Design and Fabrication of Waste Oil Fired Furnace

Abstract

The study carried out a design and fabrication of an waste oil-fired furnace. The study focused on ensuring a high efficiency in melting of aluminium, by effectively minimizing heat losses, and maximizing heat generation. To achieve this, a composite refractory material consisting of cement, asbestos, and clay was used, and waste oil was splashed which is used as fuel with the help of blower which is running at 3000 rpm and power rating of 1hp. The working pressure of furnace is 5.86 x105 N/m2. Changes in the furnace geometry were negligible indicating a long service life potential. With a useful heat input, the furnace is able to melt aluminium at a pouring temperature of 6600C. The design is considered safe since the working pressure does not exceed the working stress of its casing which is made of mild steel.
