It's called Embedded Combustion™ and it's changing the way industry is going about the chalenges of non-contact IR drying and curing.  Embedded Combustion™ is a process that directs the combustion of the gas / air premix to initiate 1/8" within the outer face of the 1" thick IR emitter.  This increases the emitter / hot gas contact surface area and residence time, and reduces the dt (temperature difference) between the emitter structure and the hot gases leaving the emitter.

For you it simply means 3 times the heat transfer efficiency (or to put it another way, the same amount of IR outout for only 1/3 the fuel input).

With Marsden, dry faster, safer and more efficiently.

The Secret of Embedded Combustion™ lies between finger and flame

You do not burn your finger when you pass it quickly through a flame.  You can even hold your finger alongside a flame without burning because the flame emits very little Infrared.  These two demonstrations help to understand the advantages of Embedded Combustion™ in a gas Infrared emitter.

The hot gas molecules in the flame heat the gas infrared emitter mostly by conduction (physical contact) not by thermal radiation (IR).  Conduction energy transfer is increased directly proportional to residence time, surface area and dt (temperature difference).

In a non-contact IR drying system, Embedded Combustion™ greatly improves IR efficiency by increasing the time the flame is in contact with, and the area of contact of, the emitter structure.  The result?  3 times the IR heat flux compared to metal fibre surface combustion burners with the same fuel input.

Embedded Combustion™ coupled with a very high emittance, means Marsden gas IR Emitters produce more IR output at lower, more fuel-efficient operating temperatures than metal fibre surface combustion burners.

Marsden Embedded Combustion™ IR emitter operational and safety features include:

• Off to full power in < 5 seconds
• Cool to the touch in 1 second
• Metal-free emitter for long, full power life
• Almost zero NOx emissions
• Radiant outputs to 141 kW/m²/hr
• Homogenous 25mm thick Emitters to 5.6 m wide
• Oven ready to 430°C ambient

The Embedded Combustion™ emitter has an IR heat flux (energy transfer) of 45,000 BTU's/ft²/h (141 kW/m²/h) at 87,000 BTU's/ft²/h (276 kW/m²/h) input.

The metal fibre surface combustion burner has an IR heat flux of 24,000 BTU's/ft²/h (74.2 kW/m²/h) at 152,000 BTU's/ft²/h (480 kW/m²/h) input.

The Marsden Embedded Combustion™ Emitter's IR heat flux is more than 3 times greater than the surface combustion burner's IR heat flux for an equal fuel input.
