Gas internal combustion engine is a kind of internal combustion engine equipment that uses natural gas as fuel to generate power through combustion. Because of its high efficiency and flexibility, it has been widely used in distributed energy systems. However, in the combustion process of internal combustion engines, nitrogen oxides (NOx) will be produced, causing pollution to the environment. In order to meet the increasingly stringent emission standards, SCR(selective catalytic reduction) denitrification technology has become an effective means to control the exhaust NOx emissions of gas internal combustion engines.
Green Valley Environmental SCR denitrification technology reduces NOx to harmless nitrogen and water under the action of a certain temperature and catalyst. SCR denitration system can work in the temperature range of 200℃-450℃, the most suitable reaction temperature is 320℃-400℃, and the denitration efficiency can reach 90%-98%. Meet the latest national environmental requirements, ultra-low nitrogen oxide emissions and ammonia escape less than 3ppm requirements.
In practical applications, the design of the SCR denitration system needs to consider the flue gas characteristics of the internal combustion engine, such as temperature, NOx concentration and flue gas composition. Systems typically include reducing agent storage and injection systems, catalyst reactors, and control systems that optimize denitration efficiency and reduce ammonia escape by precisely controlling the amount of reducing agent injected and the mixture of flue gas.
SCR denitrification technology of Green Valley environmental protection not only helps to reduce the emission of pollutants, but also responds to the call of global emission reduction. With the progress of technology and the improvement of environmental protection requirements, SCR denitrification technology is more and more widely used in the exhaust gas treatment of gas internal combustion engines. SCR denitration technology is expected to make greater contributions to the realization of clean energy and environmental protection.
