Description
Summary:Mini compact crucible furnace prototype is aimed at reducing dimensions and weight without sacrificing capacity. The performance test was conducted in order to found its weaknesses. The performance parameters tested were crucible, support, and exhaust pipe as economizer. The crucible dimensions are (ø170 x 250) mm and (ø110 x 210) mm while the support's high are 80 mm and 40 mm. The test was done in two conditions which are with and without economizer. The performance is defined by the temperature change rate in melting 3 kg of aluminium. A digital infrared thermometer was used to measure temperature changes. The result shows that position of economizer is too low so the residual gas combustion could not smoothly thrown out and it flow back and collide with the combusted gas from high pressure stove below. Reducing the heating chamber could enhance the furnace efficiency but economizer should be in proper position and support should be in optimum height. Redesign of heat insulator should be done related to the smash by combusted gas from high pressure stove.
