Inventor: TORIMITSU SHINICHI
IPC: F22D5/34
Filed: 1990-06-29
Abstract: PURPOSE:To make it possible raise pressure by a minimum required fuel by regulating the opening degrees of a feed water regulating valve and water drum blow valve in such a manner that the feed water temperature at the economizer outlet becomes lower than the saturated steam temperature obtained by operation from the boiler drum internal pressure. CONSTITUTION:Right after the start of pressure ascent of the internal pressure of a drum 1, the feed water flow rate is controlled by regulating the opening degree of a feed water regulating valve 3 by a signal of a drum water level regulator 10 so that a drum water level meter 16 shows the value set by a drum water level setting apparatus 9. Also, when an indicating value of a feed water thermometer at an economizer outlet 4 reaches a saturation temperature obtained by a pressure-saturation temperature converter 11 by a signal of a drum pressure gauge 5, the feed water flow rate is controlled automatically so that the indicating value of the feed water thermometer at the economizer outlet 4 does not exceed the saturation temperature, by regulating the opening degree of the feed water regulating valve 3 by passing through a high selector 13 by a signal of a feed water temperature regulator 12. By this method, the feed water flow rate can be kept at the minimum necessity, and the fuel required to raise pressure can be kept to the minimum.

Title: Surface inspection method and device
Inventor: KAMATA AKIRA
IPC: G01N21/892
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To reduce the inspection time of surface inspection and to improve inspection accuracy. SOLUTION: A web 2 is intermittently carried in a direction marked by an arrow X. When the transportation of the web 2 stops, a light projection part 17 and an image pick-up part 18 are moved in the width direction of the web 2. Since the light projection part 17 uses ring-shaped lamps 26a-26d for applying inspection light at various angles from the surrounding of the image pick-up position of an image pick-up part 18, defects with any reflection factor and directivity can be securely subjected to irregular reflection. Since the image pick-up part 18 uses a high-resolution line CCD 21, it can detect even a small defect that could not be detected by a conventional surface-inspecting device.
