A dark chamber is adapted to accommodate smoke particles. A photo emitter and a photo detector are disposed in the dark chamber. In a first region, a region where light emitted from the photo emitter passes and a region where the photo detector is capable of detecting light are overlapped, so that light emitted from the photo emitter and scattered by the smoke particles is detected by the photo detector. A photo converger converges light passed through the first region at a second region where is an outside of the first region.

摘要:
A reheat steam turbine power plant having a boiler with a superheater and reheater disposed therein, a high pressure steam turbine, an intermediate pressure steam turbine, a low pressure turbine, and a condenser condensing a steam exhausted through the low pressure turbine to a condensate. A turbine bypass pipe is provided with a bypass valve. A branch pipe branches off a cold reheater pipe between the check valve and the reheater is connected to the condenser for introducing steam flowing through the turbine bypass pipe. A control valve is arranged in the branch pipe and a controller controls the bypass valve and the control valve. When the turbine bypass line is operational in one of a start-up or an auxiliary operation of the power plant, the control valve and the bypass valve are controlled by the controller so that the quantity of reheat steam introduced into the reheater is controlled and excess or surplus steam is discharged to the condenser through the branch pipe.
摘要:
A side stream type condenser which has a first hot well for condensing steam exhausted from a turbine and storing the condensed water and a second hot well for storing the purified condensed water to prepare for water feed to a main system includes a partition plate for defining the two hot wells. The partition plate is formed with a weir portion so that part of the condensed water in the second hot well may overflow to keep a fixed water level. The weir portion is constructed in the shape of a labyrinth and is formed with a passage normally filled up with the condensed water, and a space in the upper part of the second hot well communicates with the upper space of the first hot well through this passage only. The condensed water in the first hot well is fed to a purifying system disposed outside, and is purified therein. It is thereafter fed to the second hot well when the main system requires the feed water and to the first hot well when not, through pipe means constructed so as to feed the water selectively to the first hot well and the second hot well. The water level of the first hot well is controlled by causing the condensed water to overflow from the weir portion. On the other hand, the water level of the second hot well is controlled in such a way that the actual water level is detected by a water level gauge disposed in the second hot well, that the quantities of water in an inlet and outlet of a tank for storing the feed water of the main system are controlled in accordance with the detected water level, and that the feed water of the tank is caused to flow into the first hot well.
