Biomass Power Plant SNCR Denitrification Equipment
In the field of biomass power generation, the SNCR denitrification equipment is an effective technology for controlling nitrogen oxides (NOx) emissions. The following introduction covers aspects such as the equipment's principle, applicable scenarios, and its advantages and characteristics:
1. SNCR Denitrification Technology Principle
SNCR (Selective Non-Catalytic Reduction) denitrification technology achieves denitrification by injecting reductant (such as ammonia water or urea solution) into the high-temperature furnace area (usually 850℃～1100℃), where it reacts chemically with NOx in the flue gas to produce nitrogen (N₂) and water (H₂O). This method does not require a catalyst, making it cost-effective in terms of equipment investment and operation, and is suitable for small and medium-sized biomass power generation boilers.
2. Applicability to biomass power plants
Biomass power plants commonly use equipment such as chain furnaces and circulating fluidized bed boilers to burn biomass fuels (like straw, wood chips, and garbage) to generate steam for electricity. Due to the high nitrogen content in biomass fuels, NOx emissions are easily produced during combustion. SNCR denitrification equipment can effectively control NOx emissions from biomass power plants, meeting environmental protection requirements.
3. Advantages of SNCR Denitrification Equipment in Biomass Power Generation
Low investment costCompared to SCR (Selective Catalytic Reduction) denitrification technology, SNCR requires no catalyst, resulting in lower equipment investment and operating costs.
Wide range of applicationsSuitable for small and medium-sized biomass boilers, especially for the denitrification technology transformation of old units.
Flexible operations: The dosing of reductant can be adjusted based on boiler load and NOx emission concentration, offering high flexibility.
No secondary pollutionSNCR technology does not produce ammonia escape or aerosol secondary pollution issues.
