The incident occurred shortly before 10 a.m. as the Chinese American Heritage Foundation's train float passed through the intersection of Orange Grove Boulevard and West Green Street.
The blaze was quickly extinguished and the float was towed by a heavy-duty truck. No injuries were immediately reported.
