Which condenser is used in power plant?
A surface condenser or steam condenser is a water-cooled shell and tube heat exchanger used to condensate the exhaust steam from the steam turbine in thermal power stations: the steam is converted from gaseous to liquid state at a pressure level below atmospheric pressure.
Which type of condenser is most suitable for propulsion turbine?
Titanium condenser tubes are usually the best technical choice, however titanium is very expensive material and the use of titanium condenser tubes is associated with very high initial costs.
Which condenser is suitable for high power capacity plant?
The main advantages of incorporating a steam condenser in a steam power plant are as follows: It increases the efficiency of the power plant due to increased enthalpy drop. It reduces back pressure of the steam which results in more work output.
What is the role of condenser in a steam 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.
What is the ideal site for power plant?
The plant should be far away from residential area to avoid nuisance from smoke, fly ash and noise. Nature of Land : Many power plants have failed due to weak foundations. Land (soil) should have good bearing capacity to withstand dead load of plant.
What is the difference between jet condenser and surface condenser?
1 Types of Surface Condensers: 1.2. 1.1 Down flow condenser. 1.2….Difference between surface condenser and jet condenser.
| S.NO | Surface Condenser | Jet or Direct Contact Condenser |
|---|---|---|
| 3 | Condensate is reused. | Condensate is wasted |
| 4 | It requires large quantity of circulating water. | It requires less quantity of circulating water |
Which turbine is used in steam power plant?
In order to match steam production to heat demand, there are three types of steam turbine in common use for CHP plants. These three are called a back pressure steam turbine, an extraction steam turbine and a condensing steam turbine. Each type will suit a different configuration of plant.
How can I make my condenser more efficient?
Reducing cooling water temperatures is a sure-fire way to improve condenser performance: A decrease in cooling water temperature of 10 degrees F can improve the overall heat rate of a power plant by 1%.
What factors should consider to select a power plant?
The selection of the site for a power plant depends upon many factors such as cost of transmission of energy, cost of fuel, cost of land and taxes, requirement of space, availability of site for water power, storage space for fuel, transport facilities, availability of cooling water, nature of load, degree of …
Which power plant has high capital cost?
Power Generation/Comparison
| Power Station | Rank | Initial Cost |
|---|---|---|
| Steam Power station | 2 | Are lower than those of Hydro & Nuclear. |
| Hydro Power station | 3 | Are very high because of dam construction. |
| Diesel Power station | 1 | Lowest compared to all other power stations. |
| Nuclear Power station | 4 | Highest due to complex nuclear reactors. |
How is a surface condenser used in a thermal power plant?
A surface condenser or steam condenser is a water-cooled shell and tube heat exchanger used to condensate the exhaust steam from the steam turbine in thermal power stations: the steam is converted from gaseous to liquid state at a pressure level below atmospheric pressure.
How does a condenser improve a power plant?
With a focus on combustion controls, furnace tuning, fuel switches, and turbine upgrades to supply heat rate improvements, condenser performance can be underrated. Result: frequent interruptions for cleaning and repair with significant impact to the plant heat rate and power output capacity. High condenser vacuum improves power plant capacity.
What happens when a condenser is fouled in a power plant?
Condenser fouling leads to a decreased condenser vacuum which in turn affects the fuel conversion efficiency and leads to an output decrease or capacity decrease of the plant. When the condenser operates under a vacuum, it pulls the steam which improves overall performance of the turbine.
Why is a condenser used in a steam turbine?
Condenser is mainly used to convert the low pressure steam at the end of the turbine to liquid so that the process is continued. As the pressure in the last phase of turbine is very low so the pressure in the condenser must be lower than that so that the low pressure steam can flow to condenser and get liquefied.
