  • Abstract:

A crucible furnace was designed and constructed from locally sourced materials and
fired using spent engine oil (SEO). While combustion of SEO was effective during evaluation
which was done with the melting of Aluminium-Silicon alloy scrap metals in the crucible furnace,
its continuous availability cannot be guaranteed. Experimental analysis was carried out with SEO
mixed in proportions 1 : 5, 1 : 2, 1 : 1, 2 : 1 and 5 : 1 with diesel and kerosene with a aim to reduce
cost. The fuel samples were comparable with the conventional fuels in terms of the physico-chemical
properties evaluated. The cost of the admixed fuel reduced as the quantity of SEO in the mixture was
increased. Similarly, the least amount of time taken to combust 450 ml was achieved with the fuel
mixture with the least SEO ratio. Maximum temperature build up of 190 oC was achieved when the
450 ml fuel sample had kerosene as two third of its content, and maximum of 124 oC when equal
proportion of diesel was added to SEO. Moreover, for melting purposes, admixtures with diesel will
be recommended because of its higher calorific content that is burnt slowly. This is suitable for the
latent heat required in melting.
