Xuecheng energy ammonia desulfurization project

Release time: September 3, 2020 | Focus on: eighty-three

The scale of flue gas desulfurization and denitrification device in heating system reconstruction project of Xuecheng Energy Co., Ltd. of Shandong weijiao group: 1 × 90t / h Mixed Combustion fluidized bed boiler supporting flue gas desulfurization and denitrification and ammonium sulfate system. Ammonia desulfurization technology is used to purify boiler tail gas. The design of the process system meets the local environmental protection emission requirements, i.e. ultra clean emission requirements, with flue gas emission concentration ≤ 5mg / Nm3; SO2 emission concentration ≤ 30mg / Nm3; NOx emission concentration ≤ 50mg / Nm3 (without catalyst).
SNCR + SCR combined denitration technology is adopted for denitration process. The denitration ammonia water tank is shared with the desulfurization system, SNCR process is preferred for denitration treatment, SCR is set at the reserved position of boiler flue, and catalyst is not installed.
The desulfurization process system is arranged behind the boiler induced draft fan, with a single boiler and single tower, and a set of desulfurization absorption system is set. After desulfurization and purification, the flue gas is discharged through the chimney at the top of the desulfurization tower.
