Why lp heater have no qcnrv?
non-return valves of swing check type provided with a forced closing mechanism. They are installed in turbine extraction lines. The purpose of these valves is to prevent the back flow of heavy specific weight and low temperature steam to turbine during a turbine trip
What is a kick in drilling operation?
A kick in drilling operations refers to an uncontrolled influx of formation fluids, such as oil, gas, or water, into the wellbore during drilling. This can occur when the pressure in the formation exceeds the pressure exerted by the drilling mud, leading to potential blowouts if not managed promptly. Proper monitoring and control measures, such as using blowout preventers (BOPs), are essential to mitigate the risks associated with kicks. Effective response to a kick is crucial for the safety of personnel and equipment, as well as environmental protection.
How does the air move during daytime?
The air moves in the exact same manner regardless of the time of day. However, air near the ground in areas where the ground level consists of vastly different materials, typical airflow during night may differ from the typical daytime situation. For example, in a coastal region, land (rocks, sand) might meet the sea. During the day, the rocks heat up quicker than the large body of water, so the air starts to rise above the land, and the local air flow goes towards the coast. However, during the night, the shore cools but the sea maintains its temperature, causing the wind direction to change to a seabound breeze during the night. These conditions can be observed in nature, however, local climate, weather conditions, currents and conditions on the shore as well as in the water will affect this phenomenon.
What is an engineering problem?
The Mistakes done by engineers during there work which leads to some kind of damage to society is called engineering problem.
Which technical review is held during the Engineering and Manufacturing Development Phase to assess the final design after the build to baseline has been achieved?
Critical Design Review
What is mark 6 control system?
MARK6 is used for the protection of steam and gas turbine in electrical generators and process plant applications The main function of Mark6 turbine control system are: -speed control during turbine start up -automatic generator synchronization -turbine load control during normal operations on the grid -protection against turbine -protection against turbine over speed on the loss of land The mark6 system is available as a simplex control or a triple modular redundant (TMR) control with single or multiple racks, and local or remote I/O. The I/O interface is designed for direct interface to the sensors and actuators on the turbine, to eliminate the need for interposing instrumentation, and to avid reliability and maintenance issues associated with that instrument. NOTE : to obtain a highest reliability, MARK6 uses a TMR architecture with sophisticated signal voting techniques.
What is turbine barring system?
A turbine barring system is a mechanism used to rotate a gas or steam turbine slowly when it is not in operation. This slow rotation helps to evenly distribute temperature and prevent thermal stresses, thereby extending the life of the turbine components. The system typically engages the turbine shaft through a barring drive, allowing for maintenance and inspections while ensuring that the turbine remains in optimal condition. It is crucial for preparing turbines for startup and for maintaining their health during extended outages.
What is Pole discrepancy protection?
Pole discrepancy protection is a relay protection scheme used in power systems to detect discrepancies in the operating characteristics of protection relays during a fault condition. It helps to identify instances where different protection relays connected to the same power system asset (such as a transformer or line) are not tripping in coordination, which can cause delays or maloperation in fault clearing. The protection scheme typically involves measuring the time delay and coordination of the relays to ensure proper operation.
How can you measure axial displacement of turbine?
Axial displacement of a turbine can be measured using a non-contact displacement sensor, such as a laser displacement sensor or an eddy current sensor, which provides precise readings without interfering with the turbine's operation. Alternatively, dial gauges or linear variable differential transformers (LVDTs) can be used to measure the axial movement by directly contacting the turbine components. It's important to ensure that the sensors are properly calibrated and positioned to accurately capture the displacement during turbine operation. Regular monitoring helps in assessing the turbine's condition and preventing potential failures.
What is steam turbine Turbine Stress Evaluator?
The Turbine Stress Evaluator (TSE) calculates and monitors the operational heat stresses of the turbine during every operational phase. The goal is to achieve continuous optimization between material stresses on the turbine and flexibility in reacting to operational changes.
What is turbine drain valve?
When steam is introduced to a turbine during start up, drain valves are fully open. They drain to the condenser until the turbine reaches a certain load. Once that load is reached, the valves are closed and turbine runs normally.
Which is a correct statement of what occurs at a turbine during electricity?
At a turbine, mechanical energy from a rotating shaft is converted into electrical energy as the turbine blades spin within a magnetic field. This process induces current in the wires connected to the turbine, generating electricity.
Where can I go online to learn more about turbines and turbine parts?
The Pelton wheel in the turbine is most likely to break. This is because the part is used to protect the turbine during winter freeze-up and spring break-up,
When did tesla invent the tesla turbine?
The Tesla turbine was invented by Nikola Tesla in 1913. It was designed as a bladeless turbine that utilized the principle of boundary layer effect to achieve efficient fluid movement. Although it was patented in 1913, the turbine did not gain widespread commercial success during Tesla's lifetime.
What features should I look for in a hard shell suitcase to ensure durability and protection for my belongings during travel?
When choosing a hard shell suitcase for travel, look for features like impact-resistant materials, reinforced corners, secure locking mechanisms, and smooth-rolling wheels for durability and protection of your belongings.
Energy transformation that occur during the operation of wind turbine?
During the operation of a wind turbine, the wind spins the blades of the turbine. Therefore, the energy is transferred into the turbine, which generates electricity. A generator is a machine that produces electrical energy from mechanical energy. And so as a result, the wind energy turns into mechanical energy and turns into electric energy. Does that help?
Does hot rolling create greater drafts or does cold rolling?
Yes hot rolling create greater draft than cold rolling . This is because during hot rolling the material is hot due to which it is soft thereby making it easy for more draft
