Section Two: Key Modules of SNCR/SCR Denitrification System
The SNCR/SCR denitrification system is composed of multiple key modules, which collectively ensure the system's efficient and stable operation.
Compressed Air ModuleEquipped with a variable frequency screw air compressor, configured for gas production based on ammonia/urea usage, and features an air storage tank to ensure stable system operation.
Ammonia Unloading ModuleSupports tank truck-mounted卸氨泵 or on-site installation of ammonia/urea卸料泵 to ensure the reductant is smoothly unloaded into the storage module.
Storage ModuleThe ammonia/urea storage tanks are made of 304 stainless steel, with walls designed at a thickness of 5~10mm, providing a total storage capacity to meet the daily consumption for 7 days under full boiler load.
Conveyance ModuleEquipped with an ammonia/urea conveying system, featuring a 200% flow design, and equipped with a filtration system to prevent clogging, ensuring uniform delivery of the reductant.
Online Dilution Metering and Distribution ModuleEach furnace is equipped with a metering and blending module, controlled by a flow meter to regulate the mixture ratio of diluent water and reducing agent, ensuring uniform喷射.
