  • Experiments on plasma assisted combustion using a dielectric barrier surface discharge

    • This paper report on experiments performed using a dielectric barrier surface discharge to increase the combustion rate in a Bunsen-type burner. The burner has a coaxial geometry where premixed fuel-air flows in the outer annular tube while a jet of air can be injected through the central tube, thus increasing turbulent mixing and flame speed. When the central jet is used the power density but not the total power of the flame increases and gives the possibility of studying the influence of the discharge as a function of power density in the flame. It is found that, although the total power in the flame is held constant, when the power density in the flame increases the influence of the electrical power on the flame characteristics decreases.

  • Measuring breakdown voltage for objectively detecting ignition in fire research
  • 2013
  • Ingår i: Measurement science and technology. - : IOP Publishing. - 0957-0233 .- 1361-6501. ; 24:10
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper presents a method intended for detecting the initiation of combustion and the presence of smoke in confined or open spaces by continuously applying an intermittent high-voltage pulse between the electrodes. The method is based on an electrical circuit which generates an electrical discharge measuring simultaneously the breakdown voltage between the electrodes. It has been successfully used for the detection of particle-laden aerosols and flames. However, measurements in this study showed that detecting pyrolysis products with this methodology is challenging and arduous. The method presented here is robust and exploits the necessity of having an ignition system which at the same time can automatically discern between clean air, flames or particle-laden aerosols and can be easily implemented in the existing cone calorimeter with very minor modifications.
