<p>A fuel briquette is described in which improved combustion is achieved by producing the briquette in a shape which yields a very large external surface area. This is achieved inter alia by forming grooves and recesses in the outer face(s) of a block of material and by forming holes through the block which further improved the draught during combustion. When the briquette is formed by a wet process, the drying time is decreased due to the very large external surface area. A preferred briquette is formed from a coal and/or coke mixture with an adhesive of a cement such as Portland cement or lime added.</p> |
