Types of Turbines

Manaf and Marzuki (2004) point out that the rotational speed of the pulse turbine is 30,000 rpm. The entire droplet is produced in a set of nozzles and produces very fast steam. In order to generate a frequency of 50 Hz for power generation purposes, the steam turbine must be operated at 3000 rpm (Manaf & Marzuki, 2004). The maximum speed of the steam is generated at the nozzle outlet and the maximum speed in the blade decreases with high withdrawal loss. For this reason, pulsed steam turbines are mainly used as auxiliary devices for exhaust gases elsewhere.

Different types of turbines include steam turbines, combustion (gas) turbines, water (hydraulic) turbines, and wind turbines. In steam turbines, hot water and steam are produced by burning fuel in a boiler or by using a heat exchanger to take in heat from, for example, a fluid heated by solar energy or geothermal energy. Steam drives the turbine and the turbine powers the generator. Fuels or energy sources for steam turbines include biomass, coal, geothermal energy, petroleum fuels, natural gas, nuclear energy and solar thermal energy. Most of the largest power plants in the US have steam turbines

There are two basic types of steam turbines - pulse turbines and reaction turbines; blades are designed to control the speed, direction and pressure as they pass through the turbine. The generator is connected to the turbine so that the generator operates according to the principle of magnetic induction and generates electricity when the turbine blade rotates. The way to search for power depends on how it is used. Steam is usually condensed in a condenser. Therefore, the boiler, the steam turbine, the generator and the condenser form the main components of the steam generator plant. It is also possible to operate a steam turbine without a condenser, but in the case of a turbine of the same size, it provides a relatively low output capacity.

The described turbine is a simple turbine, also known as a DeLaval turbine. Turbines of this type typically rotate at a very high speed and this high speed will produce centrifugal forces. Turbines are typically small in size and thus produce small outputs. For high speed rotation it is generally not possible to drive directly between the drive between the turbine disk and the external device. For this purpose, a reduction gearbox is installed between the turbine disk and the turbine of the external device.
