Method for generating combustion gas from a solid oxygen precursor material and a solid reductive material which are disintegrated and associated device

摘要

Generating gas by combustion of a solid reducing material (2) with an oxidizing gas, comprises extemporaneously generating an oxidizing gas containing at least 50 vol.% oxygen by thermochemical decomposition of a solid material (1), and combusting the solid reducing material with the generated oxidizing gas. An independent claim is included for a device for generating combustion gas, comprising a first chamber (10) that contains the solid material capable of thermo-chemically decomposed by generating the oxidizing gas and is equipped with an initiation unit for thermochemical decomposition of the solid material and a unit for supplying the generated oxidizing gas, and a second chamber that is connected with the first chamber, contains the solid reducing material and is equipped with a unit for exhausting the combustion gas and optionally an ignition system.
