HTS Eclipse – PrimeFire 100

Overview

The Honeywell PrimeFire 100 is an oxy-fuel burner designed for glass melting furnaces and other high-temperature industrial applications. It produces a conventional cone-shaped flame with high luminosity and supports multiple fuel types — including natural gas, light oil, and heavy oil — with the ability to switch between fuels in a few minutes without major downtime.

The PrimeFire 100 has become an industry standard for glass furnace applications, offering greater operational flexibility, improved melter efficiency, extended refractory life, and a proven no-maintenance design. Its adjustable flame shape allows variation in flame coverage to suit melter size and temperature profile, and its higher firing range makes it a strong choice for float glass furnaces.

Features & Benefits

• Long and lazy flame profile with high luminosity for uniform heat distribution across the melt surface
• Adjustable flame shape allows operators to match flame coverage to melter size and temperature profile
• Lower flame temperature reduces thermal stress on refractory and extends furnace lining life
• Lower NOx and particulate emissions compared to conventional air-fuel burners
• No-maintenance design reduces operating costs and unplanned downtime
• Ideal for on-the-fly fuel switching — change from gas to oil or vice versa in a few minutes
• Common burner and burner block components across fuel modes simplify spare parts management
• Extended turndown ratio supports a wide operating range
• Proven field and laboratory performance across decades of glass industry use
• Oil burning: lower atomizing oxygen and compressed air pressure requirements reduce utility consumption
• Lower precombustor (burner block) and nozzle operating temperatures extend component service life
