Automatic Extraction Non-Condensing Turbines (AENTs) are a type of steam turbine that can extract steam at one or more intermediate pressure levels. This extracted steam can then be used for process heating, cooling, or other purposes. The AENT then exhausts the remaining steam at a pressure above atmospheric pressure.

Here are some of the key technical details of AENTs:

Steam pressure and temperature: AENTs can operate on a wide range of steam pressures and temperatures. The specific steam conditions will depend on the design of the turbine and the application.
Extraction pressure: The extraction pressure of an AENT can be controlled to meet the specific needs of the application. This allows the AENT to provide the optimal amount of steam for process heating, cooling, or other purposes.
Exhaust pressure: The exhaust pressure of an AENT is typically at or above atmospheric pressure. This is because the AENT does not condense the remaining steam after it has passed through the turbine.
Speed: AENTs can operate at a variety of speeds. The specific speed will depend on the design of the turbine and the application.
Power output: AENTs can generate a wide range of power outputs, from a few hundred kilowatts to several hundred megawatts. The specific power output will depend on the size and design of the turbine, as well as the steam conditions.

AENTs are complex machines, and their design can vary depending on the specific application. However, the basic technical details described above are common to all AENTs.

Here are some additional technical details about AENTs:

Extraction valves: AENTs use extraction valves to control the amount of steam that is extracted from the turbine. These valves are typically controlled automatically by a computer system.
Governors: AENTs use governors to control their speed and power output. Governors are typically controlled automatically by a computer system.

AENTs are a versatile and efficient way to generate electricity and process heat. They are used in a wide range of applications, including:

Combined heat and power (CHP) systems
Industrial process heating
District heating
Power generation

If you are considering using an AENT in your application, it is important to work with a qualified engineer to select the right turbine for your needs.

Application Areas

Automatic Extraction Non-Condensing Turbines (AENTs) are used in a wide range of applications, including:

Combined heat and power (CHP) systems: AENTs are commonly used in CHP systems to generate electricity and process heat from a single fuel source. This can significantly improve the overall efficiency of the energy conversion process.
Industrial process heating: AENTs are also used in a variety of industrial processes to provide steam for heating, drying, curing, and distillation.
District heating: AENTs are sometimes used in district heating systems to generate steam that is then distributed to buildings and other facilities for heating and hot water.
Power generation: AENTs can also be used to generate electricity on a standalone basis. However, they are typically less efficient than condensing turbines for this application.

Here are some specific examples of how AENTs are being used today:
