Small Biomass Fluidized Bed Boiler Desulfurization and Denitrification Equipment

     Small Fluidized Bed Boiler Desulfurization and Denitrification Equipment
     For small fluidized bed boilers, the following is a detailed introduction to their desulfurization and denitrification equipment:
     I. Equipment Overview
     The small biomass fluidized bed boiler desulfurization and denitrification equipment is a specialized system designed to treat sulfur dioxide (SO2) and nitrogen oxides (NOx) in the flue gas of small fluidized bed boilers. Utilizing advanced desulfurization and denitrification technologies, this equipment converts harmful substances in the flue gas into harmless compounds, ensuring compliant emissions.

      II. Working Principles
     1. Desulfurization Principle: Typically employs wet desulfurization technologies, such as limestone-gypsum or ammonia methods. When flue gas passes through the desulfurization tower, it fully contacts and chemically reacts with desulfurizing agents (e.g., limestone slurry, ammonia water), producing harmless substances like sulfates.
     2. Denitrification Principle: Primarily uses SNCR (Selective Non-Catalytic Reduction) or SCR (Selective Catalytic Reduction) technologies. SNCR involves injecting reducing agents (e.g., urea, ammonia water) into the boiler flue or furnace to reduce NOx into nitrogen and water. SCR, on the other hand, utilizes catalysts to facilitate the reduction reaction between reducing agents and NOx, also producing nitrogen and water.
