Abstract

A tangent spin furnace providing a combustion chamber of metal which is unlined with any refractory material but whose temperature is maintained below the self-destruct level by combustion air being introduced into the combustion chamber between a plurality of slats defining the combustion chamber and disposed in spaced relation to each other so that they define longitudinal slots. Thus there are slots for the introduction of combustion air between the slats so that a sweep of combustion air is maintained peripherally inside of the combustion chamber over virtually the entire inner surface thereof. Without refractory material lining the combustion chamber overheating is avoided by the cooling effect of the sweep of combustion air.

Claims4

Dependent claims

A tangent spin furnace comprising,

(a) a plurality of slats defining a generally cylindrical combustion chamber,
(b) each slat having longitudinal inside and outside sections defined by a longitudinal bend, the planes of the inside and outside sections disposed at an oblique angle to each other on opposite sides of the longiutdinal bend,
(c) at least a portion of each of the outside sections of the slats overlapping the inside sections of the underlying slats,
(d) at least a portion each of the inside section of the slats overlapped by the outside sections of the superposed slats,
(e) the overlapped portions of the slats arranged in spaced relation to each other to define longitudinal passages for air stream filaments of combustion air to enter the combustion chamber,
(f) the passages for air stream filaments being positioned generally tangentially to the entire length of the interior of the combustion chamber to direct the combustion air to peripherally traverse the inside of the combustion chamber over the inside section of the slats,
(g) the outside section of the slats being swept by the air stream filaments entering the passages,
(h) a plenum surrounding the combustion chamber for supplying the air stream filaments of combustion air thereto, and
(i) a burner disposed coaxially with the combustion chamber.
