Abstract:
1. An implosion interruption system for rapidly counteracting transient low-pressure implosion conditions in an exhaust gas section of an exhaust gas-producing plant through which there is a forward flow of plant exhaust gases during normal plant operation that continues for at least a short period of time even after a plant operation interruption which creates a possible implosion condition, said implosion interruption system comprising in combination: a source of a momentum material; one or more jet nozzles disposed in the exhaust gas section, such jet nozzles oriented to produce a stream of momentum material in a direction generally opposite to the forward flow direction of the exhaust gases through that exhaust gas section; one or more conduits connecting the source of momentum material to the jet nozzles, said conduits having a material flow control element; a propelling mechanism that imparts sufficient velocity to a sufficient mass of the momentum material passing through the jet nozzles to produce a substantially immediate reverse pumping effect that tends to arrest the forward flow of exhaust gases and increase pressure upstream of the jet nozzles to effectively counteract an implosion condition; and, a controller that activates the implosion interruption system at an impending implosion condition.
