Abstract
Fine sawdust obtained from compressed wood is homogeneously blended with an equivalent amount of liquid wax at a sufficiently elevated temperature to release substantially all moisture from the sawdust and to induce molecular activity in the wax and sawdust to cause full saturation of the compressed wood particles with wax. The hot blended material is cooled and milled to a highly uniform mix, followed by compaction of the material without adhesive additives into the finished product.
Claims3
A method of producing a solid fuel element useful as an igniter in a solid fuel package comprising the steps of:
- blending approximately equal parts by weight of dry powdery wood particles at room temperature derived from the sawdust of cell bound moisture free compressed wood with refined liquid paraffin wax having a melting point of approximately 125.degree. F. preheated to approximately 350.degree. F. to an ultimate blended material temperature of approximately 250.degree. F., thereby ridding the wood particles of free moisture and activating the molecules of the wood particles and liquid wax sufficiently to cause the wood particles to be completely saturated with the liquid wax, cooling the blended material while conveying it in a thin layer slowly through a cooling chamber until the blended material is at a temperature of approximately 56.degree. F., milling the blended and cooled material, and then compacting the material in a rigid compression chamber under a pressure of approximately 22,000 psi to form a dry solid fuel element.
