I’m not an expert in equipment; could someone explain in simple terms what a compressor turbine is? In the feasibility study, it is noted next to high-pressure steam that “compressor turbine” is involved; I searched on Baidu for a long time, but I still find it a bit confusing.
I guess that compressor turbine is probably a steam turbine. A turbine is a rotary power machine that converts the energy of steam into mechanical work. Also known as a steam turbine. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors, and ship propellers. A turbine is an external combustion rotary machine capable of converting the thermal energy of steam into mechanical work. Once the steam from the boiler enters the turbine, it passes through a series of annularly arranged nozzles and blades, thereby converting the thermal energy of the steam into mechanical energy that drives the rotation of the turbine rotor. In a steam turbine, steam undergoes energy conversion in different ways, which results in turbines with various operating principles.
"In the feasibility study, “compressor turbine” is noted after high-pressure steam; from this statement, it can be inferred that it refers to a turbine. ——Turbomachinery is the transliteration of “turbine”; it refers to power-driven fluid machinery equipped with blades. A common feature of turbine machinery is that it has a rotor equipped with blades that rotate at high speeds. As fluid (gas or liquid) flows through the channels between these blades, a force interaction occurs between the blades and the fluid, thereby enabling energy conversion. Based on the direction of energy conversion, turbine machinery is divided into prime movers and driven machines. The prime mover converts the energy of the fluid (thermal energy, potential energy, or kinetic energy) into mechanical energy, which is then used to drive a generator or other driven devices through the main shaft. Prime movers include steam turbines, gas turbines, turboexpanders, hydroturbines, and wind turbines. The drive mechanism is driven by an electric motor or another prime mover, converting mechanical energy into the energy of the fluid, thereby increasing the pressure of the fluid. Examples of such motors include ventilators, turbine compressors, centrifugal pumps, and axial flow pumps. The motive force and the prime mover are basically identical in principle and structure, with only the working process being opposite. The working fluid in turbine machinery can be a gas, such as steam, gas, air, and other gases or gas mixtures, or it can be a liquid, such as water, oil, or other liquids. Turbomachinery is mainly divided into two types: axial flow and radial flow (centrifugal or radial). In axial flow machinery, the fluid flows in an axial direction ; In radial-flow machinery, the fluid flows primarily in a radial direction. There is also a diagonal-flow type of machine, in which the flow direction of the fluid lies between the two mentioned above.
Reply 1# tanana: Turbine is the English translation; in English it is called turbine
Siemens defines it as follows: An industrial turbine refers to a steam turbine! And the compressor is, well, a compressor! Hehe
A turbine compressor is a type of rotary bladed machine that uses the interaction between gas and blades to increase the pressure of the gas. And it relies on the diffuser to slow down the airflow and increase the pressure. Based on the direction of gas flow, they can be mainly classified into: 1. Centrifugal compressors; 2. Axial flow compressors; 3. Axial-flow and centrifugal combined compressors
A turbine is a machine that converts the energy contained in a fluid medium into mechanical work. Also known as a turbine or turbomachine. Turbine is the transliteration of the English word turbine, derived from the Latin word turbo, meaning a rotating object. Due to the varying operating conditions and media used, turbines come in a wide range of structural designs, yet their basic working principles remain similar. The main component of a turbine is the rotating element (rotor or impeller), which is mounted on the turbine shaft and has blades arranged evenly around the circumference. The energy possessed by the fluid is converted into kinetic energy as it flows through the nozzle; as the fluid passes over the rotor, it impacts the blades, causing the rotor to rotate and thereby driving the turbine shaft to spin. The turbine shaft drives other machinery directly or through a transmission mechanism to deliver mechanical work. Turbines can be classified according to the fluid medium they use into hydroturbines (used as a power source in hydropower stations), steam turbines (used in thermal power plants, ship propulsion, etc.), gas turbines (used as propulsion for jet engines and ships, as well as in power plants and small power stations for peak load handling), and air turbines (which can only be used for very small amounts of power). Turbine – As water flows from a reservoir at a higher elevation through a channel to a turbine located at a lower elevation, the potential energy of the water at the higher elevation is converted into kinetic energy, which drives the turbine to rotate. The tailwater flowing through the turbine moves along the channel. The only purpose of modern water turbines is to serve as a power source in hydroelectric stations, driving generators to produce electricity. Turbine -- its working medium is steam, which possesses thermal energy. The steam comes from boilers that burn fossil fuels, or from steam generators heated by nuclear power plants. The high-temperature, high-pressure steam generated by them is sent at high speed through nozzles to the steam turbine, driving the rotor to rotate and generate power. The steam flow rate is very high and the turbine rotor is small, so the rotational speed can reach 10,000 revolutions per minute. Turbines are primarily used in thermal power plants to drive generators to produce electricity ; It is also used in large ocean-going ships and submarines as the main engine to drive the propellers and propel the vessels. Gas turbine – along with the compressor and combustion chamber, it constitutes the three main components of a gas turbine engine. Air is fed into the compressor, where it is compressed to higher pressure and temperature to become compressed air. This compressed air then flows into the combustion chamber, where it mixes with fuel and burns, resulting in a high-temperature, high-pressure, high-speed gas stream. This gas stream enters the gas turbine, driving it to rotate and generating mechanical power through the turbine shaft. Gas turbines can rotate at speeds of tens of thousands of revolutions per minute. The most common application of modern gas turbines is as propulsion for jet aircraft. Some are used as power sources for ships, power plants, and small power stations for handling peak loads, and they also serve as the driving force for gas pumps used in the long-distance transportation of natural gas. Gas turbines used as power for locomotives and cars are still under development and testing. There is also a type of gas turbine used in rocket engines; it serves as the power source for the pumps that transport rocket propellants (fuel and oxidizer). A gas generator generates the high-temperature gases needed through chemical reactions, which then drive the turbine to rotate and thus operate the pumps. Additionally, there are turbines that use compressed air as the working medium to drive rotation; they can only be used for small amounts of power, and such turbines are known as air turbines.
