The HVOF system CJS of the company Thermico GmbH & Co. KG is operated with a hydrogen-stabilized liquid fuel oxygen combustion. The combustion process takes place in two steps in order to realize improved control of the level of thermal energy introduced into the process. The hydrogen is burned with excessive oxygen in a short subsonic high pressure combustion chamber. Because of its lower reactivity, the injected liquid fuel is only burned in the supersonic section of the nozzle downstream of the throat. The regulation of flow temperature and velocity is considerably decoupled by this design and thus allows processing of very fine powder fractions without overheating. The powder injection takes place here radially.
