Abstract:
A cooled porous plug device in combination with a continuous ignition source is used for burning off explosive mixtures of contaminated radiolytic hydrogen-oxygen gas flow discharged from the steam turbine cycle of a boiling water nuclear power reactor. Optional use of a second cooled porous plug is shown, the second porous plug being located downstream of the burner to function as a heat exchanger to cool the combustion products for controlled condensation of the water vapor.
Abstract:
The main passageway has an annular extraction passageway in the wall thereof. The upstream surface of the annular passageway is contoured so that any fluid entering the annular passageway continues with its momentum unaltered to the exit end thereof. Such a surface is formed by the revolution about the axis of the main passageway of a straight line which is coincident in direction with the momentum of an element of fluid as it enters the annular passageway.
