What is the difference between a pulse system and a constant pressure turbocharger?
Types of turbochargers Turbochargers are of two types and they are pulse and constant pressure type turbocharger. Pulse type turbocharger: In pulse type turbocharger, the exhaust gas directly enters the turbine side and drives the turbine with the exhaust gas energy. The connection from the exhaust side of an engine is directly connected to the turbine side of a turbo charger. The pipe connections from the exhaust gas towards the turbine side are generally small in length and exhaust grouping is provided to prevent the blowback of gases from one cylinder to another. Constant pressure type turbocharger: In constant pressure type turbocharger, the exhaust gases gets collected in a single exhaust gas reservoir, where the pressure is maintained constant so as to avoid any fluctuation in the exhaust gas energy pressure. The exhaust gas is introduced to the turbine side after maintaining the pressure inside the cylinder. Materials: Turbine and compressor blades: Steel or nickel alloy. Volute casing: cast iron Bearings: steel or gun metal.
What engines did the titanic use?
Two triple expansion steam engines and an exhaust turbine
What are the stages in steam turbine?
Classifications of steam turbines: According to Principle: 1. Impulse Type 2. Reaction Type. According to Application: 1. Condensing 2. Non-condensing
What is the difference between back pressure steam turbine and condensate steam turbine?
In a back pressure turbine all available energy from the inlet steam is NOT used to generate power; steam exhausts at a tangible pressure and is then used for, usually, heating or chemical processing. In a condensing turbine, all the inlet steam does mechanical work right down to the lowest pressureafter which it is condensed in a heat exchanger
Why does gas turbine trips on high exhaust tempr spread?
nozzle fouling, restricted cooling, component wear
What is vaccume breaker in steam turbine?
A vacuum breaker is a check valve installed on the exhaust casing of a turbine. It opens to prevent the collapse of the exhaust hood when the turbine cools and the condensing steam produces a vacuum.
What is difference bw condensing and non condensing steam turbines?
A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.
What are the different types of steam engines?
Depends on how you want to catigorize them ... mobile or stationary piston or turbine condensing or non-condensing and weither the power comes from the steam pressure or from the vacumm you get when you condence the steam.
What property of the exhaust gas is being used to turn the turbine that runs the compressor?
At exhaust valve opening, pressurised gas reduces pressure by moving across the turbine blades and out of the exhaust pipe, the momentum of the moving gas is tapped by the turbine blades producing torque on the turbine shaft.
Why vacuum is created in condenser on steam turbine?
Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.

Why water is cooled in a thermal power plant before reusing it?
The problem lies in the excess amount of heat in the water, and the ability to pump hot water. Hot water has a tendency to flash into steam if it is too hot and will damage pumps when it does this. More importantly for power plants, too much heat in the water prevents the condensers from condensing steam back into water, such that it will build up heat and backpressure in the exhaust hood of a turbine, reducing the amount of power the turbine can put out, as well as causing damage to the turbine blades, from moisture build up in the low pressure stages of the turbine. The vacuum created by condensing the steam keeps the steam in its vapor state in these stages.
Why you are maintain the vacuum in steam turbine explain me briefly?
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
What is a turbo exhaust?
It's a turbine mounted in the exhaust manifold to give more power and smoother running to the engine.
What is a a turbocharger?
is a centrifugal compressor powered by a turbine which is driven by an engine's exhaust gases.
How much steam is required to produce 5 MW power in steam turbine?
How much steam is required to produce 5 MW power in steam turbine?In fully condensing turbine we will need 20 TPH steam required to generate for 5MW
What is the drive of a turbo charger?
the exhaust spins a turbine to make it spin
