Steam generator flue gas treatment method

As a common energy equipment, steam generators play an important role in promoting economic development. However, the harmful substances contained in the flue gas of steam generators pollute the environment and threaten the health of residents. The steam generator flue gas treatment method is to purify the steam generator flue gas so that the emissions meet the standards. So what are the methods for treating steam generator flue gas? Nobeth is a brand that provides a complete set of steam generator solutions. It also has in-depth research on steam generator flue gas treatment methods. It is summarized here and hopes to help everyone.

According to relevant regulations on boiler air pollution, the current industrial steam generator flue gas treatment problems are mainly sulfides, nitrogen oxides, and smoke dust, and different steam generator flue gas treatment methods need to be adopted respectively.

1. Desulfurization of steam generator flue gas treatment methods
According to the type of desulfurizer, the steam generator flue gas desulfurization methods include the calcium method based on CaCO3 (limestone), the magnesium method based on MgO, the sodium method based on Na2S03, and the ammonia method based on NH3. , organic alkali method based on organic alkali. Among them, the most commonly used commercial technology in the world is the calcium method, accounting for more than 90%.

2. Steam generator flue gas treatment method: denitrification
Denitrification technologies mainly include low-nitrogen combustion technology, SNCR denitrification technology, SCR denitrification technology, ozone oxidation denitrification technology, etc. Different boilers can use different boiler flue gas treatment methods.

3. Steam generator flue gas treatment method: dust removal
The particulate smoke and dust in the combustion exhaust gas of steam generator furnaces are treated with industrial steam generator dust collectors. Commonly used industrial steam generator dust collectors include gravity sedimentation dust collectors, cyclone dust collectors, impact dust collectors, centrifugal water film dust collectors, etc. As environmental protection requirements become increasingly stringent, the application of bag dust collectors and electrostatic precipitators will gradually increase. At present, the industrial steam generator dust collectors that are widely used in industrial steam generators and can meet the requirements of smoke and dust emission standards are mainly multi-tube cyclone dust collectors and water film dust collectors.
