摘要： Systems and methods for multi-channel detection of an instability in a furnace comprising a plurality of detectors are disclosed. Each of a plurality of detectors provides a first measurement related to the plurality of burners when the furnace is operating in a stable condition. A stable signal component representation is determined based on the first measurement from each of the plurality of detectors. Each of a plurality of detectors provides a second measurement related to the plurality of burners when the furnace is operating in an unknown state. An unstable signal component representation is determined based on the stable signal component representation and a second measurement from each of the plurality of detectors. An instability is detected based on the unstable signal component representation and an instability threshold.

摘要： A device is coupled to a heat exchanger for mitigating fouling by applying a mechanical force to a fixed heat exchanger to excite a vibration in the heat exchange surface and produce shear waves in the fluid adjacent the heat exchange surface while the heat exchanger is in operation. An electromagnetic driven impulse device induces vibration onto heat exchanger tubes and/or an acoustic wave through the liquid service fluid to reduce fouling. The device can be mounted directly onto the outer part or piping and produces acoustical/vibrational modes onto the tube or near the surface of tubes.
