Abstract:
1. A flashback protector for limiting the propagation of a flame towards a fuel supply, the flashback protector comprising: a downstream side and an upstream side defining a flow path between them, a magnetic-field generator arranged to generate a magnetic field across the flow path, the magnetic-field generator comprises a first pole piece having a cavity within which a second pole piece is located in such a way that an opening is formed between the first and second pole pieces which in use provides the flow path for the fluid and across which the magnetic field is generated, wherein when in use and a flashback occurs fluid flows in the flow path towards the fuel supply through the magnetic field, which then induces a flow of current in the fluid, thereby generating a force on the fluid in a direction away from the fuel supply, wherein the flow path is in the form of a closed loop in a plane perpendicular to the flow direction such that in use the induced current can flow entirely within the fluid.
