摘要： PURPOSE:To make it possible to rationally unload granular material from a ship at anchor in the offing in such a way that fluid in a tank installed on shore is sprayed through a relaying float moored in the offing for slurrying granular material in the hold. CONSTITUTION:When unloading, to begin with, a ship 2 with load of granular material 1 is moored near a relaying float Eb, a fluid pressure delivery pipe 4b installed on the relaying float Eb and a slurry transporting pipe 5 are connected to a fluid spraying equipment 13 and a pump 15 installed in a hold 2a of the ship 2. Then a pump 7 installed on a base Ea on shore is set to work, fluid (a) in a tank 6 is delivered under pressure to the spraying equipment 13 installed in the hold 2a, and the fluid (a) is sprayed from this spraying equipment 13 into the granular material 1 in the hole 2a. This results in slurrying the granular material 1, so after transporting it to a separator 8 in the base Ea under pressure of the pump 15, here the granular material is separated from the fluid (a), to be delivered to a yard 11 by the use of a conveyor 11.

摘要： PURPOSE:To land coal efficiently by a method wherein fuel oil in an oil storage tank on land is added to coal in a marine structure to form a slurry, and the slurry is transported to a storage tank on land, from which the slurry is fed to a combustion furnace through a separator. CONSTITUTION:In the case of landing coal 1 loaded in a ship 2 anchored near an offshore relay structure 3, the fuel oil 5 in the oil storage tank 4 on land is injected into the ship 2 through a pipeline 8 and the structure 3, and mixed with the coal 1 to form a slurry. The slurry is transported through a pipeline 9 to the storage tank 10, and temporarily stored there. In the tank 10, the coal in the slurry precipitates 11, and the fuel oil containing an amount of pulverized coal separates from the precipitate 11 as supernatant 12 in the upper portion of the tank 10. The precipitate 11 is reslurried with fuel oil fed from the oil tank 4 through a heat exchanger 14, then transported to a centrifugal separator 18, and the coal separated there is fed to a combustion furnace 23 through a pulverizer 20.

摘要： PURPOSE:To obtain a coal-heavy oil mixed fuel free of sedimentation of coal particles during storage, by the procedure in which pulverized coal and heated heavy oil are continuously supplied into a container turning at high speed while controlling the revolving number of the container, the amount of coal to supply, and the amount of heavy oil to supply in a manner to satisfy respective relations. CONSTITUTION:The raw material coal 1 is charged into the pulverizer 3 by the conveyer 2 and then the pulverized coal is supplied to the high-speed rotary container 14. On the other hand, the heavy oil 13 is supplied through the heater 11 from the oil tank 9 by the oil pump 10 into the container 14, where the revolving number of the cotainer 14, the amount of coal to supply, and the amount of heavy oil to supply are controlled so as to satisfy the relatioship of the formula (G is gravity in the centrifugal force field, t is average staying time in the centrifugal force field, g is the acceleration of gravity, and t is max. storage period). Thus, air and moisture are removed in the centrifugal force field, the coal of a grain size, sedimenting in the centrifugal force field, is restored to the pulverizer 3 again, and only coal of a grain size, not sedimenting in the centrifugal force field, is mixed with the heavy oil to obtain the subject mixed fuel.

摘要： PURPOSE:To arrange so that slurry of preset density may be fed out, by sending out slurry preset density through the gushing out of medium from the upper part of a sump at the bottom of ship hold and then spurting out a medium from the multinozzles at a sump inflow port. CONSTITUTION:Granular substance 2 is cut and crushed by gushing out media such as water, petroleum, etc. from above granular item 2 at the bottom of ship hold through jet nozzle 4. Then granular item flowing into sump 8 is stirred and slurry of preset density is fed out from constant quantity slurry feeder device 9. In addition, an increase in slurry density or the clogging of sump inflow port caused by the collapse of sliding slurry substance 2 is sensed by means of a slurry densitometer 12 or a slurry flowmeter 13. Following this process, a medium is caused to be gushed out from the multinozzles 7 at inflow port for the sump 8. Thus it is always possible to feed out slurry of preset density.

