Injection of OilCosts & Benefits
|Parent Process: Blast Furnace System|
|Energy Savings Potential||
Every ton of oil used can reduce the coke demand by 1.2 tons (Worrell, et al., 2010. p. 84).
|CO2 Emission Reduction Potential||
CO2 reductions will vary depending on the composition of oil, and in particular Carbon and Hydrogen contents.
Injection of Oil Publications
The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for the U.S. Iron and Steel Industry, discusses energy efficiency practices and technologies that can be implemented in iron and steel manufacturing plants. This guide provides current real world examples of iron and steel plants saving energy and reducing cost and carbon dioxide emissions.
Injection of Oil Resources
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.
