The boiler heated by the solar heat converts water to
superheated steam
. This steam is used to run the turbine which powers the generator. Steam leaves the turbine and becomes cooled to liquid state in the condenser. Then the liquid is pressurized by the pump and goes back to the boiler.
Why condenser is an important for engine?
A condenser is
designed to transfer heat from a working fluid
(e.g. water in a steam power plant) to a secondary fluid or the surrounding air. ... Condensers have two significant design advantages over other cooling technologies: Heat transfer by latent heat is much more efficient than heat transfer by sensible heat only.
Why do we use condenser?
The function of the condenser in a refrigeration system is
to transfer heat from the refrigerant to another medium
, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser.
Why do we use condenser in steam power plant?
The main purpose in steam power plant is
to generate maximum power at high efficiency
. The most effective way for reaching this aim is to use a condenser. Condensers increase the enthalpy drops and turbine work by lowering the turbine outlet pressure. The lower the pressure, the higher the efficiency and power are.
What is the function of condenser Mcq?
Explanation: Condensers use the property of
condensation
which is a convective heat transfer process that is associated with a change in the phase of a fluid from the gas to a liquid phase.
Why do we need vacuum in condenser?
A vacuum is maintained in the
condenser so that steam can easily flow and more work can be extracted from the steam in the turbine
; this is the reason why vacuum is maintained in condensers.
What is condenser and its function?
A condenser (or AC condenser) is
the outdoor portion of an air conditioner or heat pump that either releases or collects heat
, depending on the time of the year. Both split air conditioner and heat pump condensers are made of the same basic parts.
Why it is called surface condenser?
It is called the surface condenser
because the exhausted steam and cooling water does not mix up
.
What is use of the air pumps in the condenser?
Air pump is a machine which is used in the condenser
to remove condensate air from the condenser
. Basically,Air pump creates a vacuum in the condenser as nearly as possible, corresponding to exhaust steam temperature. It is used in the condenser to remove both air and condensate from the condenser.
How does a spray condenser work?
The various types of direct contact condensers are: The Spray Condenser.
The coolant is sprayed, using nozzles, into a vessel to which the vapor is supplied
. ... (Flooding is an unstable condition when the vapor flow is such that the downward flow of condensate is interrupted and held up.)
What are the sources of air leakage in a condenser?
(i) Leakage
through packing glands and very small holes in the shell
. (ii) Leakage through joints and vents from atmospheric relief valves and other accessories. (iii) Dissolved gases or air in boiler feed water, which ultimately enters the condenser with exhaust steam.
What do you mean by steam condenser?
Steam Condenser is
a mechanical device which converts the low pressure exhaust steam from the turbine into water
. Or in other words it is a device which is used to condense exhaust steam of the turbine into water. It does so with the help of cooling water circulated into it from the cooling tower.
What are the different types of steam condenser?
-
Jet condensers (mixing type condensers) Parallel flow jet condenser. Counterflow or Low-level jet condenser. Barometric or High-level jet condenser. Ejector Condenser.
-
Surface condensers (non-mixing type condensers) Downflow surface condenser. Central flow condenser. Regenerative condenser.
Which turbine has highest speed?
The specific speed of
Kaplan turbine
ranges from 600 to 1000 rpm. It is a low head axial flow turbine. From the table, we can conclude that the Kaplan turbine has the highest specific speed.
What is the basic principle of regeneration?
What is the basic principle of regeneration? Explanation: In
regeneration steam from condenser is circulated through turbine to increase steam temperature before it enters boiler
. Explanation: Feedwater is preheated so as to decrease the fuel consumption which increases efficiency.
What is the function of condenser in power plant?
In thermal power plants, the purpose of a surface condenser is
to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate)
so that it may be reused in the steam generator or boiler as boiler feed water.
