Ignition tests with brush discharge between a spherical electrode and a PVC plate in hydrogen–air mixture

In this work, we report the ignition potential between an earthed spherical metal electrode and a charged insulating plate in hydrogen–air mixture. The test results indicate that it is very difficult to generate brush discharge when the surface potential of the plate center is less than −10 kV. And...

Summary:In this work, we report the ignition potential between an earthed spherical metal electrode and a charged insulating plate in hydrogen–air mixture. The test results indicate that it is very difficult to generate brush discharge when the surface potential of the plate center is less than −10 kV. And it is very difficult to ignite the hydrogen–air mixture when the surface potential of the plate center is less than −20 kV. The ignition can be generated when the range of the hydrogen concentration is 20–25%.
