What is condensing type turbine?

The condensing turbines take high pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. It is principally used when power must be generated with minimum steam consumption. These turbines are of bleed cum condensing type.

What is condensing and non-condensing turbine?

In turbine: Condensing and noncondensing turbines. Steam turbines are often divided into two types: condensing and noncondensing. In devices of the first type, steam is condensed at below atmospheric pressure so as to gain the maximum amount of energy from it. In noncondensing turbines, steam leaves the turbine at…

What is condensing steam turbine?

Condensing steam turbines are most commonly found in thermal power plants. This is achieved by passing the exhaust steam into a condenser (called a surface condenser), which condenses the exhaust steam from the low-pressure stages of the main turbine (decreases the temperature and pressure of exhausted steam).

How does a condenser turbine work?

In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. As that steam flows past a turbine’s spinning blades, the steam expands and cools.

What is a non-condensing turbine?

The non-condensing steam turbine uses high-pressure steam for the rotation of blades. The pressure of outlet steam depends on in the load, therefore, this turbine is also known as the back-pressure steam turbine. This low-pressure steam uses for processing and no steam is used for condensation.

What is the difference between back-pressure turbine and condensing turbine?

The mechanical energy is used to run an electric generator or mechanical equipment, such as pumps, fans, compressors etc. The outlet steam leaves the back pressure steam turbine at “overpressure” and then the steam returns to the plant for process steam application such as heating or drying purposes.

What is the difference between turbine and condenser?

In a condensing turbine, the heat that is not absorbed goes on to be condensed and represents wasted energy. In a non-condensing, (i.e., back-pressure) turbine, the heat that is not absorbed is used effectively in a downstream process.

What is non condensing turbine?

What are types of steam turbine?

The following types of steam turbines are available for private/thermal power generation plants.

• Small/Mid-sized Condensing Turbines.
• Extraction-condensing Turbines.
• Extraction Back-pressure Turbines.
• Mixed-pressure Turbines.
• Geared Turbines.
