摘要： PURPOSE:To prevent the temperature of main steam from lowering, and to set a turbine side steam condition to an optimum value in restarting the unit by operating a turbine bypass valve adapted at the outlet part of a boiler and a superheater bypass valve adapted at the intermediate part of a superheater for the boiler in conjunction with each other. CONSTITUTION:The streams of boiler water and steam in the state of a plant operation prior to the generation of a first cutback (FCB) and feed water passing through a boiler water feed pump 61 and a high-pressure feed water heater 62 are fed into a boiler 63. The fluids passing through the boiler 63 are converted into superheated steam by superheaters 67, 68 and 69 to be sent to a turbine 73. According to the FCB generation, a turbine regulating value 75 is operated to be rapidly chocked up to a house independent load. On the boiler side, the quantities of water and fuel to be fed to the boiler are adjusted so as to be well balanced with a turbine load, while excessive steam in the boiler is released by the opening operation of a solenoid type escape valve 72, a turbine bypass valve 71 and a superheater bypass valve 70 to prevent the abnormal increase of a boiler pressure. In order to provide for the restarting of a unit, the boiler pressure is made to drop by about 140 kg/cm g. The boiler pressure is dropped by means of the superheater bypass valve 70 adapted at the intermediate part of the superheater, and after the pressure is once dropped, the boiler pressure is controlled by switching over the superheater bypass valve 70 to the turbine bypass valve 71.

摘要： PURPOSE:To reduce a quantity of a high level CO produced at the vicinity of a side wall and at a corner part, by a method wherein small auxiliary OA ports are formed, being positioned closer to a side wall than an outermost burner row, and OA ports in a combustion mechanism take the form of a turnable circular type. CONSTITUTION:Small auxiliary OA ports 24, being different in a swhirling direction from that of other OA ports 23, are formed in parallel at two corners in the vicinity of the side wall of a furnace. Namely, a clockwise swirling stream is produced in an air current at a burner part and an air current in conventional OA ports so that the air currents bend leftwardly, and meanwhile a counterclockwise swirling stream is produced in the air stream at the auxiliary port so that it bends rightwardly. This enables to promote the supply of the air to the vicinity of a side wall and corner parts where a high level CO is present and to reduce a quantity of CO produced.
摘要翻译：目的：为了减少在侧壁附近和角部附近产生的高水平的CO的量，通过形成小辅助OA口的方法位于比最外面的燃烧器排更靠近侧壁的位置，以及燃烧机构中的OA端口呈可转动圆形的形式。构成：与其他OA口23的旋转方向不同的小型辅助OA口24在炉的侧壁附近的两个角处平行地形成。也就是说，在常规OA口中的燃烧器部分的空气流和空气流中产生顺时针旋转流，使得气流向左弯曲，同时在辅助口处的空气流中产生逆时针旋转流，使得它向右弯曲。这能够促进空气供应到侧壁附近和存在高水平CO的角部，并且减少产生的CO的量。

摘要： PURPOSE:To safely discharge the residual LPG from a system by a method wherein residual LPG in a piping is extracted from the piping, then evaporated, and incinerated at a burner, in a system for transporting LPG as a liquid and burning it. CONSTITUTION:Liquid LPG coming out of an LPG storage tank 1 is fed under pressure to a burner 9 by a pump 3, and sprayed and burnt. The combustion is stopped by fully colsing an inlet valve 8, when LPG is left in pipes 2, 12. For treating the residual LPG, first an N2 purge valve 20 is fully closed and valves 11, 13, 4 are fully closed. Then an N2 purge valve 19 and a vent valve 14 are opened, and N2 gas is fed under pressure from a pipe 18 into the pipe 2. By this, the residual LPG is flowed through a valve 7 and pipes 12, 15 into an evaporator 21, where it is heated by hot water 31 to evaporate. The evaporated LPG is fed to a burner 26 through a superheater 24, and incinerated.

摘要： PURPOSE:To positively detect the flames at a burner, by detecting the change of the electric resistance of a flame-resisting wire by means of a detecting circuit. CONSTITUTION:When a burner 1 is not ignited, a bridge circuit 8 keeps equilibrium because there is no flame, and output is not emitted to output terminals 13. When the burner 1 is ignited, the temperature of a fire-proof resistance wire 6 rises by heat energy radiated from flames 5, and the electric resistance is enlarged in response to the rise. Thus, the equilibrium of the bridge circuit 8 is broken and fixed output voltage appears between the output terminals 13. Flame detecting signals can be obtained by amplifying and extracting the output voltage by means of a proper amplifier. Consequently, flames can positively be detected even if the flames are beforehand formed without regard to the change of a combustion condition, the change-over of fuel, etc.

摘要： PURPOSE:To control the viscosity of slurry in a rotating mill easily on line by receiving the slurry discharged from the mill into a tank and measuring its level charge rate. CONSTITUTION:Produced slurry 9 runs in a mill outlet grille plate 10 while maintaining an apparent gradient theta which corresponds to the viscosity of the slurry. When the slurry passes through the grille plate 10, it is sent to a screen 11 side with an apparent head H and flows down into a slurry tank 12 through a screen 11. theta and H are the values which are influenced by the viscosity of the slurry 9 in the mill. Therefore, the amount of slurry which flows down into a slurry tank 12 from the screen 11 per unit time, that is, the discharge rate of slurry from the mill changes depending upon the viscosity value of the slurry 9 in the mill. A momentary change in the discharge rate of the slurry can de detected by a differential pressure level detector 14 provided in the slurry tank 12. Subsequently, the state of a change in the viscosity of the slurry 9 in a tube mill 1 can be obtained.

摘要： PURPOSE:To permit the decompression with reduced noise without applying an extreme load onto the apparatus by arranging a member having at least a multihole part for fluid decompression into a valve apparatus body and adjusting the opened area of the multihole part. CONSTITUTION:High-pressure fluid flows into a fluid control part 6 from a valve box 3, and passes through a small hole 6c and further passes through a small hole 10a on a cage 10 and then flows outside. Since, in this case, the fluid is pressure-reduced in two stages in the valve body 6 and the cage 10, smooth decompression is permitted, and a part of the valve apparatus is prevented from being applied with a large load. When the valve body 6 lowers, a part of the opened port of the cage 10 is closed by the side wall of the piston part 6a of the valve body 6, and since the fluid passing part 6b lowers into a valve seat 8, the number of small holes is reduced, and the flow rate reduces.

摘要： PURPOSE:To control the production of CO of high level and to enable concentration of CO exhausted to be reduced on the whole, by positively feeding the air to the vicinity of the side wall of a furnace and promoting mixture. CONSTITUTION:Each burner 3 is provided with an air resister to regulate it so that the air is all revolved clockwise. Air ports 4, positioned right above the burner, are also regulated so that the air is revovled in the same direction. Further, auxiliary air ports 14 and 15 are formed closer to the opposite side walls 8 than the air ports on the side wall side, only the one air port 15 is caused to revolve counterclockwise or in the reverse direction to that of the other air port 14 positioned facing and opposite to the former air port so that all the air currents of the additional air ports turn toward the side wall 8. If the diameter of the additional air ports 14 and 15 are identical to or smaller than that of the air port 4, it can result in displaying the function thereof.
