Abstract
The improvement in a walking beam oil country tube reheat furnace comprises a first row of burners positioned in spaced relationship and transverse the furnace hearth with each of the burners containing a refractory housing positioned in the limited space between the walking beam pass line and the hearth of the furnace. The burner includes a burner body and a centrally disposed fuel tube so as to define an annular air chamber thereabout. The burner includes a 90.degree. bend so as to fire in parallel relationship to the pass line. The method of retrofitting a top fired walking beam furnace includes inserting at least one unitized bung of said spaced burners through the furnace floor and into the space between the pass line and floor and firing the burners in parallel relationship with the pass line.
