blowing thru a mandoor in a kraft recovery boiler

[bangandclean]

This patented bang&clean® on-line boiler cleaning technology uses shock- or pressure waves, which are generated by dosed and controlled explosions of normal industrial gases, for the removal of slag, soot and any accumulations on boiler tubes and walls, but also in ash hoppers, ESPs etc. Unfortunatley does the movie show a crew that does NOT follow the technology vendor's safety requirements and procedures.

Är det sodapanna 7 på skutskärs bruk jag ser?

[Follbring79]

@Norrsundracing Nej det är SP3 på hemlig ort!!!!!

I seem to recall hearing they also use det-cord for something similar to this, as well? Maybe only imagined such. But even though I'm not a boiler-tech in any way, I'll hafta agree---I'd want more on than a sleeveless-T, an' a light-duty Plexiglas shield on what appears to be only a Class-2 hardhat, if I EVER attempted such a job as this...!!!

[soupito]

Yup ! Looking at that poop, is reason enough never to work in another recovery boiler house.

Looks like a job for the "GU" man.

They are inserting a blast charge into the boiler...this knocks all heavy debris like crystallized coal (clinkers) down into the ash hopper. Essentially making it safe to enter to do work, etc.

@crstella I thought there was pipes and what not in there. How do they not get damaged?

[crstella]

@bobby472 There are steel tubes that are inside, the shockwave is what knocks the heavy debris down. they arent inserting something that shoots shrapnel. Alot of the time we open hatch doors to the boiler and simply shoot chunks of coal down with shotguns. The tubes within the boiler are pretty hefty and can withstand considerable forces.

[bobby472]

@crstella ahh. The way my teacher was talking about the inner tubes, they seem very thin.

[crstella]

@bobby472 Well, steel tubes do get worn out and thin over time. But Ive never heard of a boiler "De-Slag" damaging tubes. Depending on the time the boiler was built and who designed it usually determined how thick the tubes were. B & W, Combustion and Foster & Wheeler are typical design types.
