Abstract
The thermal energy can be collected whenever it is available and be used whenever needed with an effective application of Heat Energy Storage. Heat energy storage can be used with any heating system like electric heating, waste heat or solar system. Because of intermittent source of solar energy heat energy storage system is mostly recommended and influencing the sector. The experiment was performed at Kshitija stone crushers Pvt.Ltd., Wadgaon, Tal.-Murtizapur, Dist-Akola (M.S.), India. On thermal energy storage using Concrete block as the solid media sensible heat storage material because it is locally available at low cost and high heat storage capacity. Cooling water at high temperature flowing to radiator from Diesel engine of power generation unit is used as heat transfer fluid (HTF) in order to reuse waste heat energy. The concrete storage prototype is composed of concrete heat storage block with embedded pipe. The embedded pipe was used for transporting and distributing the heat transfer medium while sustaining the pressure. The experiment was carried in two stages i.e. charging and discharging, where energy stored while charging and retrieved while discharging. The concrete block stores the thermal energy as sensible heat. Thermal performance of Thermal Energy Storage (TES) such as charging and discharging time, radial thermal distribution, energy efficiency has been evaluated. For the charging and discharging experiment it was found that the increase or decrease in rate of energy storage and retrieval depends on the temperature and mass flow rates of HTF. The results shows that increasing the HTF flow rate increases the overall heat transfer coefficient, thereby enabling faster exchange of heat and reduces charging and discharging time. It can be conclude from this experiment that thermal energy storage can also play useful role in waste heat management system.
