Flue gas gaseous composition monitoring
Overview
Air pollution is a major global issue and its affects can be seen throughout the world. Emissions from industrial processes, vehicle exhaust, and fires have all been linked to numerous adverse health outcomes, including increased hospitalizations, exacerbation of asthma symptoms, and pre......
Atmospheric Environment Standard
Atmospheric Environment Standard
The Earth’s atmosphere is composed of air, dust, natural gases, and aerosols. Over the years, human activities have caused an increase in air pollution, which has been detrimental to the health of both humans and other living organisms. Air pollution is caused by......
Oxygen Blowing Open Hearth Fume Control
Air Pollution Control of Blast Furnace Flue Gas
Due to the burning of fuels such as coal, oil and gas, flue gas will always be produced by industrial production, especially in the process of blast furnace smelting, resulting in large amounts of dust, sulfur dioxide and other pollutants in the dis......
Safety Matters When Molten Iron Injects Granular Magnesium Desulfurization
Safety Guidelines for Magnesium Desulfurization with Iron Blast Particle Jetting
The practice of using particle jetting to desulfurize molten iron is a widely used and reliable method in steel production. The technique enables the quick and efficient removal of sulfur out of the molten iron and r......
Combustion-supporting desulfurizer
NOx and SCR (Selective Catalytic Reduction)
Presently, part of the energy generated by the combustion process is wasted as nitrogen oxide (NOx) emissions into the atmosphere. The problem of NOx emissions is so significant that in the future, power plant operators must comply with newly establishe......
