Which sea friend has the startup steps for a steam compressor?

1.3 Activation of the dry gas seal: 1.1.3.1 Medium-pressure nitrogen (pressure: 1.66 MPa, at room temperature, flow rate: 300 Nm3/h) is used as the source of gas for the primary seal. This gas enters the sealing control system via the G1 flange port; after being filtered by the high-pressure fine filter F1 (or F2), it passes through the pneumatic diaphragm control valve PDV-2581, where its pressure is adjusted based on the pressure in the secondary balance line PdICSA2581. Subsequently, it enters the primary seal chamber on the low-pressure side and then reaches the shaft-end seal via the flow orifice plate (Pdt2581). A flow stream enters the primary seal chamber on the high-pressure side through the flow rate orifice plates (FT2580, FT2581). 1.1.3.2 Normal-temperature, low-pressure nitrogen at 0.40 MPa (G) and 120 Nm3/h is used as the gas source for the secondary sealing and the rear isolation. This gas enters the sealing control system via the G2 flange port, is finely filtered through filter F3 (or F4), and then divided into four streams that supply the high-pressure and low-pressure secondary sealing chambers as well as the rear labyrinth sealing chamber. 1.1.4 Contact the control room to inform the circulating water team to carry out the preparatory work prior to starting up the circulating water system. 1.1.5 The ITCC and the on-site inspection valves are all in the closed state, except for those in the operational instrument air system and some valves that remain open under shutdown conditions. 1.1.6 After receiving notification from the control room, start up the circulating water system. 1.1.6.1 Open the main inlet and outlet valves for the circulating water in and out of the system. 1.1.6.2 Open the upper exhaust valves of the cylinder room, inter-stage coolers, condensers, and oil-water coolers; close these valves once no gas is more being emitted from them, and then open the inlet valves. 1.1.6.3 Open the circulating water inlet valve of the condenser, and open the exhaust valve at the top of the condenser. Once no air is discharged from the exhaust valve and water begins to flow out, close the exhaust valve, then open the circulating water outlet valve of the condenser. 1.1.7 Check that the oil level at the fuel station is normal, and verify that the oil temperature in the tank is normal (if the oil temperature is low, the electric heater can be activated in advance to raise the temperature). 1.1.8 Start oil pump No. 1 at the oil station, open the filling valve to fill the high-level oil tank, and close it once it is full. Check whether the oil pressure is normal; the initial oil pressure should be controlled at 1.1 MPa (G). Check the return flow in the lubricating oil return main pipe, and control the pressure in the oil supply main pipe at 0.3 MPa (G). 1.1.9 Check that all drains in front of the main steam line’s large steam valve are open. Adjust the valve to the appropriate opening based on the amount of soda being discharged. Open the bypass valve of the main steam valve; after bypassing is enabled, drain and warm pipes are installed in the pipeline. 1.1.10 Contact the main control room to supply deionized water to the turbine condenser; press the stop buttons for the two condenser pump motors on site to shut them down, and add deionized water to the condenser. Stop adding water once the liquid level in the condenser reaches the high-level alarm threshold. Slowly open the inlet valve and the outlet valve of the condensate pump. Open the inlet and outlet valves for the cooling water of the extraction turbine cooler. 1.1.11 Experiment on automatic start-up of the condensate pump: Reset the emergency stop button for Pump #1; start Pump #1, and switch Pump #1 to main operation mode in the control room. Pump No. 2 was put into service; the emergency stop button for its motor was reset, and the pump started automatically, resulting in operation of both pumps. Similarly, when pump 2’s motor is running and the emergency stop button for pump 1 is pressed, pump 2 is switched to main operation in the control room while pump 1 is set to standby mode; the emergency stop button for pump 1 is then reset, and pump 1 starts up automatically, resulting in both pumps operating. After the experiment is complete, allow the drain liquid to flow back to normal levels before shutting off the drain valve. Open the atmospheric safety valve and the water filling valve, and adjust the valve openings so that no large amount of water flows out from the exhaust port of the atmospheric safety valve. Stop pump #2 in the control room and designate pump #2 as the standby pump. 1.1.12 Dual-pump interconnection test of oil pump: Check that the emergency stop button of the #2 standby oil pump is reset, the control system is set to automatic mode, the #1 oil pump is set to manual mode, the oil pressure regulation bypass valve is opened; an alarm is triggered when the oil pressure drops below 0.15 MPa, and then the #2 oil pump starts up. Record the data, close the oil pressure regulation bypass valve, and restore the oil pressure to normal. Stop pump #1 and set it as the standby pump in automatic mode; set pump #2 in manual mode. Similarly, conduct the 1# automatic and 2# manual tests. 