Blowing down a boiler is letting out a portion of the water, so as to carry off the loose scale, mud, or sludge that may accumulate on the bottom of the boiler.
The mud orsludge would form into scale if allowed to remain.
Mr. Sludge is not so much to blame: the people at length push the thing so far that he is obliged to cheat in self-defence.
Mr. Sludgeis a bad Yankee, as well as impudent pleader.
Sludge must be right in this; otherwise the theologians would not have had such a successful run.
To our astonishment we ran on past the Cape with clear water or thin sludge ice on all sides of us.
We could have gone farther, but the last sludge ice seemed to be increasing in thickness, and there was no wintering spot to aim for but Cape Armitage.
The use of hickory wands for stirring up sludge in drill holes, and increasing the speed of drilling.
Browning does not carry the idea of repression as far as I do, Sludge producing clouds of rationalisations to cover his inconsistencies.
Mixtures of sewagesludge and municipal solid waste are first composted and after cooling, the half-done high C/N compost is shallowly spread out over crude worm beds and kept moist.
While the vane is rapidly whirled, the sludge is gradually let down into the revolving water, till the quantity is sufficiently great.
Cooling brings back the sludge to the pasty condition, and is therefore necessary for the due separation of the different bodies.
The filtering material used could be gradually prepared from the sludge obtained after electrical treatment, unless it could be more profitably sold as a manure, and I am not a believer in the value of sewage sludge in large quantities.
The practical result of the process is a very rapid and complete clarification of the sewage, which enables the sludge to separate freely.
The generator, also, may conveniently be so constructed that it is fed with carbide from above the roof, and emptied of lime sludge from below the floor of the vehicle.
The carbide should be completely decomposed in the apparatus, so that lime sludge discharged from the generator shall not be capable of generating more gas.
It would be a desirable refinement to give the bottom of the vessel a slope to the mouth of e, or to some other spot where a large-bore draw-off cock could be fitted for the purpose of extracting any sludge of lime, &c.
The clear lime-water will then be pumped back into the generator for further use, and the almost solid sludge will be ready to be carried to the pit where it is to be buried.
Such discoloration is of little moment for most of the uses to which the sludge may be put.
There is a stirrer actuated by a handle (9) for preventing the sludge choking the sludge cock.
The lime sludge is discharged from time to time through the cock E, being stirred up by means of the agitator C with handle D.
When the sludge is discharged water is added through M to the proper level.
The foregoing remarks about the use of oil manifestly only apply to those cases where it is used in quantity and where it ultimately becomes mixed with the sludge or floats on the water in the decomposing chamber.
There is an eccentric stirrer for thesludge and a large-bore cock for discharging it.
It is evident that some of the matter that should remain in the septic tank and be removed as sludge will be carried into the anaerobic filter.
The amount of accumulated sludge is relatively small, and the operation of cleaning is not necessary more than twice a year and is not the disagreeable task one might suppose.
If the septic tank is of insufficient size to readily digest the sewage, the accumulation of sludge in the anaerobic filter will be greater than should occur.
There really are touches of resemblance in it to Browning, especially in things like Mr. Sludge the Medium.
As sludge collects, it is removed with a species of scraper, fashioned from the end of an iron bar.
The bit is hollow, and when it becomes full of sludgeproduced by its incessant tapping, it is withdrawn from the hole, cleared out, and entered again.
The Prince is a psychological study, like Mr. Sludgethe Medium, and Bishop Blougram.
Soak-pit sludge has a distinctly greater value as manure, on account of the greater proportion of dung proteins.
The sludge possesses some value as a manure, especially if from the soak pits on account of the greater nitrogen content.
The sludge from the pits of the limeyard contains, in addition to much lime and chalk, a certain proportion of protein matter.
Steam spray burners of the older types had disadvantages in that they were so designed that there was a tendency for the nozzle to clog withsludge or coke formed from the oil by the heat, without means of being readily cleaned.
Strainers should be provided for removing sludge from the fuel and should be so located as to allow for rapid removal, cleaning and replacing.
From the "levitation" of the axe at one end of a period of near three thousand years to the "levitation" of Sludge & Co.
The sludge was treated in fancy amalgamators, especially in one with a pan and revolving arms, probably evolved out of the inner consciousness of some gentleman in Paris.
The fog was so thick that I may safely say we did not see more than fifty yards from the ship, whereas we ought to have had the midnight sun; ice and snow-sludge were so thick that at times we lay still.
The last two days before our departure had been calm, and a thick, dense sludge lay over the whole bay; so dense was it that the Fram lost her way altogether, and we had to keep going ahead and astern until we came out into a channel.
But let Richard Sludge alone; I have not been cock of the roost here for nothing.
At this moment Sludgeapproached to bid them farewell.
