Fireye Surefire II High Energy Igniters

Fireye Surefire II
The Fireye Surefire II High-Energy Ignition System is used for direct spark ignition of most gas or liquid fuels used in oil or gas igniters or main burners. The High-Energy Ignition System is available in various versions. To ensure optimal operation, the first part of the ignition tip should always be in an ignitable fuel-air mixture, during all modes of operation.

After successful ignition, the ignition tip should be disconnected from the power supply and taken
out of the flame. Optionally, when an automated process is required, a pneumatic retraction unit and
systems for hazardous areas are available.

The Surefire II range includes:
  • Integrated power pack with spark rod.
  • Split Power pack and separate spark rod.
  • Portable battery powered Integrated power pack and spark rod.
  • ATEX, Power pack, and spark rods.
  • Co-axial Retractors, with / without integrated solenoid valve.
  • ATEX Solenoid. 

  • Selectable voltage ( 115/230 vac ).
  • Visual indication of spark operation
  • Proof of spark relay
  • Choice of system, Integrated or Kit or Kit with Quick Disconnect
  • Thermal cutout protection integrated in transformer
  • ATEX options
  • Compact "co-axial" retractors
  • Safety bleed resistor discharges capacitors in 120 seconds.

White Paper: Efficiency Improvement Opportunities for Fuel-Based Process Heating Systems

Fuel-Based Process Heating SystemsFuel-Based Process Heating System Optimization

This white paper gives an overview of the most common performance improvement opportunities for fuel-based process heating systems. The main goals of the performance optimization are reduction of energy losses and increase of energy transferred to the load.

Performance and efficiency improvement opportunities can be grouped into five categories:
  • Heat generation: discusses the equipment and the fuels used to heat a product.
  • Heat containment: describes methods and materials that can reduce energy loss to the surroundings.
  • Heat transfer: discusses methods of improving heat transferred to the load or charge to reduce energy consumption, increase productivity, and improve quality.
  • Waste heat recovery: identifies sources of energy loss that can be recovered for more useful purposes, and addresses ways to capture additional energy.
  • Enabling technologies: addresses common opportunities to reduce energy losses by improving material handling practices, effectively sequencing and scheduling heating tasks, seeking more efficient process control, and improving the performance of auxiliary systems. Enabling technologies include:
    • Advanced sensors and controls
    • Advanced materials—identifying performance and efficiency benefits available from using advanced materials
    • Auxiliary systems—addressing opportunities in process heating support systems.

Are you looking for VERI-FLAME Burner Controls?

Burner Controls replacement
The Veri-Flame Burner Monitoring System was discontinued by Eclipse in October of 2018. The product controls the start-up sequence and monitors the flame of gas, oil, or combi­na­tion gas/oil burners. It was a very popular product sold world-wide. Many OEMS adopted it, and there are thousands of installations all over the USA.

As you can imagine, when a product is discontinued, it creates an immediate need a replacement that matches the original as closely as possible. Without a direct, drop-in replacement, engineers and service technicians must search out functionally similar products, and then come up with adapter kits for retrofit - a huge hassle and time consuming ordeal.

Combustion Technology, LLC, a Vancouver, Washington company specializing in process heat, combustion controls and combustion systems, has a solutions for anyone looking for a Veri-Flame replacement.  If you are an OEM trying to support an existing customer base, service tech or end user wanting to avoid a costly and time consuming retrofit, Combustion Technology can help.

Combustion Technology stocks direct replacements for many of the most popular units, including bases and scanners with same or next day shipping. These are not rebuilt or reconditioned. They are new units, manufactured by the same company that built Veri-Flame controllers for Eclipse. All replacement units carry the same agency approvals as the originals.
Burner Controls replacement

Finding your direct replacement is easy. Just find the controller model number located on the back of the plug-in module and contact Combustion Technology for price and delivery. No re-wiring, just plug in the new unit when it arrives. For more information, visit

Industrial Source Book: Improving Process Heating System Performance

Improving Process Heating System Performance: A Sourcebook for Industry is a development of the U.S. Department of Energy (DOE) Advanced Manufacturing Office (AMO) and the Industrial Heating Equipment Association (IHEA). The AMO and IHEA undertook this project as part of a series of sourcebook publications developed by AMO on energy-consuming industrial systems, and opportunities to improve performance. Other topics in this series include compressed air systems, pumping systems, fan systems, steam systems, and motors and drives.

This Sourcebook outlines opportunities for energy and performance improvements in process heating systems, and is intended to help the reader identify improvement opportunities in their own facilities. This Sourcebook is not a substitute for a rigorous engineering-based assessment and evaluation of the technical and economic potential of any process heating improvement.
