The present work describes the design, construction and experimental investigations of an air-blast atomizer for half spray cone angle of 30° using stainless steel for foundry application. Outline detail of experimental setup to investigate effect of injection pressures on spray and flame lengths, the amount of fuel and the time taken to melt some selected materials was studied. An experimental study of air-blast atomization was conducted using the manufactured atomizer in which the fuel (kerosene) flows under gravity at angle 45 o from the tank and was atomized by the oxygen stream flowing in a cylindrical channel from a pressurized oxygen bottle (cylinder). Produced air-blast atomizer was experimentally investigated at different pressures ranging from 3 to 15 bars in the step of 3 bars [6].As the injection pressure was increased from 3 to 15 bars, the spray and flame lengths increases. From 6 to 12 bars, visible increment was observed in the spray and flame lengths due to increase in injected pressure which led to breaking-up of the liquid film into small droplets. As enough pressure was provided from 12 to 15 bars, spray and flame lengths increased appreciably. 0.6 kg of aluminum melted in 13 minutes 43 seconds using 0.5 liter of kerosene; the volumetric flow rate and the mass flow rate obtained was 6.075*10 -7 m 3 /sec and 4.921*10 -4 kg/sec respectively. Similarly, 1.2 kg of brass melted in 17 minutes 13 seconds using 1 liter of kerosene; the volumetric flow rate and the mass flow rate obtained was 9.680*10 -7 m 3 /sec and 7.841*10 -4 kg/sec respectively. The furnace efficiency of 2.2 % was calculated from the theoretical and actual energy used for melting the metal [6].

“…Based on the findings of the study, optimization of the fuel and air flow parameters and re-design of the burner to incorporate automatic ignition system would significantly improve its performance. Madu et al [6] examined the performance of a WLO burner where WLO and kerosene were mixed to ease ignition and increase efficiency. The thermal efficiency of the burner was reported as 66%.…”

The global energy demand has continued to skyrocket, exacerbating the already severe energy problem and environmental pollution, prompting researchers to look for alternative energy sources. Exploration of waste lubricating oil (WLO) as an alternative source of fuel has gained prominence among researchers due to its availability at low cost and the potential to generate energy while providing a safer means of disposal. The main challenge with WLO combustion is proper regulation of fuel and oxidizer during combustion to realize a near stoichiometric result. Additionally, WLO has high viscosity, hence preheating of the oil is necessary to lower the viscosity and enhance atomization, for a more efficient combustion process. This paper presents the optimization of flow parameters for combustion of WLO in a burner system by use of response surface methodology (RSM). The effects of air flow rate, injection pressure and fuel flow rate on combustion performance of a WLO burner were investigated. The highest flame temperature recorded was 1200˚C at an air flow rate of 1 m 3 /min, fuel flow rate of 0.08 m 3 /hr and injection pressure of 20 bar. Tests on physical and chemical properties of WLO were conducted and characterized according to ASTM standard to ascertain its potential as an alternative fuel. The calorific values of WLO from petrol and diesel engines were found to be 41.23 MJ/kg and 42.65 MJ/kg respectively. Therefore, recycling of WLO by utilizing it as a fuel for burners has double benefits of mitigating environmental pollution and harnessing energy for process heating and power generation.