1.1.13 Oil pressure low shutdown test: 1.1.13.1 The control room checks, through the turbine main interlock diagram, whether the conditions for starting the turbine are met; if these conditions are not satisfied, the turbine is switched to bypass mode. 1.1.13.2 Notify the control room to press the “Request Interlock Activation (to DCS) button” for 2 seconds; once an interlock activation signal is generated by the ITCC, the ITCC operator supplies power to the solenoid valve of the quick-shut valve. In the control room, it was checked that the light of the quick-shut valve solenoid was on, indicating that the solenoid was powered. 1.1.13.3 Establish start oil pressure by turning the start handle to the right on-site. The left-hand start lever generates the quick-shut oil pressure, causing the quick-shut valve to open. 1.1.13.4 At the common oil station, close the shut-off valve for PCV2502 and observe the lubricating oil pressure. When PS2512, PS2513, and PS2514 trigger an alarm, record the data (the design value is 0.15 MPaG). When the quick-close valve is closed, record the data (the design value is 0.1 MPaG). 1.1.14 On-site shut-off and ITCC shutdown test: Establish the quick-shut oil pressure according to the steps in 1.1.13, open the quick-shut valve, then press the shutdown lever on-site to close the quick-shut valve. At the same time, establish the quick-shut oil pressure to activate the quick-shut valve. 1.1.15 Vacuum level test: 1.1.15.1 Verify that the condensate pump is operating properly. 1.1.15.2 Open the valve on the condensate tank of the seal gas control system, open the bypass valve of the control valve, and artificially disrupt the vacuum. Based on the exhaust condition from the seal gas outlet, set the pressure to 0.0004–0.0006 MPa and switch to automatic mode; observe the tracking behavior of the control valve until stability is achieved. 1.1.16 Contact the control room to activate the turning gear device; the specific procedure is as follows: 1.1.16.1 Check that the emergency stop button of the turning gear device has been reset. 1.1.16.2 Control room barring fault reset. 1.1.16.3 Observe that the cranking preparation light is on. 1.1.16.4 Press the start button of the barring device; the start light of the barring device will illuminate, and the device will begin to operate. 1.1.16.5 Open the steam valve of the extraction pump on site. 1.1.16.6 Open the extraction valve of the extraction pump and observe the on-site vacuum level. Observe the vacuum level displayed on the ITCC; once the alarm is cleared, record the data. 1.1.16.7 Shutdown the train system; open the quick-shut valve according to step (12). 1.1.16.8 Stop steam extraction and gradually reduce the vacuum level. The quick-close valve closes. 1.1.16.9 Restore extraction steam to restore normal vacuum level. 1.1.16.10 Adjust the water filling valve of the atmospheric safety valve on site to ensure that water flows out from the overflow port of the water seal. 1.1.17 Check that the ammonia compressor is in condition to start up. 1.1.17.1 Verify that the oil system, water system, and dry gas seal system are ready for operation, and that all valves function properly. 1.1.17.2 The control system is ready for operation, with all instruments providing normal and accurate readings. 1.1.17.3 Make preparations before starting the turbine. Get ready for the work of making the pipes hydrophobic and heating them. Steam is connected to the boundary area. 1.1.17.4 Open all pressure tapping valves and activate the on-site local instruments. 1.1.17.5 Open the secondary anti-surge valve of the compressor. 1.1.17.6 Close the ammonia inlet valve, close the drain valve of the compressor’s gas-liquid separator, and close the compressor outlet valve. 1.1.17.7 The ammonia compressor has been successfully purged with nitrogen. 1.2 Warm-up (1000 r.p.m): 1.2.1 Open the main steam valve bypass valve and the drain valves in the plant, then close them after draining the water. 1.2.2 Notify the control room to stop the barring gear, and verify on-site. ITCC: Check the turbine startup interlock diagram to confirm that the startup conditions are met. 1.2.3 Check the steam drainage condition, verify that the steam pressure and temperature in the inlet section are stable, ensure adequate pipe warming, contact the main control room to confirm a stable steam supply, and open the quick shut-off valve according to the steps in 5.1.1.12. 1.2.4 Inform the control room operator to press the start button on the governor panel. Press SPEED to switch to the conversion tracking interface, and observe that the rotation speed tracking on the panel remains stable. 1.3 Increase the speed to 2000 r.p.m. 1.3.1 The speed increase time is determined in accordance with the time specified by Hangqi’s speed increase platform (20 minutes) and the superheat of the steam (the temperature corresponding to the given pressure) (360°C at 2.5 MPaA). 1.3.2 If the warm-up time at 1000 r.p.m. has elapsed but the steam temperature is not sufficient, automatic speed increase can be stopped, the speed can be adjusted back to 1000 r.p.m., and low-speed warm-up can continue. When the speed-up conditions are met, manually increase the speed to 2000 r.p.m. 1.3.3 If there is sufficient warm-up time, the speed can be automatically increased to 2000 r.p.m. 1.3.4 Monitor the shaft temperature and vibration of the turbine, observe the exhaust condition at the seal air outlet, and supply seal air. 1.3.5 Monitor the liquid level in the turbine condenser; if it is high, appropriate drainage can be carried out. 1.3.6 Open the turbine cylinder drain. 1.3.7 Monitor cylinder temperature and main steam temperature and pressure (exhaust cylinder temperature
