Abstract:
A hot blast stove for preheating combustion air for an associated blast furnace, having a continuous, substantially cylindrical shaped peripheral wall extending from a base to a domed cover. The peripheral wall includes a first cylindrical portion defined by a refractory ring wall of a predetermined thickness, surrounded by insulation, and enclosed by a continuous metal shell; and, a second, diametrically larger, cylindrical portion disposed above the first cylindrical portion, defined by a continuation of the refractory ring wall of the first portion, surrounded by a predetermined thickness of insulating brick and insulation. The second portion is enclosed by a continuous metal shell which joins the domed cover. An annular interconnecting portion joins the cylindrical portions and includes a metal shell that diverges outwardly from the metal shell of the first portion to obliquely join the metal shell of the cylindrical portion. The interconnecting metal shell provides support for tapered insulating bricks which in turn support the insulating brick in the second portion.
