Joseph Guardia was sentenced to 47 years in the Illinois Department of Corrections, with credit for the 881 days he was already in jail.
Kromelis died nearly seven months after Guardia set him on fire in 2022.
The 75-year-old Kromelis was a familiar face in downtown Chicago.
He earned the nickname the "Walking Man" because he was often seen roaming the area on foot.
