摘要： PURPOSE:To obtain a flame monitoring apparatus which can separate a light signal into two or more optical paths without breaking the wavelength characteristic of the light signal while holding the loss at a photo branching part to be minimum. CONSTITUTION:In a flame monitoring apparatus (flame detecting apparatus 47, flame diagnosing apparatus 48), a signal from a flame 42 is guided to a plurality of photoelectric conversion parts 49, 50 through an optical fiber 44. The core diameter of an optical fiber 46 at the side of the photoelectric conversion parts 49, 50 is made smaller than that of the optical fiber 44 at the side of the flame 42. The optical fiber 46 has a plurality of core parts. Part of the core parts are connected to the photoelectric conversion part 49, and the remaining ones are connected to the photoelectric conversion part 50.

摘要： PURPOSE:To obtain a fire detector capable of working with an enhanced accuracy by providing a judgment unit to check a fire detector for normality and do judgment on ignition and extinguishment by comparing an output detected from a fire with a preliminarily set output value from a normally functioning fire detector and with thresholds for judgement as ignition and extinguishment. CONSTITUTION:The light emitted by a flame 17 from a burner 2 in a combustion furnace 1 is transmitted to a photoelectric conversion unit 7 through an optical fiber head 3 and an optical fiber-for-relay 6, and then converted to an electrical signal, out of which only an AC component is extracted. From the electric signal only specific frequency band components are extracted at a band-pass filter 8; then conversion to DC occurs at a rectification 9 to produce a fire detection signal E. On the other hand, fire detection signals under normal function of the detective device are preliminarily stored in a memory unit, setting E1 as the lowest value, E2 as the highest value, and Eoff as a threshold for judgment as extinguished. For the judgment, E is compared with E1, E2, and Eoff by a judgment unit 12. In the case of E

摘要： PURPOSE:To contrive the saving of fuel consumption by providing a water cooling wall converting feed water into vapour for the combustor of a gas turbine. CONSTITUTION:A water cooling wall converting feed water 59 into vapour for the combustor (pressurized combustion boiler) 50 is provided for a gas turbine generating system. High pressure saturated vapour 53 generated within an exhaust heat boiler 16 and vapour generated by the combustor 50 are led to a super heater 51 so as to be fed to a high pressure steam turbine 45. Thus, since the water cooling wall is provided in the combustor 50, combustion gas can be lowered in temperature down to the heat proof limit of a gas turbine, the quantity of air to be fed to the combustor can thereby be reduced. This constitution thereby enables the saving of fuel consumption.

摘要： PURPOSE:To increase heat efficiency of a complex power generating system by extracting CO from a forming gas by a CO absorbing unit, and using the extracted CO as fuel gas in a fuel cell. CONSTITUTION:A forming gas produced in a gasifying furnace 26 performs heat exchange with water and steam in a waste heat boiler, and sulfur oxide in the gas is removed in a desulfurizer 12, and CO in the forming gas is separated in a CO absorbing unit 101, and the residual gas is exhausted from the chimny 15 to the atmosphere. In the CO absorbing unit 101, CO in the forming gas is absorbed in a fuel electrode solution 104 having monovalent copper. The absorbed CO forms a carbonyl complex to activate CO electrochemically and is consumed as a fuel for a fuel cell 103.

摘要： PURPOSE:To reduce installation cost and operation cost by providing >=2 circulation tank 5 in a desalting chamber to enable changeover operation at the stage of actuation of an electrodialytic cell, a stage for water discharge and supply alternately by a changeover valve provided to a circulation system in the desalting chamber. CONSTITUTION:Supply of raw water 12 to a tnak A is commenced by opening a raw water feed valve 34. After the water level is detected to have reached high level by a water gauge A44, a raw water feed valve A is closed and the operation is held in the waiting state until dialysis of raw water 39 in the tank B31 is completed. When the concn. of salt attains specified concn. by the dialysis, the passage of flow is changed again by an outlet changeover valve 32 and a return changeover valve 33 of a salt water circulation tank so as to flow the raw water 38 in the tank A through the passage. The dialysis of the raw water 38 in the tank A 30 is thus commenced again, and the process is transferred to the dialysis process of the raw water 39 in the tank B 31 when the dialysis of the raw water 38 is finished. By repeating this procedure, operation of the electrodialysis cell is continued without suspending actuation of the cell.

摘要： PURPOSE:To enable the detection simply varying the view by inserting an optical fiber protective tube having an optical fiber inserted thereinto with the tip thereof bent previously into a fire detection nozzle to rotate the optical fiber protective tube from outside. CONSTITUTION:A protective tube 9 having an optical fiber 8 inserted thereinto is previously bent at the tip 10 thereof and an optical fiber light receiving section 4 is fixed with a fiber fastener 11. The protective tube 9 is inserted into and positioned in a fire detecting nozzle 7 of a boiler wall 12 and is rotated in the nozzle 7 by operating it from outside a boiler or the like as required to move the view of the optical fiber light receiving section 4 in a doughnut. Thus, a far view 16 can be captured simply from the view 15 close to a burner 14.

摘要： PURPOSE: To enhance the freedom of the selection of the stopping time of operation as well as increase the safeness of cooler for cement clinker, etc., by using a system in which the evaporating portions of a large number of heat pipes are positioned in the cooling chamber of high-temperature solids, and the condensing portions are also in the refrigerant flow outside the cooler.
CONSTITUTION: The evaporating portions 18 of each heat pipe 15 are heated by the radiant heat of cement clinker 8, whereby the heat pipe 15 is operated to transfer heat to the condensing portions 19 of the heat pipe 15. Since evaporating pipes 14 inserted with the condensing portions 19 are filled up with cooling water through a water supply pipe 1, heat is transferred to the cooling water 14 in the condensing portions 19 of the heat pipe 15, and steam is collected in a pipe 12 for removal. Thus, even when one of the heat pipes is broken, safety against the fear of explosion is raised because the amount of heat medium is less and therefore, the selectivity of the stopping time of operation is enhanced.
