This invention consists of a new thermal dismantling method that enables reaching very high temperatures of 1000 oC for transforming any quality oil shale into directly refinable shale oil and to shale gas equal to natural gas, and as a by-product producing water and hot air, resulting in ash production where the ash is transformed into solid fuel by adding organic and non-organic additives and the residue of the burned solid fuel is used as raw material for other industrial products such as clinker, insulation material; by using its own solid fuel to raise and reach the high range temperature without the need to use any other type of fuel and without using water for the cooling system Oil shale is one of the rocks in which organic prong is mixed with widely variant of non-organic metal prong. This mixture contains a broad spectrum of mineral elements and it has the ability to generate all traditional sources of energy when treated by the thermal dismantling method. The thermal dismantling method is based on separating the volatile section which consists of shale gas, shale oil and water, the remaining section (the non-volatile section) is called the ash. The ash is taken, and then appropriate additive materials in specific quantities are added to it to produce the solid fuel. In such a way, it can be claimed that the following equation is maintained in an economic criteria and environmental standards: Oil shale = Solid Fuel + Crude oil + Natural Gas
