| Summary: | Energy is one of the indispensable factors for continuous development and economic growth. The industrial sectors consume a significant amount of energy in Malaysia. This paper is investigated and analyzed the energy use in industrial boilers fan motor, energy savings and emission reduction in Malaysia by using energy audit data. Energy savings using VSD by modulating fan speed has been estimated as well. It has been found that 68,923MWh, 132,922MWh, 78,769 MWh and 49,230MWh electrical energy can be saved for 40, 60, 80 and 100 motor loadings, respectively for 20 speed reduction. Similarly, 139,412MWh, 268,866, 159,328MWh, and 99,580 MWh electrical energy can be saved for 40, 60, 80 and 100 motor loadings, respectively for 60 speed reduction. Along with energy savings, 69,770,744 kg, 134,558,329 kg, 79,738,065 kg, 49,836,603 kg of CO2 emission can be avoided for the associated energy savings as a result of energy savings using VSD for 40, 60, 80 and 100 motor loadings. Moreover, 32,503,558 GJ of fossil fuel can be saved for the flue gas temperature reduction as a result of reducing fan motor speed reduction. It is clear that the use of VSDs leads to substantial energy savings and an enormous reduction in emissions. |
