Installation and construction of desulfurization flue gas system equipment in a power plant programme
1.1 Project overview The flue of desulfurization project is composed of original flue and clean flue, and each unit is equipped with its own independent original flue and clean flue system. The flue gas process is as follows: the flue gas passes through the original flue from the boiler flue behind the induced draft fan, enters the absorption tower after being boosted by the booster fan, enters the clean flue through the demister after flue gas desulfurization in the absorption tower, and is discharged to the flue and enters the atmosphere through the chimney. Desulfurization flue consists of clean flue and original flue; The installation method is to install the single piece by butt welding on the site of the segmented transportation road. The flue support shall be installed in bulk, aligned and accepted separately. Booster fan is mainly composed of inlet box, bearing box, hub, impeller housing, blade, diffuser, intermediate shaft, motor, blade adjustment and control mechanism, hydraulic oil station, lubricating oil station, seal fan, oil and water pipeline, coupling protective cover, flexible connection and other components
