURNER IGNITION Set correct gas flow for burner minimum capacity before attempt of main burner ignition. fter ignition of main burner, allow some time on minimum capacity to allow the burner parts to heat up slowly. DJUST IR/GS RTIO, SET MXIMUM CPCITY Once the main flame is ignited, adjust air/gas ratio of the burner to have the required combustion quality and slowly increase capacity. Do not increase capacity too fast to avoid damage to burner parts or furnace due to excessive temperature gradient. Stack O should be used to do final set-up of air/fuel ratio. MINTENNCE ND INSPECTION INSTRUCTIONS SFETY REQUIREMENTS Regular inspection, testing and recalibration of combustion equipment according to the installation manual is an integral part of its safety. Inspection activities and frequencies shall be carried out as specified in the installation manual. VISUL INSPECTIONS Regular visual inspection of all connections (air and gas piping to the burner, bolting of the burner to the furnace) and burner flame size and aspect are essential. SPRE PRTS Keep local stock of spark ignitor. It is not recommended to keep local stock of other burner parts. Consult installation manual for burner spare parts and system accessories. 6 www.maxoncorp.com 3M-00E
