Abstract (en)

A device 10 for removing a blocking material in a quenched ash extractor drain pipe 2 of an incineration system is provided. The device 10 comprises: a pipe 11; a connecting part 12 configured to connect the pipe 11 to a gate valve 30 of the quenched ash extractor drain pipe 2; and a ram 13 with a first end 16 configured to break the blocking material and to be slidably guided through the pipe 11 into the quenched ash extractor drain pipe 2. Hence the device 10 provides an improved solution to remove more safely and effectively the hot water from a quenched ash extractor 222 then therefore the blockage of incinerator bottom ashes in the quenched ash extractor 222 of the incineration system.
