A Comparative Study on FeCrAl Alloy and NiCrSi Alloy Materials as Heating Element at Low Energy Oven

Abstract

Abstract In this era we need lower energy consumption in electronic devices, example on oven. There is a heating element inside the oven. The heating element should produce high temperature with low energy consumption. Heating element in this research use FeCrAl alloy and NiCrSi alloy. FeCrAl alloy or Kanthal A-1 wire consists of 20% chromium, aluminum and ferum. NiCrSi or Nichrome 80 consist of 80% nickel, 19,5% chromium and 1,45 silicon. The reason using these both wire, because both of wire have high resistivity and produce high temperature. In this research using FeCrAl alloy and NiCrSi alloy 0,8 mm with variations in coil diameter 10 mm. Both of wire applied in oven 40 cm x 40 cm x 50 cm to produce 40 °C . From FeCrAl alloy dan NiCrSi alloy to produce 40 °C with same voltage input, NiCrSi 0,8 mm with 10 mm diameter produced power 170 Watt took 4.4 minutes to reach 40 °C and the energy consumption is 12,5 Wh. With same diameter FeCrAl produced power 210 W took 4,4 minutes to reach 40 °C and energy consumption is 15,4 Wh. From the data results show that the NiCrSi alloy has lower resistance value than the FeCrAl Alloy. It can be concluded that NiCrSi alloy diameter of 0.8 mm with a winding diameter of 10 mm consumes low energy in generating heat.
