Abstract: A method of cleaning comprising propelling a sublimable media in a first direction through a discharge wand, inserting the discharge end of the wand into coils of a boiler, impinging on inner and outer surfaces the coils with the sublimable media, which subsequently dissipates or is consumed.
Abstract: A device, system and method permitting on-line explosives-based cleaning and deslagging of a fuel burning facility (31) such as a boiler, furnace, incinerator, or scrubber. A coolant, such as ordinary water, is delivered to the explosives (101) to prevent them from detonating due to the heat of the on-line facility. Thus, controlled, appropriately-timed detonation can be initiated as desired, and boiler scale and slag is removed without the need to shut down or cool down the facility.
