Don't Let Your Money Go Up The Chimney

摘要

Siemens VAI Metals Technologies are dedicated to helping customers reduce costs and to keep their blast furnace stoves working at peak performance. The stoves provide a valuable role in making the blast furnace a high thermal efficiency process. The stoves provide the hot blast which supplies a large portion of the blast furnace heat input. They do this by burning the low heating value blast furnace off gas. However, despite all these benefits, the stoves still consume a large amount of energy. The blast heating process is one of the largest energy consumers in the steel plant and also one of the leading sources for CO_2 emissions to the atmosphere. Stoves need to be kept in good condition and equipped with the very latest equipment to help keep the fuel requirements down. This paper will describe how blast furnace operators can increase the efficiency of their stoves which will lead to lower fuel costs. It will describe the various process changes and pieces of equipment available to help achieve this.
