Design, Construction and Testing Of a Burner That Uses an Admixture of Used Engine Oil and Kerosene for Foundry Application

Abstract

An admixture burner for the atomization and combustion of used engine oil and kerosene for foundry application was constructed and tested to reduce the cost of operation in the foundry since the fuel is easily accessible, in addition to avoid pollution by the incessant dumping of the used engine oil. The nozzle, springs, screws, tank and the fuel hose were predominantly used materials for its construction. A test was carried out to determine the time taken for some selected engineering materials (copper, aluminum, brass, and lead) to melt using the admixture burner with an appropriate combination ratio of 1:5 for kerosene and used engine oil and the ratio of 15:1 for air and fuel respectively, which was considered to be the most reactive, because it ignites easily compared to other ratios. The time taken for 1kg of each selected engineering materials to melt were 49, 15, 22 and 7 minutes for copper, aluminum, brass and lead respectively. The burner has a thermal efficiency of 66%. Experiment also showed that that the density of the admixture, decreases with an increase in the temperature making it easy to mix and ignite for combustion.
