ABSTRACT:
This invention relates to a solid combustible element and a method for manufacturing it, whereby in the element an open or closed internal space is provided, and in this space is placed a chemical product for disintegrating a combustion deposit layer. When burning this element in a combustion device, such as e.g. a hearth or a stove, the product is released so that a combustion deposit layer (e.g. consisting of soot, ash and tar) formed on the walls of the combustion device or the smoke flue is disintegrated. The element is preferably formed by compressing an amount of loose particles of one or several solid combustible materials, such as among others wood waste and sawdust, without adding any binding agent.Such an element can be manufactured at lower raw material and production costs than the known elements in which such a product is incorporated.
