摘要： PURPOSE:To make the vertical type roller mill excellent in grinding capacity such as biting of particles to be ground by regulating the ratio of radius of curvature of the grinding surface of a grinding roller to the radius of curvature of the groove surface of a grinding race to the range of specified value. CONSTITUTION:A discoid grinding table 3 rotated in the horizontal surface is provided to the inside of a mill casing 13. Further a grinding race 5 having a groove surface of a circular arc-shaped cross section is provided concentrically with the outer circumference of the table on this table 3. A plurality of grinding rollers 6 have the circular arc-shaped grinding faces which are inscribed to the groove surfaces of the grinding race 5 and have prescribed width. These rollers 6 are provided so as to be pushed on the grinding race 5 by the required pressure. Furthermore a raw material feed pipe 2 for supplying material to be ground is provided above the grinding table 3. The ratio (Rrol/Rrac) of the radius of curvature Rrol of the grinding face of the grinding roller 6 to the radius of curvature Rrac of the groove surface of the grinding race 5 is regulated to a range within 0.6-0.75. As a result, the roller mill is made excellent in grinding capacity such as biting of particles to be ground.

摘要： PURPOSE:To reduce the concentration of soot without increasing the density of NOx contained in the exhaust gas by installing a fuel spray atomizer where a plurality of ejection holes are divided into two groups or more, and the adjoining ejection holes are laid out in positions having different distances from the axial center of said atomizer. CONSTITUTION:An atomizer comprises a chip main body 1, a back plate 4, and a cap nut 11 of said atomizer. Fuel 2 is distributed mixing ejection holes 10alpha, 10beta and 10gamma respectively virtually on an equal basis via a fuel supply hole 9alpha through a fuel communication pipe 5 where a plurality of opening are board on the back plate 4 of the atomizer. The fuel 4 and an enhanced fine particle medium 3 are collided and mixed with each other in the respective ejection holes 10alpha, 10beta and 10gamma, turned into more enhanced fine particles, atomized, and ejected from the atomizer. The flow of fuel thus atomized is mixed with the combustion air, thereby forming flames. Six ejection holes 10alpha, 10beta and 10gamma are distributed on a circumference whose radial diameters are different from each other, centering on the axial center of the atomizer. The fuel density in the atomized fuel flow can be shaded while the exhausted NOx density can be reduced by dividing burner flames into two sections.

摘要： PURPOSE:To efficiently produce slurry having uniform quality by previously detecting grindability of a feed crushed with a primary crusher and controlling both the number of revolutions of a wet mill and supply quantity of the feed to the mill on the basis of this detected result. CONSTITUTION:Coal in a raw coal bunker 1 is fed to a primary crusher 3 from a coal feeder 2 and crushed and coarse particles F are separated from fine particles G by a classifier 21 and returned to the primary crusher 3. The fine particles G are fed to a wet ball mill 5 with a coal feeder 4 of the mill and herein water B proportional to the feed quantity of coal, a surfactant C and a pH regulating agent D, etc., are added and the mixture is mixed and pulverized. In this case, the supply quantity of coal is set with a setter 300 and in addition thereto, the index of grindability of the feed is set with a setter 400 and this is sent to a mill controller 100 as an advance signal. The controller 100 calculates the number of revolutions of the wet mill 5 on the basis of both signals and outputs a signal to a regulator 37 for the number of revolutions of the mill and the prescribed number of revolutions is decided.

摘要： PURPOSE:To easily and speedily take a measurement with reliability by measuring the length of the continuous part of slurry discharged from a nozzle provided atop of a slurry conduit and the spouting pressure of the slurry from the nozzle. CONSTITUTION:Slurry fluid (CWM) 1 which flows in a transport pipe is branched from a CWM conduit 4 mounted on a conduit seat and spouted from the nozzle 6 provided atop through an elastic deformation part (bellows) 5 to become a liquid jet 9, which separates into liquid drops 18. The length Lj (separation length) of the continuous part of the jet 9 is measured after the length becomes stable. The jet pressure is found through a manometer provided to the transport pipe and the viscosity of the CWM is calculated from a correlation expression found from those values, the diameter Dj of the nozzle 6, etc. Further, when an exciter 7 added to the nozzle 6 vibrates the nozzle 6, the jet 9 is disordered forcibly, so the separation length becomes short and its variation is reduced, so that accurate measured values are obtained. A sine wave signal from an oscillator 21 is voltage-amplified by an amplifier 20 and applied to the exciter 7.

摘要： PURPOSE:To automatically prepare a large amount of a slurry having predetermined concn. and viscosity, by providing a moisture detection means for detecting the moisture of raw coal and a supply means for controlling the supply amount of a slurry constitutional material on the basis of the signal from the detection means. CONSTITUTION:When the supply amount of water is controlled corresponding to the change in the moisture content of raw coal, the slurry in a mill 18 can be held to predetermined concn. and viscosity. A control part 33 operates the total amount of the moisture supplied to the mill 18 from the moisture content in the raw coal measured by a measuring part 32 and the supply amount of water already known at the time of the transmission to a valve 28 in the past and transmits a water supply amount control signal to the valve 28 on the basis of the operation result. The valve 28 changes the opening and closing amount of a flow rate on the basis of the signal to adjust the supply amount of water to the mill 18. Further, the supply amount of coal per hr of a coal feeder 16 is constant and the concn. and viscosity of the slurry in the mill 18 are adjusted to desired values.

摘要： PURPOSE: A slurry mixture which is obtaind by forming slurries by the wet process and mixing 2 slurries different in particle sizes is deashed, dehydrated ane wet-crushed in the presence of a surfactant to give a deashed coal-water slurry which contains reduced content of ashes and has high fluidity even in high coal concentration.
CONSTITUTION: (A) A slury which is prepared by wet-crushing coal until the weight-average particle size becomes 30W80 micrometers and (B) another slurry which is prepared by wet-crushing coal until the weight-average particle size becomes 5W20 micrometers are mixed so that the weight ratio becomes 2/8W8/2, then deashed or each coal slurry is deashed, then mixed. The resultant slurry is dehydrated until the water content becomes less than 40wt%, then wet-crushed in the presence of a surfactant, preferably an anionic or nonionic surfactant to give the objective deashed coal-water slurry.

摘要： PURPOSE:To measure continuously the viscosity of slurry by installing a pressure drop measuring instrument and a flow meter in some section of piping, and letting the slurry flow through the piping. CONSTITUTION:The flow meter 49 which measures the flow rate of the slurry is provided on a differential pressure measurement line 41 at the exit side of a pump 51. The differential pressure measurement line 41 has a smooth internal surface and a differential pressure gauge is fitted in some section by using a flange 43, etc. The differential pressure gauge 42 uses a diaphragm type so as to prevent the slurry from flowing in and freezing, and the pressure of the slurry is received by a diaphragm and sent to a differential pressure transmitter 46 through a capillary tube 44 which is charged with silicone oil. The slurry E is sucked from a samp tank 52 bu a pump 51 and admitted intp the measurement line 41, and its flow rate and differential pressure are measured by the flow meter 49 and differential pressure gauge 42. Signals from the differential pressure transmitter 46 and a flow rate oscillator 50 are processed by a computing element 47 to calculate and display the viscosity of the slurry on an indicator 48 as well as the slurry mean flow velocity and differential pressure in the piping.
