Sidewall Horn Igniter Firing System-1

$ P Tubes, and unburned fuel dripping from the horn.COENs system easily overcomes these problems by modifying the atomization process to produce an optimum spray pattern and fuel oil droplet size distribu- tion to match the aerodynamics of the igniter horn. This atomization technique is derived from COENҒs patented > COENs Sidewall Horn Igniter System is a low-cost performance upgrade to the original oil-fired igniter equipment on tangential-fired boilers. Total replacement of igniter components is typically not required. It is the reliable and practical solution for overcoming problems such as high opacity, soot and carbon build-up in the horn, fouled flame rods, plugged Smokeless Igniter Technology . The result is a clean flame that burns all of the fuel and does not produce soot or coke. Additional benefits include improved reliability of the existing flame detection and spark equipment, reduced opacity, and elimination of unburned fuel carryover into the backpass of the furnace, air heater, ESP or baghouse.COENҒs Sidewall Horn Igniters can be applied as either single gun or dual gun systems, with heat input ranging from > 4-12 MMBtu/hr . Depending on the heat input, the COEN Sidewall Igniter can be classified as either an NFPA Class I or Class II Igniter, rated for continuous operation, or Class III.

Sidewall Horn Igniter Firing System-2

Smokeless Igniter Atomizer . Our uniquely designed internal-mix atomizer provides an op- timum spray pattern and fuel oil droplet size distribution within the physical constraints of the igniter horn. A new igniter gun is supplied with the internal-mix atomizer, and is a direct replacement of the original gun. No modifica- tions are required to the mounting assembly. To achieve optimal atomization, control of fuel oil and atomizing air pressures at the igniter gun is critical. As part of the retrofit, COEN supplies oil pressure and atom- izing air pressure regulators that are installed between...

Sidewall Horn Igniter Firing System-3

COEN also offers our state-of-the-art , a flame de- tector for use on sidewall igniters. The is a micro- processor-based programmable digital flame scanner that uses the latest solid state and signal processing technology. The unitized design features an All In OneӔ configuration with an integrated viewing head and signal processor, which eliminates the traditional flame scanner signal processing unit (amplifier) and amplifier cabinet. The mounts directly to the sidewall igniter back plate (no fiber-optic extensions are required), which provides for excellent igniter flame detection and superior...
