What is the difference between impulse and reaction turbines?
What is the difference between the Impulse and Reaction Turbine? In an Impulse turbine, All hydraulic energy is converted into kinetic energy by a nozzle whereas In a Reaction turbine Only some amount of the available energy is converted into kinetic energy.
What is impulse steam turbine and reaction steam turbine?
Impulse Steam Turbine and Reaction Steam Turbine- Marine Machinery Details. This jet of steam is directed into the impulse blades and leaves in a different direction. The changing direction and therefore velocity produces an impulsive force which mainly acts in the direction of rotation of the turbine blades.
What are the two main types of steam turbine?
Two types of steam turbines must be considered, condensing and noncondensing.
What is the function of turbine?
A turbine is a device that harnesses the kinetic energy of some fluid – such as water, steam, air, or combustion gases – and turns this into the rotational motion of the device itself. These devices are generally used in electrical generation, engines, and propulsion systems and are classified as a type of engine.
What is the main function of steam?
Answer: The main function of steam is to transport materials to all parts of the plant.
What are two types of steaming?
There are also two kinds of steaming methods, which are “low pressure steaming,” or also known as “atmospheric,” and “high pressure steaming.” Low pressure steaming is a process where food could be steamed through neither an indirect nor a direct contact with the steam, while high pressure steaming is when foods are …
What is meant by quality of steam?
What is Steam Quality? Steam quality is the proportion of saturated steam (vapor) in a saturated condensate (liquid)/ steam (vapor) mixture. A steam quality of 0 indicates 100 % liquid, (condensate) while a steam quality of 100 indicates 100 % steam.
How can you tell quality of steam?
Steam quality is a measure of the amount of saturated steam that coexists with its condensate in a given system. Calculate it by dividing the mass of steam by the total mass of steam and condensate.
What is the quality of steam leaving the turbine?
Typically major steam turbine manufacturer recommends 90 to 95% Exit steam quality.
How do I improve steam quality?
Although steam quality standards vary by application, common challenges are faced and the steps to achieving sufficient quality are shared:
- measure steam usage and costs.
- manage the root issue (water quality)
- optimize the boiler system design.
- employ maintenance best practices.
