A REVIEW ON WASTE HEAT RECOVERY OF BOILER PLANT USING HEAT PIPE HEAT EXCHANGER

The consumption of hot air presents a significant part of the nation's energy consumption. And hence the cost of that energy is to regain heat from the waste warm air that is discharged to the sewer each day. The potential for economic waste air heat is recovery depends on both the quantity of heat available and whether the quality fits the requirement of the heating load. Heat pipes with heat exchanger are useful device for the recovery of waste heat. Large quantities of heat can be conveyed through a small cross-sectional area over a long distance with no extra power input to the system. Some applications of heat pipes are in the area of heat exchangers for heat recovery medicine, electrical and electronic equipment cooling and as spacecraft by replacing the conventional fluid in heat pipe with Nano fluid of the heat pipe heat exchanger enhancement in performance of heat pipe heat exchanger can be obtained. By using developed test rig, energy saving potential for heat source at various temperatures would be expected
