Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sulfur trioxide analysis instrument and method. Background technique [0002] Sulfur trioxide in the flue gas of thermal power plants has great harm to the operating performance of the equipment and the environment, such as blocking and corroding downstream equipment, reducing power plant efficiency, increasing the turbidity of exhaust smoke, forming PM2.5 as a precursor, and endangering human health Wait. Because sulfur trioxide is easily combined with water vapor in the flue gas to form sulfuric acid vapor, which condenses on the heating surface whose wall temperature is lower than the acid dew point, causing acid dew point corrosion. The more sulfur trioxide content in the flue gas, the higher the acid dew point temperature, the wider and more serious the corrosion range. The acid dew point in the flue gas can reach 140-160°C. In order to reduce the acid ...
