Title: Combined cycle power generation plant
Inventor: WAKAZONO OSAMU
IPC: F22B1/18
Filed: 1998-06-30
Granted: 2001-10-16
Abstract: While, in a prior art combined cycle power generation plant, steam which is needed at the time of restart of the plant after the plant has been once stopped must be supplied from outside auxiliary boiler which requires additional facilities resulting in complexity of plant, high cost, troublesome operation, etc., the present invention provides such a plant that is able to secure the steam needed at the time of restart of the plant and to shorten the time for the plant to reach a full load.            The combined cycle power generation plant comprises a waste heat recovery boiler (20) in which a stabilizing burner (25) is incorporated at an upstream position thereof.          The stabilizing burner is ignited during the time of start-up and speed lifting of gas turbine (11) so that steam generation at the waste heat recovery boiler is accelerated and the steam is made use of effectively for cooling of gas turbine and steam turbine, and further for gland steam and the like, and the time for the plant to reach a full load can be shortened.

Abstract: The operational performance of a fluid storage (12, 14, 16) and dispensing system (32, 34) is monitored by measurement apparatus which measures a volume associated with the system. A plurality of measurement data is collected from the measurement apparatus in a form readable by a computer (70, 90) and is stored in a compressed matrix format in a computer memory (74). The compressed matrix format is statistically analyzed to determine operational monitoring information regarding the system. The temperature of the fluid may be measured for calculating the volume (18) associated with the system. The operational performance and volume of the fluid storage system (12, 14, 16) may be precisely monitored without requiring presumptions as to the accuracy of the measurement apparatus.

Abstract: A metallurgical furnace unit (1) includes a cylindrical furnace body (2) whi ch is intended for rotation and/or tilting or like movement and is provided wit h at least one ring (7) mounted outside the furnace body (2) and functioning t o enable such movement to take place. Each ring (7) is spaced from the furnace  body (2) and connected to said body by means of a force transferring supporting-member (6) that extends in the longitudinal direction of the furnace unit (1). The supporting member (6) is adapted to prevent the transf er of furnace body movements caused by thermal expansion to the ring (7), and t o take-up external loads from the intrinsic weight of the furnace body and the  weight of the furnace charge. The invention is characterized in that the supporting member (6) has the form of a closed mantle which surrounds the furnace body (2) and which is connected to the furnace body (2) and to the ring (7) respectively by means of a flexible attachment that permits a given , limited change in the angle between the mantle (6) and the furnace body (2).  This angle may change as a result of movements of the furnace body (2) cause d by thermal expansion. As a result of the inventive design of these attachments, these movements are eliminated, in the absence of any significa nt curvature or other deformation of the actual mantle (6).

Abstract: A heat exchanger which is constructed such that combustion gas passages (4) for passage of combustion gas and air passages (5) for passages of air are arranged alternately, and the heat exchanger is cut at one end side thereof in an unequal angle configuration to form combustion gas passage inlets (11) and air passage outlets (16), and cut at the other end side thereof in an unequal angle configuration to form combustion gas passage outlets (12) and air passage inlets (15). The combustion gas passage inlets (11) and combustion gas passage outlets (12), through which a combustion gas having a larger volume flow rate passes, are formed on a long side of an angle, and the air passage inlets (15) and air passage outlets (16), through which an air having a smaller volume flow rate passes, are formed on a short side of an angle. Accordingly, it is possible to avoid an increase in pressure loss caused by a volume flow rate difference between a high temperature fluid and a low temperature fluid to reduce pressure loss in the entire heat exchanger.

Abstract: An echo canceler has its otherwise conventional tapped delay line basis functions augmented with at least one pair of basis functions realizing two quadrature responses of a complex pole. The frequency of this complex pole is selected as substantially equal to the frequency of the dominant pole of a highpass filter inserted into the echo path of the echo canceler, where the dominant pole is the pole closest to the unit circle. This echo canceler arrangement results in a substantial improvement in attainable echo-return-loss enhancement.
