Filed: 1989-12-01
Abstract: PURPOSE:To improve the controllability of a power plant during its transition time so as to carry out stable operation of the plant by providing a function generator which sets the set value of gas pressure according to power output or its corresponding value. CONSTITUTION:The load controller 18 of a coal gasifying combined power plant controllers a gasifying furnace controller 20 and a gas turbine controller 21 correspondingly to an aimed value 10 of output so that power output follows the aimed value 19 of output, and also that gas pressure is kept at a set value. The load controller 18 has a function generator which sets the set value of gas pressure higher than the aimed value when the power output is large, and lower when the power output is small. The maximum value of pressure fluctuations caused by changes in the load of the plant is thereby made smaller and the minimum value larger, and this reduces pressure fluctuations to within the range of normal operation. Also, the response delay of power output is improved and fluctuations in the amount of slurry supplied to a gasifying furnace 3 are reduced.

IPC: E21D9/06
Filed: 1992-10-29
Abstract: PURPOSE:To provide an automatic measuring method by which accumulation of errors is not brought about and the displacing work is simple and hence, can be finished in a short time and further the position of a shielding machine can be automatically measured in a straight or curved position. CONSTITUTION:The position of camera type detectors 1a, 1b is previously calculated as a basic point. The position of a camera type detector 1c connected to the camera type detector 1b is obtained from the length of a connection rod 25A and an angle theta3. A target 29 of the shielding machine 27 is picked-up by the camera type detector to obtain angles theta1, theta2. Since the length of the connection rod is known, when the angles theta1, theta2 are measured, the triangle formed by the camera type detector and the target is decided. Since the position of camera type detector is previously known, the position of shielding machine can be measured. When the target can not be sighted by the camera type detector 1a, the target is caught by use of the detectors 1b, 1c to measure the position of the shielding machine. The camera type detector 1a and the connection rod 25A are removed from the detector 1b and jointed to the detector 1c. The above action is repeated to displace the detectors in order to measure the position of shielding machine 27.
