Energy plays a very important role in industry , Industries could be classified into heavy energy consumer , medium energy consumer and low energy consumer . Organization have started doing energy audits in their plants , offices etc .Such studies has highlighted waste of energy and requirement of energy efficient technology.
Some areas for energy cost reductions.
OFFICE:
Large Corporations or factories have bigger administration offices like accounts , sales , purchase,human resources ,production planning ,canteens ,rest rooms ,common rooms etc .Each dept or sections has certain utilities like air conditioners , photocopiers ,fans ,air washers ,lights etc .Cost reduction in energy bill can be achieved through proper monitoring optimization of equipments
LIGHTING
HEATING
COOLINGFANS
PLANTS
Any manufacturing unit would consume ;energy for its production purpose. With monitoring and proper utilization of equipments We can have substantial cost reduction in energy cost .Energy could be in various form thermal or electrical. Few Ideas
PRIME MOVERS ( MOTORS ) :
Replace higher rating motors by lower hp motors
Use variable frequency drive where ever possible
Replace old motors with energy efficient motors
AIR CONDITIONING :
Set temperature to comfort levels .
Insulation to be placed on all cooling surfaces
COOLING TOWERS:
Install Plastic blades instead of metal casting blades for fan motor
Install temperature sensors for temp of water circulated in the tower
BOILERSFURNACES /OVENS
Use Heat exchanger to recover heat
Heat recovery from flue gases
FUEL ALTERNATE :
Use Gas as fuel instead of high speed diesel or low diesel oil
ENERGY ELECTRICAL :
Use capacitor bank to improve power factor of electrical distribution
