Pressure drop from boiler drum to superheater is due to the decrease in steam density and frictional losses.

• Pressure drop occurs due to the decrease in steam density as it passes from the boiler drum to the superheater.

• Frictional losses also contribute to the pressure drop.

• The pressure drop is necessary to ensure proper steam flow and temperature control in the superheater.

• Factors such as pipe length, diameter, and ben...read more

To monitor and control the oxygen levels in the flue gas between the economizer and air preheater.

• Installing an O2 analyzer between the economizer and air preheater helps optimize combustion efficiency.

• It allows for real-time monitoring of oxygen levels in the flue gas, enabling adjustments to the air-to-fuel ratio.

• Maintaining the optimal oxygen levels ensures complete combustion and reduces fuel consumption.

• By control...read more

Maintaining above 120 degree ESP temperature is important for efficient operation and prevention of corrosion.

• Higher ESP temperature ensures efficient removal of particulate matter from flue gas.

• It helps in preventing corrosion of the ESP components.

The critical speed of a turbine is the rotational speed at which the turbine experiences resonance and can lead to catastrophic failure.

• Critical speed is the speed at which the natural frequency of the turbine matches the excitation frequency.

• It is important to operate the turbine below its critical speed to avoid resonance.

• Resonance can cause excessive vibrations, leading to fatigue and failure of turbine components.

• T...read more
