摘要： PROBLEM TO BE SOLVED: To provide a device and method capable of removing a steam-oxidized scale with a good finish in a short time and capable of being easily applied in the periodic inspection and maintenance in an existing pipe. SOLUTION: An oxidized scale depositing in a pipe due to the circulation of high-temp. steam is removed as follows. Namely, an acidic chemical cleaning soln. 8 is sealed into a pipe 1 to be treated, a high-pressure liq. supply means 6 and a nozzle 2 for ejecting the liq. are inserted into the pipe, and the liq. is ejected into the chemical cleaning soln. at a high speed (jet 7) and collided with the scale.

摘要： PROBLEM TO BE SOLVED: To provide a cleaning device of a tube body being excellent in a cleaning efficiency, without making the device very large. SOLUTION: Acoustic wave generating devices 4 are so provided as to be opposed to hollow parts 3 formed between tube body groups 2 and the adjacent ones 2. The hollow parts 3 including the tube body groups 2 are put in a resonance mode by acoustic waves emitted from the acoustic wave generating devices 4 and thereby dust and the like sticking on tube bodies are removed.

摘要： PURPOSE:To facilitate adjustment of temperature of steam got out of a reheater and enable a high efficient operation of a plant to be carried out by a method wherein a secondary super heater and the reheater are arranged at a rear part of a furnace of a boiler and a flow passage bank for adjusting temperature of steam at an outlet port of the heater. CONSTITUTION:At a boiler in a thermoelectric power plant, main steam outputted from its secondary super heater is sent to high pressure turbine, steam of which work has been completed is returned back again to the boiler, reheated at the reheater 6 and 7, thereafter the steam is supplied to an intermediate pressure turbine and a low pressure turbine. In this case, the pipe arrangements of the reheater 6 and 7 are made such that a partition plate and a caster 53 are arranged in a main gas flow passage 51 and a bypassing flow passage 52 at about 25 to 50% height of the gas flow passage and then a cassette type buffle plate 54 acting as a flow passage bank which can be removably arranged is installed in the bypassing flow passage 52. In the case that some scales out of the pipes are dropped, a thermal collection of the secondary super heater is increased and then thermal collection at the reheater 6 and 7 is decreased, the fixing of the buffle plate 54 causes the coefficient of overall heat transmission of the reheater 6 and 7 to be increased and the temperature of steam at the outlet is increased.

摘要： PURPOSE:To provide a pitting corrosion prevention method for a reheater tube which can prevent or remarkably reduce, by inexpensive means, the pitting corrosion caused on its inner surface by dissolved oxygen included in condensate that is dewed when an intermediate loaded thermal power operation is performed. CONSTITUTION:In an intermediate loaded thermal power operation of steam power generation equipment, a unit inducing a boiler 30 as a steam generator for power generation, a high pressure turbine 7, a medium pressure turbine 18 and a low pressure turbine 19 is stopped. Afterward, dehumidified air is press-fed to an inlet of a reheater 14 while retention heat of the steam generator remains around the reheater 14 for forcibly purging steam having moisture inside the reheater tube.

摘要： PURPOSE:To achieve reduction of NOx and drastically reduce the quantity of discharge of unburned portion by forming a central air channel in a wind box which enters an air supply port that opens in the furnace wall of a combustion device and two concentric annular air channels and installing an air flow control device at the inlet of the air channel. CONSTITUTION:A the center of an air supplier 5 a cylindrical body 31 is arranged, and to the other end of the cylindrical body 31 a sleeve 33 for adjusting air volume and an operation handle 34 are attached to form a primary air channel 32. A cylindrical body 16 is supported by the cylindrical body 31 and is arranged on the same axis as that of the cylindrical body 31 in an annular shape. Between a support plate 17 of the cylindrical body 16 and a support end plate 18 supported by the cylindrical body 31 a secondary air channel 25 is formed, and at the inlet section of this channel 25 a plurality of guide vanes 19 are arranged radially with the central axis of the cylindrical body 31 and cylindrical body 16 as its center. Between the guide vane 19 and a support plate 23 installed in the radial direction of the cylindrical body 16 a tertiary air channel 24 is formed in an annular shape.
