Thermal power plants are the main source of electricity,but their units generate a large amount of exhaust gas containing nitrogen oxides during operation,leading to various environmental problems.In order to reduce the nitrogen oxide content in the exhaust gas emitted by thermal power units and improve the environmental benefits of thermal power units,an automatic control and treatment system for thermal power unit exhaust gas was designed based on the urea hydrolysis ammonia denitrification technology.The results show that the system can quickly adjust the temperature of the pyrolysis furnace,resulting in a 82%reduction in nitrogen oxide content and exhaust gas emissions from the thermal power unit.This system can effectively reduce the nitrogen oxide content in the exhaust gas emitted by thermal power plants,thereby reducing the environmental pollution caused by the production activities of thermal power plants.
