A method and apparatus for on-line wash-down of a heat sink media bed in a regenerative heat exchanger of a regenerative fume incinerator is disclosed. When a heat sink media bed requires cleaning, the selected regenerative heat exchanger is cooled while the remaining regenerative heat exchangers are operated in their normal mode of operation. When the selected media bed reaches a temperature which is less than the thermal-shock temperature of the media material, a cleaning fluid is sprayed on the media surfaces through spray-pipes which are installed within the media bed. After the media surfaces are washed down, the selected regenerative heat-exchanger is reverted back to its normal mode of operation. The regenerative heat exchanger can also be automatically burnt-out of deposited gasifiable matter prior to the wash-down. Random or sequential burn-out and wash-down of the regenerative heat-exchangers can be performed. The apparatus can also be used to suppress fires within the media bed by spraying cold water on the media bed when a rapid rise in temperature is detected within the media bed.
A method of washing the heat sink media in a selected regenerative heat exchanger of a Regenerative Fume Incinerator while the remaining regenerative heat exchangers of the Regenerative Fume Incinerator are on-line with the process, the selected regenerative heat exchanger having an upper section and a lower section, and at least one spray pipe installed in between the upper and lower sections, the spray pipe connected to a source of cleaning fluid, the spray orifices on the spray pipe being directed towards an upper surface of the lower section of the heat sink media within the selected regenerative heat exchanger, the method comprising the following steps:
