摘要： PURPOSE:To reduce the waste heat of condenser for thereby improving the heat efficiency of whole facility, by arranging such that substances of low boiling point evaporated through the waste heat of cooling water of condenser may be compressed and heated up by a compressor directly coupled with a turbine, in a regenerating cycle. CONSTITUTION:A power generating facility utilizes the steam of boiler 1 to rotate a turbine 2 for a power generation. Substances of low boiling point are caused to evaporate in an evaporator 8, utilizing the waste heat of cooling water which has its heat exchanged through a condenser 6. After being compressed and heated up in a compressor 9, these substances of low boiling point are guided into a fuel gas pre-heating device 10 for their heat exchange with a fuel gas. These substances of low boiling point having their heat exchanged are reduced in pressure and returned back to the evaporator 8. Thus, the waste heat of condenser can be reduced, while at the same time improving the heat efficiency of whole facility.

摘要： PURPOSE:To recover Ar in high purity and at low cost and to reduce the cost of molten steel treatment by using water freed of dissolved air as the water for cooling a condenser of an evacuation apparatus wherein Ar is separated and recovered from the waste gas of the vacuum degasing equipment, and circulated and reused. CONSTITUTION:An inert gas 5' such as Ar is blown into suction pipe 2-1 at the lower part of a vacuum vessel 1, and molten steel 4 in a ladle 3 is successively sucked and continuously degasified. In this case, the inside of the vessel 1 is kept at 1-100mm.Hg, and the recovery of Ar is improved by reducing the N2 content in the waste gas from the vacuum degasing equipment. Namely, water freed of dissolved air in an evacuation apparatus is used as the water for cooling the condenser of the evacuation apparatus in order to reduce the N2 content in the waste gas. Besides, the waste gas condensed with the dissolved air-free water is stored temporarily in a storage tank, and then Ar is separated in an AR separator. The recovered Ar is circulated and reused as the gas for circulating molten steel, cooling the O2 lance, and sealing.

摘要： PURPOSE:To make it possible to measure a flow rate highly accurately from the outside of a pipe, by controlling a heating body so that the external temperature of the pipe becomes a specified temperature, and computing the flow rate of a fluid in the pipe based on the amount of energy, which is consumed for the control of the heating body. CONSTITUTION:A heat insulating material 3 is provided on the outer surface of a pipe 1 so as to cover electric heating coils 2a and 2b. Heat generated by the coils 2a and 2b is not diffused to the outside. Temperature detector/ controllers 4a and 4b detect the heated temperatures of the coils 2a and 2b. When the temperatures are deviated from the temperatures specified by variable resistors 5a and 5b, compensating signals are outputted to the corresponding resistors 5a and 5b. The heating amounts of the coils 2a and 2b are adjusted and the surface temperature of the pipe 1 is controlled at a preset value. A wattmeter 6 is connected to the resistor 5a, and the power consumed by the coil 2a is measured. The value of the power consumption is converted into the flow rate by operating process.
