Identifying Diverse Types of Steam Turbines

The world heavily relies on various forms of energy to power industries, cities, homes, and everything in between. In particular, steam turbines have played a pivotal role in generating power for power plants, refineries, manufacturing facilities, and numerous other sectors. These remarkable machines harness the power of steam to convert thermal energy into mechanical energy, which is then used to generate electricity. 

Impulse Turbines

Widely used in applications where high speeds are required, impulse turbines are commonly found in small-scale power plants and other similar industrial processes. For starters, they are characterized by their utilization of high-velocity steam jets that drive turbine blades accompanying the system. Upon actuation, steam enters the turbine through a nozzle, which then directs the steam jets towards the turbine blades. From there, the high-velocity steam impacts the turbine blades, causing them to rotate.

Reaction Turbines

Unlike impulse turbines, reaction turbines use both the velocity and pressure of steam to drive turbine blades. As the steam expands throughout the turbine assembly when actuated, it slowly loses pressure through each stage. This gradual pressure drop imparts kinetic energy onto the blades, resulting in their rotation. Due to their ability to handle high flow rates while producing significant power outputs, reaction turbines are often employed in large-scale power plants.

Condensing Turbines

Frequently used in power plants where steam is exhausted at a low pressure and temperature, condensing turbines are designed to maximize energy conversion by utilizing both the kinetic and thermal energy of steam. After passing through the turbine, the steam is condensed back into water, which allows for its reuse in the boiler. Moreover, the condensation process helps extract additional energy from excess steam, making condensing turbines highly efficient.

Extraction Condensing Turbines

As a variation of condensing turbines, extraction condensing turbines also permit the extraction of steam at intermediate stages within their assembly. By enabling the utilization of steam at different pressure levels for multiple applications, these turbines offer both enhanced flexibility and efficiency. As a result, the extracted steam can be used for various processes, such as heating or driving auxiliary equipment.

Back Pressure Turbines

Back pressure turbines are usually seen in industrial applications where power and steam must reach a specific pressure and temperature. These turbines are designed to exhaust steam at a higher rating than atmospheric pressure, allowing for its utilization in various heavy-duty industrial processes. As such, back pressure turbines are found in refineries, chemical plants, and cogeneration systems to meet their specific energy and process requirements.

Reheat Turbines

By utilizing a reheating process, heat turbines are designed to increase the efficiency of power generation. For example, the process begins when steam passes through the initial stage of the turbine, where it is then reheated before entering subsequent stages. This reheating process ensures that oncoming steam maintains a high temperature throughout its expansion, improving overall efficiency.

Geothermal Turbines

As we make it to the end of our steam turbine list, we cannot go without mentioning geothermal turbines, which are specifically designed to harness the energy from geothermal sources where steam or hot water is naturally available. As a whole, these turbines are engineered to withstand the unique conditions of geothermal environments, those of which include high temperatures as well as any corrosive substances.

Wrapping Up

In conclusion, steam turbines are versatile machines that convert thermal energy into mechanical energy, enabling the generation of electricity in various settings. Each type of steam turbine has its own unique aspects and applications to cater to the diverse needs of different sectors and power generation systems.
