Abstract
In order to provide a block (1) of solid fuel material which has good burning time, good flame form and a clean flame, the block (1) is comprised of a mixture of solid particulate, cellulosic, organic combustible material, and stearic or palmitic acid together with, optionally, one or more fatty acids or esters. The mixture has a density of from 0.94 to 1.01 gm/cc. The block (1) has a slit (2) extending longitudinally of the block. The slot (2) communicates with a space (3). Combustible gases collect in the space (3) and form a flame at the mouth of the slit (2).
Claims13
