ABSTRACT:
Method for calcining carbonaceous blocks into carbonaceous bodies, in which either a continuous or intermittent operation furnace is used. After placing carbonaceous blocks to be calcined onto the loading platform of a cart, a containment structure or enclosure structure is formed around the carbonaceous blocks including a barrier, which is held away from and is adapted to completely enclose the carbonaceous blocks, with the optional exception of barrier formed on the surface of the loading platform on which the carbonaceous blocks rest. The barrier being effective to prevent seepage of air or gases therethrough during calcination. The containment or enclosure structure for implementing the method comprises a conventional cart for continuous and intermittent operation furnaces overlaid by a stacked arrangement including two side-by-side walls of refractory material wherebetween a barrier of carbonaceous powder is interposed, and a cover, including two slabs also formed from refractory material and arranged in two layers wherebetween a further barrier of carbonaceous powder is provided. An additional barrier of carbonaceous powder may be optionally provided on the loading platform of the cart.
