摘要： PURPOSE:To enable a leaking position of fluid to be estimated in a piping by means of a relatively simple equipment at a low cost, by obtaining a gradient of pressure corresponding to each flow of the fluid in the sending end and receiving end of a transport pipe. CONSTITUTION:The increase in a feed flow is measured by a flow meter FX1 upstream from a fluid leadking position, while the decrease in an accepted flow is measured downstream thereof by a flow meter FX2. If fluid is caused to leak, sending and receiving pressures P1, P2 change into new sending and receiving pressures P1', P2' while a flow of the fluid changes, and the gradient of pressure also changes in the length direction of a pipe line. When a straight line C of the pressure gradient is derawn starting from the sending pressure P1' after the fluid leakage, and similarly a straight line D of the pressure gradient is drawn, starting from the receiving pressure P2' the intersection X between these straight lines signifies a leaking point.

摘要： PURPOSE:To facilitate an easy control of a diagram, by showing the connecting relation among the elements within the diagram in the form of a matrix and at the same time showing the connecting contents among the elements in the form of a connecting code. CONSTITUTION:The connecting relation of a diagram is analyzed by a computer to produce a matrix as shown in the figure, and a control arithmetic is carried out based on the matrix. Thus an operator has not to have a concern in the matrix table. For instance, SIGMA of an element 8 in the figure is supplied through elements 7 and 13 for connection. When this relation is examined on the line of the element 8 on the matrix table, it is found that the columns 7 and 13 are set at 1 with other columns set at 0. In such way, the number of the element that has a connecting output is known by examining the matrix of each element number. For the contents of connection, DELTA(DLT) of the element 8 for example has the negative and positive connections from the elements 1 and 2 respectively. Thus the contents of connection is shown by the connecting matrix of the table by deciding a connecting code.

摘要： PURPOSE:To switch an L-shaped flow path in a three-way burner valve having an L-shaped ball for switching a flow path, by an actuator for controlling the angle of rotation of the ball. CONSTITUTION:A burner valve 1 is operated to correspond to a burner ignition position (a), a heavy oil replacement position (b) and a burner extinction position (c) depending upon the rotation position of a ball 12. While the burner is ignited, a piston of a burner operating cylinder 10 is located at the burner ignition position (a) and when the burner is extinguished, the piston is thrusted to the heavy oil replacement position (b). As this piston moving stroke corresponds to 790 deg. revolution of a ball valve, the interior of the ball is supplied with heavy oil and a burner nozzle is replaced with heavy oil. Subsequently, the piston is thrusted from the heavy oil replacement position (b) to the extinction position (c). When the piston is located at the extinction position (c), the interior of the ball is filled with heavy oil, which has no possibility of solidification unlike COM fuel (mixed fluid of heavy oil and pulverized coal).

摘要： PURPOSE:To eliminate the possibility of adherence and pile of COM fuel (mixed fluid of heavy oil and pulverized coal) in pipe arrangement of a burner valve device for COM fuel. CONSTITUTION:A burner valve 2 is a three-way valve having three joining ports. A ball 9 in the valve is provided with joining holes A, B and C. The opposed joining ports are used as COM and heavy oil joining ports, and the intermediate joining port is used as an outlet leading to a burner 8. When the burner is ignited, COM fuel flows from the hole C of an intermediate flow path through the hole B into the burner 8. When the burner 2 is extinguished, the ball 9 is rotated counter-clockwise from a position (a) by 90 deg.. At this time, the hole B is connected to the heavy oil joining port, the hole A in flow path being connected to the heavy oil joining port, the hole C being connected to the burner outlet. Accordingly, COM fuel in burner piping is pushed out to a burner nozzle by the heavy oil, and the piping is filled with heavy oil.

摘要： PURPOSE:To prevent the excessive rise in the temperature of steam and the rupture of a boiler tube, by controlling the heat value of input fuel depending on the flow rate of feed water to a boiler to keep the temperature of steam constant. CONSTITUTION:When an input heat value controller is in a state of equilibrium, the flow rate of feed water is equal to a command and corresponds to the input heat value. Because the input heat value is the product of the quantity of input coal with the output signal 6 of a temperature controller 6, the flow rate of feed water corresponds to the product of the quantity of input coal with the output signal of the temperature controller. Therefore, the excess or shortage of the quantity of input coal due to the trouble in the input heat value controller 10 or the wrong operation by an operator can be immediately detected by a comparator 11 which compares the flow rate of feed water with the input heat value. When the calorific power of coal changes, the flow rate of feed water varies slowly. At that time, the temperature controller compensates the increment or decrement corresponding to the variation. Thus, the variation is not detected by the comparator 11.

摘要： PURPOSE:To facilitate an easy correction, by drawing a diagram equal to a plan on a CRT screen, reading and analyzing the diagram through a CPU, converting the contents of analysis into a data to store it in such way executing a control operation. CONSTITUTION:An operator produces a diagram through an image memory 5 by means of a producing device 1 while looking at a CRT screen 9. In other words, an optional square is designated with a light pen, etc. among small divided ones of the screen 9 and the memory 5. Then the control arithmetic elements, an arrow mark, a connecting line, etc. are drawn into the designated square. After this plotting work, a CPU reads these factors into the memory 5 and an inputted screen display data 11 to control them in the form of a screen data. Such diagram is analyzed through the memory 5, the data 11 and a table 13 to be converted into a data table. The control arithmetic is performed by calling out a subroutine of a PI arithmetic if the individual element within the diagram is PI.

摘要： PURPOSE:To control a surface level of brine in a multistage flash desalinator with a high accuracy, by directly measuring a surface level of the brine in an evaporation chamber, and controlling the maximum temperature of the brine to maintain the surface level at a constant level. CONSTITUTION:A multistage flash desalinator is operated, while controlling a desalination amount. A surface level of brine in an evaporation chamber is directly measured, and the measured value LX1 is compared with a reference value S. In case where the deviation of the value LX1 from the reference value S exceeds an allowance, an insensitive zone setting device DB outputs a signal, and a PI controller generates a proportion plus integration control signal. This control signal is carried through a rate limit, a max-min limit and an automatic-mannual switching device HIA, and compared with a signal from a maximum brine temperature gennerator TE. According to this comparison, a valve TCV for controlling heated vapor to heat the brine is opened or closed to make the maximum brine temperature to the reference value. Thus, the surface level of the brine is controlled with a high accuracy.
