Boiler Feed Pump Control Using Variable Frequency Drive
Enhancing energy efficiency of boiler feed pumps in thermal power plants through operational optimization and energy conservation. adjust the weight in a manner mathematically to .
The fixed speed motor load application such as the boiler feed pump supplies direct AC power. The energy saving is obtained by variable speed drive by using pump affinity laws. By using a Variable Frequency Drive (VFD) to slow down a pump motor speed from to 80% can save 50% of energy. Reducing pump speed not only reduces energy consumption but also reduces noise and vibration.
1. Using Variable Frequency Drives (VFD) to save energy and reduce emissions in newbuilds and existing ships Energy efficiency plays the most important role in CO 2 emission reductions, accounting for up to 53% of total CO 2 emission reductions. In pump and fan applications onboard vessels, using Variable Frequency Drives (VFD) can cut

The method of calculation uses an average "emission factor" for each pollutant. The calculating equation is EM = A X EF X (1 - ER/100), where EM = emission rate A = "activity" rate (e.g. flow rate of fuel) EF = emission factor (a fractional value of activity rate) ER = overall emission reduction efficiency, %
