The objective of this research is to develop an existing crucible furnace fueled by diesel fuel into an energy saving LPG fueled furnace. The Non- ferrous melting furnace will be used to melt Aluminium and Copper alloys. The results of the research are as follows: 1. The furnace and equipment improvements outlined in this research will save an average fuel cost of 26.90 percent when using diesel oil. 2. When comparing the use of LPG fuel with diesel oil to melt aluminium alloy, LPG use results in an average cost saving of 43.18 percent as compared to diesel, while copper alloy melting results in an average cost saving of 50.83 percent. The world energy crisis has impacted economic growth in the developing countries mainly due to the high costs of importing energy such as crude oil from middle eastern countries where the high price of the oil has lead to a higher cost of products. Thus manufacturers must consider this when embarking of significant capital expenditure. It is believed that alternative energy is the way to relieve the energy crisis situation. Using suitable energy is one way to save on production costs. Foundries which produce non - ferrous metals such as aluminium and copper Alloy still use oil crucible furnaces as the source of heat energy. If they change the energy source from oil to be liquefied petroleum gases (LPG) the melting cost will be decreased. This research was the experimentally conducted by melting non - ferrous metals within a crucible furnace using either LPG or diesel oil and then comparing the consumption levels. Before the experiment we modified an existing crucible furnace which used diesel oil to be the experiment furnace. However for reference data this researcher took the Capacity table of crucible furnaces from Pyro - Industrial Systems Company U.S.A.
