The flue gas treatment of two 150t/h boilers of Shandong Asd Technology Co., Ltd. adopts the ammonia desulfurization process, adopts a single furnace and a single tower, and sets up two sets of desulfurization absorption systems. After desulfurization and purification, the flue gas is discharged through a separate chimney.
The design of the process system must meet the requirements of flue gas desulfurization in the case of pure coal combustion in the boiler (design and verification coal type), and the boiler combustion coal mixed with process tail gas, and meet environmental protection emission requirements, that is, ultra-clean emission requirements. Smoke emission concentration ≤ 5mg/m3; NOX emission.
