Abstract

A study has been made of the combustion of different waste oils produced in an iron and steel works. Combustion is achieved by injecting the waste oil at flows of 10-20 kg/h in a combustion chamber that simulates the conditions of the blast furnace tuyere zone. The waste oil is preheated to 65-90 °C in order to achieve conditions of fluidity and is injected by spraying into the combustion chamber. During combustion the temperatures and the CO₂, O₂, CO N₂ and H₂ contents of the gases in the combustion chamber are constantly recorded. The efficiency of the combustion of each waste oil is determined.
