Principle of boiler desulfurization and denitrification

The working principle of desulfurization and denitrification tower refers to reducing the generated NOX to N2, so as to remove NOX from flue gas. According to the treatment process, it can be divided into wet nitrogen removal and dry nitrogen removal. It mainly includes: acid absorption method, alkali absorption method, selective catalytic reduction method, non-selective catalytic reduction method, adsorption method, ionic body activation method and so on. Some researchers at home and abroad have also developed methods to treat NOX waste gas by microorganisms.
