Patent number: 6269299Abstract: The present invention pertains to a method/process and system for parameterizing, structuring and programming control and regulating systems for pieces of machinery, especially turbines and compressors as well as drive units thereof, wherein these are connected to a control and regulating system via feedbacks and control lines. These control lines transmit measured values from the piece of machinery to the control and regulating system via measuring transducers. These control lines transmit adjustment commands from the control and regulating system to actuating drives of the piece of machinery. A first or local programming device is connected to the control and regulating system via a programming line. A monitor is provided for displaying the operating data and programs, as well as a keyboard for entering control commands and programming instructions are connected to the said first programming device.Type: GrantFiled: July 28, 1997Date of Patent: July 31, 2001Assignee: GHH Borsig Turbomaschinen GmbHInventor: Wilfried Blotenberg

Patent number: 6226978Abstract: A hot gas-carrying gas collection pipe (1) of a gas turbine, which is arranged between the combustion chamber and the turbine blades. The gas collection pipe (1) has two inlet openings (2) for receiving the hot gas. The outlet comprises the flanges (5, 6), which are connected to the turbine. The material of the gas collection pipe (1) is a high-temperature- and corrosion-resistant base metal (9) with a high-temperature corrosion and oxidation coating (4) applied to both the inside and the outside of the base metal (9). In the area of the inner cone (13), an HTCO coating (4) is applied to the base metal (9) on one side and a thermal barrier coating (8) is applied on the opposite side.Type: GrantFiled: March 5, 1999Date of Patent: May 8, 2001Assignee: GHH Borsig Turbomaschinen GmbHInventors: Sharad Chandra, Berthold Ellermann, Heinz Gathmann, Werner Schnieders

Patent number: 6174131Abstract: A process gas compressor for the stepwise compression of process gases with increased percentage of hydrogen sulfide (H2S), with an H2S-uncritical area and an H2S-critical area, in the housing (5) of which impellers (3) and (2) with a direction of flow to the right (7) and, after cooling (6), impellers (2) with a direction of flow to the left (8) are arranged on a shaft (1), wherein the impellers (3) and (2) are provided with blade ends (4). The transition from the uncritical H2S area to the critical H2S area takes place after the outlet of the first or second larger impeller (3) on the shaft on the left. This is followed by another impeller (2) with a direction of flow to the right (7), which is already located in the critical H2S area. The precompressed process gas is subsequently sent to a cooler (6) before it enters the impellers (2) in the critical H2S area of the process gas compressor at the second gas inlet stage (8) and leaves it at the housing outlet (9).Type: GrantFiled: December 5, 1997Date of Patent: January 16, 2001Assignee: GHH BORSIG Turbomaschinen GmbHInventor: Gerd Janson

Patent number: 6171052Abstract: The present invention pertains to the cooling of a honeycomb seal (2), which is arranged in a carrier ring (4), with vertical (2.2) and horizontal (2.1) honeycomb openings. To achieve this, the support ring (4) of the honeycomb seal (2) is provided with cooling air grooves (5) and tangentially arranged cooling holes (6), so that the cooling air (7) is fed homogeneously from the outer annular chamber (8) to the honeycomb seal (2) and can escape via the open honeycomb structure (2.2). Intense cooling action of the honeycomb seal (2), which is subject to high thermal stress, is generated as a result. Furthermore, corrosive process gas is kept extensively away from the honeycomb seal (2). At the same time, the sealing effect of the rotor blade labyrinth seal is improved by the cooling air flow (7) and the rotor blade leak flow (11) crossing each other or being directed in opposite directions.Type: GrantFiled: April 16, 1999Date of Patent: January 9, 2001Assignee: GHH BORSIG Turbomaschinen GmbHInventors: Emil Aschenbruck, Markus Beukenberg

Patent number: 6164901Abstract: A process for operating multistage turbocompressors (2, 22, 42) with a plurality of controllers (15, 35, 55) which interact one with each other, in which each compressor stage has anti-surge control valves (5, 25, 45) of its own, which recycle into the suction lines (1, 21, 41) of their respective own compressor stage (2, 22, 42). The control is performed by flow computers (6,26,46) for calculating the suction flow and computers (7,27,47) for determining the minimum acceptable flow from the delivery head. A comparison unit (12, 32, 52) determines the difference between the set point (derived from delivery head) minus the actual value (flow) and whenever the actual value is too low compared with the set point, it brings about a gradual opening of the corresponding surge line control valves (5, 25 and 45) until the actual flow exactly corresponds to the flow set point, which depends on the particular delivery head.Type: GrantFiled: June 18, 1999Date of Patent: December 26, 2000Assignee: GHH Borsig Turbomaschinen GmbHInventor: Wilfried Blotenberg

Patent number: 6099198Abstract: A axially split casing with flange connection of two casing halves, wherein the casing upper part (1) is bolted to the casing lower part (2) with split line bolts (5) on the circumference of the axial split line flange (3). An axially divided casing extension (9), which is surrounded by a coaxially arranged axially unsplit ring (11) on the outer circumference, is arranged at one or both end faces (4) of the casing upper part (1) and the casing lower part (2) in the area of the casing axis (8). Wedge-shaped tensioning elements (14), which are tensioned by means of tension bolts (15) between surfaces (13) arranged in the ring (11) and countersurfaces (12) of the collar (10) of the casing extension (9), may be additionally arranged between surfaces (12, 13) arranged in the ring (11) and the collar (10) of the casing extension (9).Type: GrantFiled: June 23, 1998Date of Patent: August 8, 2000Assignee: GHH Borsig Turbomaschinen GmbHInventors: Joachim Kotzur, Alfred Schlemenat, Gerd-Ulrich Woelk

Patent number: 5960624Abstract: A process for regulating gas pressures of a regenerator with a gas expansion turbine in a flue gas line with a generator, wherein a process regulator opens the inlet valves of a gas expansion turbine and/or the bypass valves or throttles the bypass valves, doing so once with operation and once without operation of the gas expansion turbine. The process regulator is followed by a plurality of function generators, which preset the correcting variables for the downstream valves and in which a first function course of the function generators for operation of the gas expansion turbine and a second function course of the function generators for operation without gas expansion turbine are stored. A quick-acting valve of the inlet valves is acted upon by the speed regulator and it is active only at the time of the start-up of the gas expansion turbine until synchronization of the generator.Type: GrantFiled: May 30, 1997Date of Patent: October 5, 1999Assignee: GHH Borsig Turbomaschinen GmbHInventor: Wilfried Blotenberg

Piston rings (4a) are inserted in the upper part (1a) of the valve cone (1) sliding in the valve core upper part (3a), and piston rings (4b) are inserted in the lower part (1c) of the valve cone (1) sliding in the valve core lower part (3b). Clean water is used as the hydraulic fluid for the hydraulic drive attached to a connection spacer (15). At least one axial hole (2) is provided in the valve cone (1). With the upper part (3a) and the lower part (3b) of the valve core (3), the middle part (1b) of the valve cone forms an annular chamber (8), at which at least one suction channel (9) is arranged.Type: GrantFiled: September 8, 1997Date of Patent: August 10, 1999Assignee: GHH BORSIG Turbomaschinen GmbHInventor: Achim Zimmermann
