55-ton biomass boiler dedusting, desulfurization, and denitrification equipment product introduction:
The primary function of the 55-ton biomass boiler dedusting, desulfurization, and denitrification equipment is to reduce the emissions of dust, sulfur dioxide, and nitrogen oxides during the combustion process of biomass boilers. Below is a detailed introduction to such equipment:
I. Equipment Composition
Dust collector：
FunctionCapture particulates from flue gas, such as dust and carbon black.
Common TypesPulse Jet Bag Filter. The bag filter removes particulates from flue gas through filter bags, featuring high dust removal efficiency, stable operation, and easy maintenance.
ConfigurationFor a 6-ton biomass boiler, a dust collector typically requires a certain area of filter bags to meet dust removal efficiency requirements.
Desulfurization Tower：
FeatureRemoval of sulfur dioxide (SO₂) from flue gas, preventing its排放 into the atmosphere and causing pollution.
Common TypesWet flue gas desulfurization tower, such as limestone-gypsum wet flue gas desulfurization tower. The wet flue gas desulfurization tower achieves desulfurization by reacting the absorbent liquid (e.g., limestone slurry) with sulfur dioxide in flue gas, producing by-products like gypsum.
FeaturesHigh desulfurization efficiency and mature technology, but with relatively high operating costs; requires disposal of by-products such as waste water and gypsum.
Denitrification unit：
SNCR Denitrification SystemBy injecting reductants (such as ammonia water, urea solution) into the furnace chamber, they react with nitrogen oxides in the flue gas under high temperatures to produce nitrogen and water. The SNCR denitrification system offers advantages like simple equipment, low investment, and low operating costs, although its denitrification efficiency is relatively lower.
SCR Denitrification DeviceUnder the action of catalysts, reductants (such as ammonia gas) react with nitrogen oxides in flue gas at lower temperatures, producing nitrogen and water. The SCR denitrification unit boasts high denitrification efficiency, strong adaptability, and stable operation. However, the equipment is complex and requires a significant investment.
FeaturesRemove nitrogen oxides (NOx) from smoke to minimize environmental pollution.
Common TypesSelective Non-Catalytic Reduction (SNCR) denitrification unit or Selective Catalytic Reduction (SCR) denitrification unit.
ConfigurationSelect the appropriate denitrification device type and configuration based on the boiler's combustion characteristics and nitrogen oxide emission concentration.
