Abstract

This work shows an energy and exergy analysis of blast furnace gas and tar used as fuel in a thermal power plant. The blast furnace gas is produced as a residual gas during preparation of pig iron in a steel mill plant, and tar is also formed as a residual liquid originated from pig iron conversion to steel in the steel mill. The steel mill plant uses the residual blast furnace gas and tar as energy source in a Rankine cycle power plant. The power plant used as a case study is located in the state of Minas Gerais, Brazil. Computer simulation was executed using data obtained from the power plant. The results offer ways to control fuel combustion, reduce pollutant exhaust gas levels, and increase energy availability.
