摘要:
A boiling water nuclear power plant supplies steam from a reactor to high-pressure and low-pressure turbines. Feed water generated by condensing steam in a condenser is heated by low-pressure and high-pressure feed water heaters and supplied to the reactor. The steam discharged from the low-pressure turbine is compressed by a steam compressor and supplied to one of the low-pressure feed water heaters to heat feed water. The steam extracted from the low-pressure turbine is supplied to the low-pressure feed water heater. When power required for the steam compressor is Q1, heat energy supplied from the steam compressor is Q3, a coefficient of performance of the steam compressor is COP (=Q3/Q1), and a thermal efficiency of the boiling water nuclear power plant is η, the steam compression apparatus is connected to a position in a main steam system and to the feed water heater so as to satisfy COP−1/η>0.

A boiling water nuclear power plant supplies steam from a reactor to high-pressure and low-pressure turbines. Water (feed water) generated by condensing steam in a condenser is heated by low-pressure and high-pressure feed water heaters and supplied to the reactor.

The present invention relates to a display control apparatus and method, and a program which make it possible to prevent deterioration in image quality due to insufficient luminance of light from a backlight.A backlight luminance calculating section (121) finds the backlight luminance of light to be radiated by a backlight, on the basis of the image signal of a display image. A moving image determining section (122) determines whether or not the display image is a moving image on the basis of the image signal. A correction value calculating section (123) increases the last correction value by a predetermined value to obtain a new correction value when the display image is a moving image, and decreases the last correction value by a predetermined value to obtain a new correction value when the display image is a still image. An addition section (124) adds the correction value to the backlight luminance to correct the backlight luminance. The present invention can be applied to a liquid crystal display apparatus.

摘要:
In a method for producing gas turbine fuel through the step of modifying heavy fuel oil with the use of an asphaltene-insoluble solvent, the utilization factor of the heavy fuel oil usable as gas turbine fuel is increased by making asphaltene selectively removable. A solvent having a specific inductive capacity in the range of 1.4 to 2.0 is used as the asphaltene-insoluble solvent. In particular, water controlled in temperature and pressure so as to have a specific inductive capacity in the above range is used as the asphaltene-insoluble solvent. By using such a solvent, an asphaltene component contained in the heavy fuel oil can be selectively removed and power generation can be performed while utilizing 95% or more of the heavy fuel oil.
