摘要： PURPOSE:To perform safe operation by reducing vibration even when the supply amount of an object to be ground is little and to enhance the response of the amount of a product at the time of a sudden change in the supply amount. CONSTITUTION:The object 2 to be ground supplied to a table 9 is dried by the hot air blown up around the table 9 rotating around a drive shaft and finely ground by the table 9 and a plurality of the rollers 10 rotating while pressing the upper surface of the table 9 and, if the supply amount of the object 2 to be ground is little when the finely ground object 2 is guided to the outside of a roller mill from the outlet provided to the upper part of the roller mill by hot air, outlet temp. 8 is lowered and the moisture of the object 2 to be ground on the table 9 is increased to lower the grinding properties of the object 2 to be ground and the layer of the object 2 to be ground between the rollers 10 and the table 9 is made thick not only to reduce vibration but also to increase the holding amount in the mill. When the supply amount of the object to be ground is much, the outlet temp. is made high and the grinding properties of the object to be ground is improved to reduce the holding amount in the mill and the change of the holding amounts in the mill at the times when the supply amount is little and much is reduced to enhance the response of product quantity to the change of the supply amount.

摘要： PURPOSE:To prevent the explosion of powdered coal by lowering the concn. of oxygen in a coal pulverizer by providing a drain separator separating the drain contained in inert steam and a drain trap to the charging route of inert steam to a coal pulverizer., and mounting a drain discharge route discharging drain. CONSTITUTION:At the time of the usual operation of a coal pulverizer 2, an inert steam valve 8 is closed so as to prevent inert steam from entering the hot air charged to the coal pulverizer 2 from a hot air duct. The drain in the inert steam adjusted to predetermined pressure and lowered temp. by a pressure reducing valve 4, and a temp. lowering device 5 is always separated and removed by a drain trap 6 so that the inert steam is immediately charged when the inert steam valve 8 is opened in this state and the separated and removed drain is discharged as it is. At the time of the temporary stop of the coal pulverizer 2, the drain discharge valve 7 bypassing the drain trap 6 is opened, before the inert steam valve 8 is opened and the drain in the steam present on the upstream side of the inert steam valve 8 is perfectly discharged. By this method, the damage of a cast part is certainly prevented.

摘要： PURPOSE:To simplify the equipment required in charging by providing a powdered oxygen absorbent charging means scattering a powdered oxygen absorbent on the surface of raw coal fed by a belt conveyor as an inert medium and scattering the powdered oxygen absorbent when a coal pulverizer is started and stopped. CONSTITUTION:An oxygen absorbent storage and charging apparatus 22 having a powdered oxygen absorbent 21 stored therein is arranged at the position above the belt conveyor 13 of a coal feeder 3. When a coal pulverizer 5 is started and stopped, the oxygen absorbent storage and charging apparatus 22 scatters the powdered oxygen absorbent 21 on the coal 11 on the belt conveyor 13. The scattered powdered oxygen absorbent 21 falls through a coal feed pipe 4 along with the raw coal 11 to be well mixed with the raw coal 11 at the time of the collision and scattering on a bowl 7, and the surface oxygen concn. of the raw coal is reduced and the concn. of oxygen in the coal pulverizer is also simultaneously reduced. By this method, handling also becomes easy.

摘要： PURPOSE:To prevent interruption of flow of particles and wear of blades as well, by providing an annular body which connects blades around the center of rotation. CONSTITUTION:Blades 1 are connected to a lower cone 5 constructed on a rotor 7 in a framework manner and on the peripheries of upper spokes 6 through lower fixing plates 3 and upper fixing plates 4 for blades respectively approximately in vertical direction so as to encircle the rotor 7, wherein a reinforcing ring 2 passes horizontally through the middle part of each of the blades 1 to connect them with each other. When the rotor 7 rotates, centrifugal forces acting on the blades 1 exert outward loads thereon so as to cause deflection in the central portion of the blade; however, such deflection is avoided by the reinforcing ring 2. Consequently, area of the opening between adjacent blades 1 in the direction of flow of particles can be made greater, resulting in improved classification property.

