Why pelton turbine is called as impulse turbine?

Water is blasted at the buckets one by one or more jets mounted in the surroundings casing. Momentum is transferred from water to buckets and a torque is created, causing the wheel to rotate. That's why it is an impulse turbine.


Why the gas turbine needs 3 bucket stages only in 110MW TURBINE?

because all gas turbine has three stage buckets


How is a water wheel similar to a turbine in a hydroelectric power plant?

Both have blades or buckets.


How much does it cost to maintain a wind turbine?

The cost to maintain a wind turbine is estimated to be about 2% of the original investment per year. The cost of a wind turbine is $50,000.


What is governing of impulse turbine?

Basically governing of a turbine is controlling the speed of the turbine as the load keeps varying. The turbine needs to rotate at a constant speed. The governing of an impulse turbine is done by varying the jet of water that hits the buckets of the runner. This is done by using a spear arrangement in the pen stock. A pen stock is a type of pipe that provides the jet of water.

How does a turbo blower work?

turbo blower is an equipment where a turbine is attached with the blower part. steam enters through the turbine inlet and expands through the blades and goes to the outlet which helps the turbine shafts to rotate. this turbine shaft is attached with the shaft of blower that makes the blower rotating.

You can also get turbine parts here http://www.etspower.com/. You may have to search other sites if there is a specific part that you need.


What is turbine overspeed trip?

Typically two balls with springs holding them down, When the turbine spins too fast, the centrifugal force pushes the balls past the resistance of the springs at which point they hit a lever that stops steam/compressed gas flow to the turbine and the turbine shuts down. They are designed to keep the turbine from going so fast that it damages itself or the piece of equipment it is driving.


What will the electricity of a wind turbine cost?

This is a question of how much electrical energy you want to produce, against the cost of the equipment to produce it.

What is the function of a turbinate?

A turbine recovers energy from a fluid and converts it into mechanical power to drive another equipment (pump or compressor) or an alternator to produced electricity
