Abstract
Apparatus and methods are disclosed for rapidly counteracting a transient low-pressure condition, that can occur intermittently in the exhaust section of a power plant or other such industrial facility upstream of exhaust fans as a result of an event that interrupts the generation and/or flow of exhaust gases, using jet nozzles disposed in the exhaust section and connected to a source of pressurized air or other suitable momentum material. By orienting the jet nozzles in a direction generally opposite to the flow of exhaust gas and actuating the system to release a burst of compressed air, for example in the event of a power plant interruption, the low-pressure condition can be ameliorated preventing damage to the exhaust section.