摘要： PURPOSE:To facilitate the entry of ash into a jet pulsation pump and as well as suppress the fluctuation of the density of slurry by a method wherein the sum of the volume of the cooling feed water and of the jetting water to be supplied to a clinker hopper is kept larger than the volume to be sucked by said jet pulsation pump. CONSTITUTION:The hopper 1, which is connected to the furnace bottom tube of a boiler, is water-sealed by immersing a sealing plate 10 fixed at the lower part of said tube into the cooling feed water 9 stored in a sealing trough 8 and, after that, said water 9 is uniformly led into the hopper 1 along the whole periphery of the hopper 1. Then, the water 9 is discharged from a water intake port 11 through an overflow pipe 12 in order to maintain the temperature of the water within the hopper 1 at the fixed value. In order to discharge ash, the jet pulsation pump 6 and a clinker crusher 7 are put into operation. Henceforth a gate 3 is open and then water is jetted from nozzles 14 under the controlled conditions that the sum of the volume of the water jetted from the nozzles 14 and of the cooling feed water 9 is rendered to be slightly larger than the volume to be sucked by the pump 6.

摘要： PURPOSE:To accomplish automatic operation of the hopper such as a clinker hopper disposed at the bottom of a furnace, by providing a transmitter and a receiver at a lower portion of the hopper in the manner that they face toward each other, and starting ash discharging operation when a signal from the transmitter is received by the receiver. CONSTITUTION:The clinker hopper disposed at the bottom of the furnace is filled with water to a reference level 11, and ash 10 accumulated inside the side wall 1 of the hopper is carried into a clinker crusher 5 via a through-gate 2 opened and closed by a cylinder 4 and an enclosure 3. In the crusher 5, the ash is crushed into pieces, which are then drawn out by a jet pump 7 and carried via transport pipe 6 to an ash discharging station. In the above arrangement, a transmitter 12 is fixed to the side wall 1 at a portion thereof facing the opening 9 which is opened and closed by the gate 2, and a receiver 13 is fixed to the inner wall of the enclosure 3 in the manner that it face the transmitter 12. In discharging ash, it is known that the discharging of ash has been completed, when a signal from the transmitter 12 is received by the receiver 13.

摘要： PURPOSE:To ensure seal while compactly housing a block plate into this damper, by pushing the block plate against a duct port by using a pantograph mechanism. CONSTITUTION:A moving top 26 is left shifted by means of a piston rod 29 of a cylinder 28 for clamping. Thus, both levers 41, 45 tilt, and the lever 41 transfers a block plate 17 in the arrow head C direction through a connecting rod 40. Since the block plate 17 is moved in the arrow head C direction, a seat packing 18 parts from a seal frame 16 with which the packing has contacted, and the block plate 17 locomotes to a location 17' of a two-dot chain line. A main shaft 22 is revolved in the arrow head D direction through an opening and closing lever 54 and a pin 55 by working a cylinder 56 for opening and closing. The block plate 17 is shifted in the arrow head E direction by operating the cylinder 28 for clamping, brought close to a side-wall of a damper body 11 as shown in the figure 17'' and compactly housed.

摘要： PURPOSE:To simplify the construction, by transmitting the load from the back stay directly to the opposed back stay. CONSTITUTION:A free hole 26 is provided not to limit the longitudinal expansion in the back stay consisting of a boiler furnace wall 2, back stay 1, stay lap 20, 22 and bolt 21, bracket 23, 24 is installed to the end of opposed back stay 1 by a pin to connect. Thereby relative thermal expansion of the back stay to the boiler furnace wall 2 is free the furnace pressure on the boiler furnace wall 2 is supported with a back stay 1, transmitted directly to the opposed other back stay from the bracket 23, 24 pin 25 installed to the end of opposed back stay 1. Consequently load transmission can be made without a tension plate and corner fittings.
