The important components in Thermal Power Plant:-

1. Electric Generator : derives motion from steam turbine & generates electricity.

2. Steam Turbine: Generates high-speed rotation with help of high energy fluid.

3. Condenser: Collects and removes heat from the steam.

4. Cooling Tower: Removes excess heat from the condenser & increase efficiency.

5. Stack: Ensures proper ventilation & maintain safe & clean environment.

6. Boiler?

Process Variable (PV):

1. Steam Pressure

2. Steam Temperature

3. Coal combustion Flow Rate

4. Feed water Flow Rate

5. Condenser pressure

Manipulated Variable (MV):

1. Feed water pump speed

2. Steam turbine valve position

3. Boiler fuel supply

Focusing on the use of pump function in WTP process:

Pumps play many roles in water treatment plant.

They move water from one place to another, and they provide added pressure that's sometimes needed to perform treatment functions.

Pumps are used to inject water treatment chemicals, to supply compressed air, and to move treated water to its point of use.

The implemented pump in the WTP process:

1) Low-lift pump

Move large volumes of water at relatively low discharge pressure.

Suitable for the pumping of surface water.

2) DAF Compressor

Supplying and regulating the air needed to create microbubbles for the flotation of suspended particles and containment.

3) Backwash pump & compressor

When the filter’s pores become clogged, they need to be cleaned.

One of the ways is to use this pump.

Where it can reverse the flow and increasing the velocity at which water passes back through the filter.

While for the compressor it will produce constant flow of pressurized oxygen.

4) DAF pump

To remove suspended solids, oil and grease from water

Involves the used of fine air bubbles to float and separate containment form the water

These bubbles attach themselves to the suspended particles, reducing their density and causing them to rise to the surface removal

5) Return pump

Known as recirculation pumps.

A liquid has to be pumped from one tank into another tank.

6) Sludge transfer pump

Be able to handle thick liquid with high solid content such as sludge.

Process and moves waste fluids with high solid content.

7) High-lift pump

Known as booster pumps.

Pumps that discharge treated water into arterial main.

Increase the pressure in zones far from the distribution system.

Key Processes:

Fuel Combustion in Boiler: Fuel (e.g., coal, oil, gas) burned to produce heat.

Water to Steam Conversion: Heat from combustion turns water into high-pressure steam.

Turbine Operation: Steam's kinetic energy causes turbine blades to rotate.

Electricity Generation: Turbine's rotation drives an electric generator, converting mechanical energy to electrical.

Steam Condensation: Steam is cooled and condensed back into water in the condenser.

Cooling and Water Recirculation: Warm water from condenser cooled in a tower; cold water recycled back.

Control Applications:

Boiler Control: Monitors and controls combustion conditions like air-to-fuel ratio and temperature.

Turbine Control: Manages turbine's rotational speed to match power output with grid demand.

Turbine Control: Manages turbine's rotational speed to match power output with grid demand.

Condenser Pressure Management: Keeps pressure within condenser low for efficient condensation.

Cooling Tower Regulation: Adjusts water flow rate and sometimes fan operations to maintain desired water temperature.

Feed Water Control: Ensures consistent water level in the boiler by adjusting feed water pump speed or valve position.
