How do I lower my condenser pressure?
9.14 Condenser pressure regulators With air-cooled condensers and water-cooling towers it is possible to reduce the air flow by automatic dampers, fan speed control or switching off fans, where two or more are fitted. The control should work from pressure but can be made to work from temperature.
What is the most efficient steam power cycle?
The Rankine cycle is the ideal cycle for vapor power plants; it includes the following four reversible processes: 1-2: Isentropic compression Water enters the pump as state 1 as saturated liquid and is compressed isentropically to the operating pressure of the boiler.
Which cycle is more efficient for electricity generation?
In most successful combined cycles, the bottoming cycle for power is a conventional steam Rankine cycle. It is already common in cold climates (such as Finland) to drive community heating systems from a steam power plant’s condenser heat. Such cogeneration systems can yield theoretical efficiencies above 95%.
What is the most important part of combined cycle power plant?
The HRSG is a key component of a combined cycle power plant. Its role is to convert as much of the heat as possible from the exhaust gas of the gas turbine into steam for a steam turbine.
How can we increase the efficiency of steam power plant?
Tips to improve steam plant efficiency
- Step 1: Do a Steam Trap Survey. First, a steam trap survey can easily identify leaking or faulty traps and provide significant potential savings.
- Step 2: Understand the Value of Condensate.
- Step 3: Insulate your Steam System.
- Step 4: Look for Steam Leaks.
- Step 5: Start Steam Metering.
Why does steam expand in a turbine?
In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. As that steam flows past a turbine’s spinning blades, the steam expands and cools.
What type of turbine is best when pressure is high and overall flow is low?
Impulse turbines are most efficient for use in cases where the flow is low and the inlet pressure is high. Reaction turbines develop torque by reacting to the gas or fluid’s pressure or mass. The pressure of the gas or fluid changes as it passes through the turbine rotor blades.
Why Pelton turbine is used for high head?
These turbines are generally used for sites with heads greater than 300 meters. The water in a Pelton turbine is moving quickly (high velocity head, figure 2) and the turbine extracts energy from the water by slowing the water down, which makes this an impulse turbine.
Which turbine is used for high speed and minimum discharge?
Pelton has high head and low discharge. Explanation: Based on heads and discharges, turbines are classified into Pelton, Francis or Kaplan. Kaplan has low head and high discharge. Explanation: Francis turbine is a widely used turbine.
