High-frequency plasma combustion nozzle based on ammonia gas and application

Abstract

The invention relates to a high-frequency plasma combustion nozzle based on ammonia gas and application, the high-frequency plasma combustion nozzle based on ammonia gas comprises a ground electrode, a main channel is formed in the ground electrode, and the ground electrode is provided with an insulation sealing end and a spraying port communicated with the main channel; one end of the high-voltage and high-frequency electrode penetrates into the main channel closing section from the closed end of the ground electrode; the gas inlet channel is used for preheating ammonia reaction gas and reducing the temperature of the two electrodes at the same time, and the gas inlet channel is communicated with the main channel, so that when the preheated ammonia reaction gas flows through the end parts of the high-voltage and high-frequency electrodes, the preheated ammonia reaction gas is punctured and ionized to form an ammonia gas plasma beam and a hydrogen combustion beam after ammonia decomposition, and the ammonia gas plasma beam and the hydrogen combustion beam are ejected through the ejection port. According to the high-frequency plasma combustion nozzle, the problem that an electrode cannot be continuously used for a long time due to frequent replacement in the prior art is solved, meanwhile, electric energy and ammonia energy are effectively combined to be synergistically and efficiently converted and utilized, and the problem that ammonia gas cannot be directly ignited and combusted at normal temperature and normal pressure is solved.

Description

technical field [0001] The invention relates to the field of combustion nozzles, in particular to an ammonia-based high-frequency plasma combustion nozzle and its application. Background technique [0002] The DC arc plasma torch is a successful case of applying plasma to garbage disposal. The plasma torch is powered by anode and cathode and then discharged to generate an electric arc to spray out flames to burn garbage. Therefore, the anode and cathode will generate extremely high temperatures. , high temperature damages the cathode and the cathode more seriously, and water cooling is necessary, which also wastes electric energy. [0003] As a good hydrogen storage medium, ammonia will not produce greenhouse gases after combustion. However, due to its high ignition point and slow heat transfer speed, it often cannot be stably and fully combusted, resulting in the low utilization rate of ammonia energy and making it difficult to be widely used. At present, the application o...
