Analysis of Peltier Characteristic and Cold Side Treatment for Thermoelectric Generator Module at Brick Kiln Furnace

Abstract

Alternative energy sources are an urgent needed. Heat as alternative energy source that is wasted a lot, a brick kiln furnace is one for example. High temperatures up to 173 degrees Celsius in furnaces can be converted to electrical energy by peltier component. Besides the price, peltier characteristic is a decisive factor in peltier selection. Commonly in Indonesia’s market, peltier has a various prices, TEC type is generally sold at a price range IDR.35,000.00 to IDR.100,000.00. The most common peltier in the market is the TEC1-12706 type, available in electronics stores sold for IDR.35,000.00 other TEC types taken for example is TEC1-12715 type which have a larger current rating sold online with price IDR.100,000.00. In addition to TEC type is also available TEG-SP1848 type with prices ranging IDR.65,000.00. The release of heat on the cold side greatly affects the output of electricity produced by peltier so that the treatment on the cold side is closely related to the output of electricity generated. Selection of peltier type based on price/ characteristics and treatment to the cold side are crucial factors for thermoelectric module design at brick kiln furnace application. The result shown TEC1-12715 best in current output but lowest in output voltage. The best voltage and power performance especially for high temperature is TEG-SP1848 peltier, best threatment for cold side is use water flow. Use TEG-SP1848 as thermoelectric device and water flow as cooling system successfull to build thermoelectric generator for brick klin furnace application.