摘要： PURPOSE:To obtain a formed coke of improved quality and productivity, with the advantage of using high-ash caking coal, etc., by blending a caking coal and a non- or sparingly caking coal, carrying out grinding followed by adding a binder to make an aggregate, separating ash particles, then adding the binder and hot water to carry out forming. CONSTITUTION:For example, a caking coal 1 is blended with a non- or sparingly caking coal 2, the resulting blend being ground to obtain a blend coal 9, which is then incorporated wth a binder 12 to perform a kneading followed by adding a liquid medium 23 immiscible with said binder to agitate in the tank 26. Thus, only caking coal particles and non- or sparingly caking coal ones are made into an aggregate through the binder 12, while the ash particles being separated as a suspension in the medium 23. Further, using a screen 31, said aggregate and the ash particle suspension are separated from each other as an unfiltered recovered coal 28 and as a filtered waste liquid 29, respectively. The resulting aggregate is incorporated with a new batch of the binder 12 and a hot water 13 to carry out a kneading, then forming under presure, thus obtaining the objective formed coke 17. EFFECT:Capable of simply incorporating the ash particle elimination procedure into the existing process.

摘要： PURPOSE:A coal-oil mixture is stirred in the presence of water to coagulate the ashes selectively and remove them, whereby the ashes are taken off with a small facility without necessity of waste water deposition possibly causing pollution. CONSTITUTION:A coal-oil mixture from the tank 30 is pressurized with the pump 31, then introduced into the agitation tank 32 where it is generally stirred together with water of a few percent based on the coal vigorously to effect the selective coagulation of ashes by use of water as a binder. The ashes are further granulated and collected as ash A with a centrifuge 3 with a low centrifugal force. In the meantime, the ash-removed product is well mixed in the tank 38 with a precipitation inhibitor 40 from the tank 39 to prepare the stable ash- removed product 42.

摘要： PURPOSE:To extend the type of applicable coal and to deash, granulate and transport the coal while preventing the coal from being powdered by attaching a pasty binder consisting of a pulverized coal and an oil to a powder coal, and agglomerating and rolling the powder coal with addition of water to form a granulated coal. CONSTITUTION:Coal 26 or 27 obtd. by crushing coal 1 by crusher 2 is sent to dry agitator 4, in which the surface of a powder coal particle is coated with a binder film by agitation with addition of binder 33. Coal particle 29 with the attached binder is sent to mixing tank 5, where aq. coal slurry 30 is obtd. by adding water 40. The obtd. slurry 30 is supplied to shape adjustor 6, in which the coal aggregate is rolled, ultimately forming a spherically granulated coal. Then aq. slurry 31 contg. an ash particle of the granulated coal is pour into sieve 7 to obtain granulated coal 33 on the sieve 7. Aq. slurry 32 of the ash particle is separated into ash particle 21 and clear water 39 by solid-liquid separator 8.

摘要： PURPOSE:To take ash particles from a fuel with water efficiently, by dispersing a mixed fuel of finely pulverized coal with an oil, e.g. heavy oil, (COM fuel) in water at a high temperature into drops with agitation. CONSTITUTION:N2 gas at the top 50 of a pressure vessel 4 at a temperature of 100-300 deg.C and a pressure of atmospheric one to 88kg/cm is passed through a conduit 51 and a pump 52, and the moisture is adjusted by waterdrops fed from a water tank 13 and jetted from a moisture conditioning nozzle. The N2 gas is then injected from an injection inlet 56 to form gas bubbles, which rise in a parallel cylinder 28 and an enlarged conical pipe 29 of an inner cylinder 11 in a container 4 while collecting an ash in a COM fuel with the moisture contained therein. The gas bubbles disappear in the interface 61 between the liquid and the N2 gas; however, ash particles near the interface 61 are pushed near the inner wall of the container 4 by centrifugal blades 57 and settle in the water along the inner wall by the aggregation and disappearance of the fine gas bubbled. The settled particles are then expelled from a delivery outlet 16 as a slurry with the water.
