The flue gas discharged from the boiler passes through the SCR for highly effective denitration. After going through the outlet of air pre-heater.
The smoke plume can be eliminated mainly from two aspects: reducing the absolute and relative moisture content of flue gas.
Limestone/lime/carbide slag is used as desulfurization absorbent, and the limestone/lime/carbide slag is crushed into powder, mixed with water, and stirred to form absorption slurry.
Does not have secondary pollution, waste water, waste residue, and carbon dioxide emission.
SNCR refers to Selective Non-Catalytic Reduction, which uses NH3, urea and other matters as the reducing agent.
SCR denitration uses catalyst to make NOx in the flue gas start reduction reaction with ammonia, the reducing agent, -to generate nitrogen and water, thus reducing NOx emission.
SNCR+SCR combined denitration technology is a novel, efficient and technically mature process that combines the efficiency of the SCR technology and economical efficiency of the SNCR technology.
Dust particles in the dust flue gas are filtered by filtering materials, the coarse particles are mainly collected through inertial impaction while the fine being collected through diffusion.
"SNCR + semi-drying process (Ca(OH)2) + drying process (Ca(OH)2) + activated carbon injection + bag dust removal + SCR denitration system" combined flue gas cleaning process.
The flue gas of glass furnace flows into a waste heat boiler and out of the high-temperature side of the 350 ℃ - 380℃ section of the exact boiler.
The sintering flue gas flows into a high-temperature dust collector to remove particles and a desulfurization plant to remove sulfur dioxide.
