摘要： A heavy oil emulsified fuel evaporator system is provided in which a heavy oil emulsified fuel, after being preheated at a preheater, flows into an evaporator to be heated and then to a separator for separation of its water content. The water content, after being separated, is used as a preheating source medium for said preheater, wherein water content separation at a predetermined level is enabled irrespective of load change in a heavy oil fuel combustion equipment, and no light oil content is discharged together with the separated water content. Heavy oil emulsified fuel 11a is preheated at a preheater 13, is heated at an evaporator 14 and flows into a separator 15 to be separated of its water content. Water content, after being separated, is sent via a piping 15a to be used as the preheating source medium for the preheater 13. Inlet temperature of the evaporator 14 is maintained constant, and pressure in the piping 15a for leading the preheating source medium into the preheater 13 is also maintained constant. Further, temperature difference of outlet temperature relative to the inlet temperature of the evaporator 14 is maintained constant. Thereby, the water content in the heavy oil fuel coming out of the separator 15 can be maintained at a predetermined value.

摘要： A heavy oil emulsified fuel combustion apparatus is provided in which steam bubbles generated in the pressure reduction operation for dewatering a heavy oil emulsified fuel before combustion are prevented from mixing into a dewatered heavy oil side resulting in lowering of a dewatering efficiency.In a heavy oil emulsified fuel combustion boiler, a heavy oil emulsified fuel 101 is heated by a heater 110 and dewatered by a flusher 120 and then introduced into a boiler 10 for combustion, and water 152 obtained by the dewatering is sent to a water utilizing system of the boiler. The heavy oil emulsified fuel 102 is heated in a high pressure and then introduced into a pressure reducing device 200 to be applied by a pressure reduction by multi-stage orifices 201 for dewatering. The pressure reduction is done with a pressure reduction per stage of 1 to 3 ata.

摘要： This invention relates to a method for decreasing sulfuric acid and sulfuric anhydride present in combustion exhaust gas which comprises adding an SO3-decreasing agent (hydrogen gas) to combustion exhaust gas and thereby reducing sulfuric acid (H2SO4) and sulfuric anhydride (SO3) present in the combustion exhaust gas, as well as a combustion exhaust gas flow system therefor. Thus, this invention provides a method for decreasing sulfuric acid and sulfuric anhydride present in combustion gas which can prevent the occurrence of troubles (e.g., low-temperature corrosion and ash deposition) arising from H2SO4 and S3 contained in combustion gas.

摘要： A horizontal mill for ultra-fine pulverization which has enhanced pulverization characteristics and reduced power consumption while suppressing damage or wear of pulverizing media. The pulverizing media (balls) are provided in a pulverizing chamber defined by a space between an inner cylinder and an outer cylinder which are rotated relative to each other. Large diameter pulverizing media are used and the rotational speed is kept at a low level, which is opposite to the conventional theory of using small diameter media and high rotational speeds. Since the rotational speed is low, the corresponding wear of the pulverizing media is reduced. The degradation in pulverizing performance due to the low rotational speed may be recovered by using large diameter pulverizing media. Also, the dimensional ratio between the inner and outer cylinders, the interval between the inner and outer sleeves, and the axial interval between agitating vanes are suitably selected to enhance the mill performance.

摘要翻译： 一种用于超细粉碎的卧式磨机，其具有增强的粉碎特性和降低的功率消耗，同时抑制粉碎介质的损坏或磨损。 粉碎介质（球）设置在由相对于彼此旋转的内筒和外筒之间的空间限定的粉碎室中。 使用大直径的粉碎介质并且转速保持在低水平，这与使用小直径介质和高转速的常规理论相反。 由于转速低，粉碎介质的相应磨损减小。 通过使用大直径的粉碎介质可以回收由于低转速引起的粉碎性能的劣化。 此外，适当地选择内筒和外筒之间的尺寸比，内套筒和外套筒之间的间隔以及搅拌叶片之间的轴向间隔，以提高轧机性能。

摘要： A plurality of current transformers connected in series provide secondary winding sides respectively connected to lamps. A constant-current source is provided to supply constant current to these lamps. Each lamp is connected to the corresponding terminal unit including a short-circuit switch for short-circuiting the secondary winding side of the transformer when the lamp is disconnected. A master station issues a request for detecting a disconnected lamp or checking whether or not failure occurs in the terminal unit to each terminal unit in the form of an instant power interruption. Each terminal unit has a proper identification time assigned thereto. In response to the request issued by the master station in the form of an instant power interruption, after the proper identification time for each terminal unit, the relevant terminal unit serves to turn off a short-circuit switch for opening the secondary winding side of the transformer for a predetermined time or, during the proper identification time, the terminal unit serves to control the short-circuit switch on and off according to a predetermined code to respond to the request issued by the master station. In the master station, the constant-current source reads the information from each terminal unit based on the waveform change of an output current and output voltage of the constant-current source so as to determine whether or not each lamp is disconnected, where the disconnected lamp is located, whether or not each terminal unit fails, and where the failed terminal unit is located.
