SUMMARY:Advanced operational control of a reheat furnace for efficiency gains using TDL laser-based combustion feedback
DESCRIPTION:Combustion control in a reheat furnace is an often-overlooked opportunity for fuel savings and steel quality improvements.  With recent increases in natural gas and energy costs, fuel efficiency is more important than ever for maintaining viable steel production. Despite this many of today’s reheat firing schemes are based on rudimentary mass flow indicators and minimal control logic resulting in high levels of excess O2 (4%-8%) and significant extra fuel consumption worth hundreds of thousands of dollars annually.   

A simple solution is presented for zone-based combustion monitoring using a TDLAS laser monitoring system in a reheat furnace.   The system has been used to spot failings caused by poor burner calibrations and targeted firebox corrections at a large steel mill. Moving forward control logic updates are planned to help improve furnace efficiencies and reduce fuel consumption.  Furnace corrections and proposed efficiency solutions will be reviewed to illustrate the optimization journey and combustion improvement opportunities.
