Abstract
The present invention relates to a flameholder (1) for holding a flame (84) comprising a flow of combusting fluid. The flameholder (1) comprises an inlet (32) and an outlet (34) which defines a flow path between them. A magnetic-field generator (10, 20) is arranged to generate a magnetic field (40) across the flow path such that in use the fluid flows in the flow path through the magnetic field (40). As the fluid flows through the magnetic field an electric current is induced in the fluid. This results in a force (86) being generated on the fluid which opposes the flow direction (82). This force acts to hold the flame in place. If the flow path is in the form of a closed loop, in a plane perpendicular to the flow direction (82), then the current (50) induced in the fluid can flow in a closed loop entirely within the fluid.
