Energy Conservation in Boiler by Variable Speed Drives (VSD)

Mr. Bhavesh Jinjala, Prof. Rashmikant. N. Shukla

Applications of technologies have tremendous potential to reduce industrial energy use. Industrial energy use can also be reduce using variable speed drive in motor operated system, high efficient motors, efficient nozzles in compressed-air system, waste heat recovery system in boilers. Energy saving by management including energy audit, training programs and housekeeping beside some energy management practices in the world has been reviewed. Energy saving technologies, such as use of high efficiency motors (HEMs), variable speed drives (VSDs), economizers, leak prevention and reducing pressure drop has been reviewed. Based on energy saving technologies results, it has been found that in the industrial sectors, a sizeable amount of electric energy, emissions and utility bill can be saved using these technologies. Payback periods for different energy savings measures have been identified and found to be economically viable in most cases. Finally, various energy-saving policies for few selected countries were reviewed.
