Steam Turbines – Powering up the world

Steam turbines are not new as they are found everywhere and are largely used to rotate huge power generators that produce electricity. Since their invention, they have become the most rugged, reliable and versatile drivers in the industry. Their primary motive is to convert thermal energy into mechanical energy by using turbine blades to make the rotor rotate. With hundreds of intricate elements existing in a steam turbine, it is no less than a miracle to run these massive machines.

Depending on the power requirement, technical specifications and allocated budget, there are different types and capacities of steam turbines. These powerful workhorses deliver tremendous value and performance in a wide range of drive and power generation applications, around the clock, in the most extreme conditions.

With world demanding more and more power to meet its relentless needs, there is a huge onus on steam turbines to become more reliable, more capable, and more effective. There is a complicated process involved to optimally utilize the steam power which give rise to two primary turbine designs – impulse and reaction turbines.

 

 

In an impulse turbine, steam nozzles focus the steam towards the rotors that encompass concave panels known as buckets. The nozzles are able to project a jet of steam that spins the rotor at a loss of nearly 10 per cent energy. Based on the change of position for the jets, they can increase or decrease the rate of rotor spin.

On the other hand, a reaction turbine works differently from an impulse turbine. The steam nozzles are attached to the rotor blades on opposite sides. The nozzles are positioned in such a way that when they project jets of stream, they spin the rotors that keep rotating as long as steam is being ejected. These rotors can attain high speeds because the nozzle designs focus the steam into a thin stream, although the early warm up period may take few moments.

Whatever the power requirements are, it is necessary to consult a renowned steam turbines manufacturer. This is because a good firm is capable of providing end-to-end support to the clients from determining the right type of turbine to its installation to its maintenance. As these systems require careful & high-end technical supervision, the entire process should be managed with high levels of precision. In addition, recent innovations have resulted in much more energy-efficient steam turbine solutions that only a leading steam turbine expert can understand the implement.
