ABSTRACT:
An apparatus for melting solids which is particularly designed to melt tar billets without overheating and thus causing pyrolysis of the solid tar. The apparatus in its principal embodiment utilizes a solid horizontal plate having a plurality of parallel ridges separated by parallel fluid conducting channels, the plate being heated from beneath by a special burner arrangement and causes the tar to melt and then drain into a collector trough rather than remain adjacent the heating surface. The apparatus utilizes vertical feed tar billets which are forced against the melting plate under action of gravity with or without auxillary pressure applying means, and a specialized burner, manifold and stack structure provide for proper removal of burned gases while allowing the easy loading of the vertically stacked tar billets.
