Title: Steam turbine cogeneration plant
Inventor: ARONSON KONSTANTIN ERLENOVICH
IPC: F01K17/02
Filed: 2020-12-18
Granted: 2022-03-15
Abstract: FIELD: thermal power engineering. 
     SUBSTANCE: invention relates to thermal power engineering and can be used at thermal power plants for steam turbine heating plants (STHP), which use steam jet ejectors. The cogeneration steam turbine plant contains a steam turbine 1 with a turbine condenser 2 connected through a branch pipe, a steam extraction line made in the form of a steam pipeline connected to the general station steam collector 8. Steam to the main ejectors 6, 7 of the turbine and to the ejector 10 of the network water heaters, made of steam jet and connected in parallel to each other, is supplied from the general station steam collector 8 through the corresponding steam pipelines through the corresponding steam pipes. The ejector 10 of the network water heaters has a steam-air mixture compression ratio (SAM) of 2…3, which is less than the SAM compression ratio in the main ejectors 6, 7 of the turbine 25…30. Steam heaters 4 and 5 network water horizontal is supplied through line 17 from the selection of the steam turbine 1 through the appropriate pipe. SAM is cascaded from the network water heater 5 to the network water heater 4 along the line 16 for the removal of the steam-air mixture, and then it is sucked out of the network water heater 4 by the ejector 10 of the network water heaters along the steam-air mixture suction line 11. The steam condensate is cascaded from the condensate collector of the heater 5 of the network water to the condensate collector of the heater 4 of the network water. From the condenser 2 of the turbine, by means of a pump 3, the main condensate (MC) is fed through the coolers of the main ejectors 6, 7 of the turbine along the line 13 of the main condensate (MC). The steam condensate through the respective coolers of the main ejectors 6, 7 of the turbine is discharged into the condenser 2 of the turbine through lines 9 for the removal of steam condensate, and the air from the main ejectors 6, 7 of the turbine is discharged through line 14 into the atmosphere. The ejector 10 of the network water heaters through the cooler is connected to the line 13 of the main condensate behind the main ejectors 6, 7 of the turbine, and the condensate of its steam is supplied through the line 12 of the steam condensate outlet to the condensate collector of the first heater 4 of the network water, and from it the steam condensate of the ejector 10 of the network water heaters and steam condensate from the condensate collector of the first heating water heater 4 is fed into the main condensate line 13 after the ejector 10 of heating water heaters. 
     EFFECT: reduction of heat consumption for own needs of the heating plant and increase in the reliability of the operation of the air suction circuit from the network water heaters.

Abstract: A control system for a central lubrication system with an electrically operated lubrication pump for vehicles without their own power source, such as trailers, carriers for utility vehicle, etc., includes an electrical time-controlling device to activate the lubrication pump as a function of the operating time of the vehicle. Power is supplied to the time-controller device and the drive motor for the lubrication pump via the feed lines for the brake light. The time-controlling device has a sensor which detects motion of the vehicle or parts of the vehicle and generates a signal for a second timer during such motion. The second timer adds the durations of the signals sent from the sensor, compares the sum of the durations to a predefined pause time and, when the predefined pause time is exceeded, sends a signal to a third timer, which is thus enabled and in turn sends an enable signal for the activation of the drive motor of the lubrication pump during the next braking operation; the third timing signal adds the durations of successive braking operations during which the drive motor of the lubrication pump is activated, compares the sum of the durations with a predefined operating time and, upon reaching the predefined operating time, sends a signal to the second timer, whereby the enable signal sent from the second timer, and consequently also the enable signal for the activation of the drive motor of the lubrication pump, are cancelled.

Abstract: For winding and cross-cutting a web (11), use is made of a device having a first driving roller (21), which is mounted in pivotable supporting arms (22) and can be pressed against the outer circumference of the wound package (8) forming about a receiving roll (9). In a pivotable roller frame (1) is mounted a second driving roller (7) which can be brought into contact with a second receiving roll (9'), which is still to be wound. A group of deflecting rollers (14 to 17) is mounted in a common supporting structure, which, in turn, is mounted pivotably on the roller frame (1). Also arranged in the roller frame (1) are rollers (19) which can be pressed against one another of which at least one roller is driven. A cutting member (10) is arranged underneath said rollers (19) in the roller frame (1). The web (11) is so guided about the individual deflecting rollers (14 to 17) that the supporting structure (12) can be swivelled unimpeded together with said rollers into a position in which the web (11) loops round the receiving roll (9') still to be wound. The roller frame (1) and, in this, the supporting structure (12) can be swivelled in such a way that the deflecting rollers (14 to 17) are transferable into a position by means of which a part of the web (11) and the receiving roll (9') still to be wound form a gap (23) which narrows in the running direction of the web (11) and in the circumferential direction of the receiving roll (9'). This gap is situated underneath the two rollers (19) which can be pressed one on the other and the cutting point, situated below, for the web (11), so that the new web beginning is guided positively into the gap (23) without any other auxiliaries than the web (11) itself being necessary.
