SYSTEM AND METHOD FOR DETERMINING A LOCATION OF FOULING ON BOILER HEAT TRANSFER SURFACE

摘要

Detecting fouling of a heat exchanger of a boiler includes emitting a spray of pressurized fluid from a nozzle of a sootblower element when the nozzle is adjacent to a surface of the heat exchanger, and sensing a value indicative of a reactive force created by an impact of the pressurized fluid on the surface of the heat exchanger and translated back to the sootblower element through the spray of the pressurized fluid. The method also includes determining when a substantial deposit is on the surface of the heat exchanger indicating fouling based on the value indicative of the reactive force.

1. A method of detecting fouling of a heat exchanger of a boiler, the method comprising:
emitting first and second sprays of pressurized fluid from first and second nozzles of a sootblower element; generating a value indicative of one or more reactive forces created by impact of one or both of the first and second pressurized fluid sprays on the heat exchanger or one or more substantial deposits on the heat exchanger and translated back to the sootblower element through one or both of the first and second sprays of the pressurized fluid; and determining when a substantial deposit is on the heat exchanger indicating fouling based on the value.
