Abstract

In this paper energy use , energy and bill savings, emission reduction and pay period using high efficient motor, variable speed drive by modulating speed of boiler and compressor has been estimated using energy audit data. It has been found that 68,923 MWh, 132,922 MWh, 78,769 MWh and 49,230 MWh of energy can be saved for 40, 60, 80 and 100 motor loadings, respectively for 20 speed reduction in the boiler system. Corresponding bill savings for the aforementioned energy savings have been found to be US 4,411,052, US 8,507,028, US 5,041,202, and US 43,150,751 for 40, 60, 80 and 100 motor loadings, respectively for 20 speed reduction in the boiler system. Energy savings and bill savings resulting from the use of high-efficiency motor in air compressor are 6703 MWh, 8251 MWh, and 10571 MWh, total energy, can be saved for 50, 75, and 100, motor loadings, respectively. Similarly, bill savings for the preceding amounts of energy savings are US 428,984, US 528,042 and US 676,538, respectively. It is also clear that the use of high efficiency motor and VSDs leads to substantial energy savings and an enormous reduction in emissions.
