Radiant burner MR-86

The MR-86 is a 6” x 8” gas-fired infrared surface combustion burner. Its metal alloy foam emitter and stainless steel body make it an outstanding choice for many food production processes such as browning, pre-cooking or roasting meat. Its high radiance enables rapid searing of meat, allowing the product interior to remain moist. The MR-86 is also excellent for a wide variety of industrial applications requiring corrosion resistance, high heat flux density and low combustion velocity. Performance The MR-86 has a maximum capacity of 17,000 BTU at 3.5” W.C. and reaches a maximum emitter temperature of 1700°F. It is designed to operate using an oxygen level of 19.1%-19.3%. Its radiant output is approximately 65% infrared and 35% convective heat. The MR-86 has a turndown ratio of 2.5 to 1, allowing it to run at lower temperatures (e.g., 1100°F) during line slowdowns or when processing more heat sensitive product. It’s ability to quickly cool down prevents product damage in the event of a line stoppage. Upon re-start, the burner will quickly return full fire, reaching peak temperature in seconds while maximizing labor efficiency and minimizing energy costs. The MR-86 emitter is made of fine porosity metal alloy foam that provides an even combustion surface and consistent air/gas flow to prevent internal flashing. The emitter is enclosed in a stainless steel frame that is welded onto the housing and sealed with a high temperature gasket to eliminate escape pathways and ensure optimum air/gas flow. Since this is a flat-faced burner, it can be placed close to the product, enabling faster line speeds and enhancing energy efficiency.
