Desulfurization, denitrification and dust collector; Before starting the induced draft fan, add water to the dust collector. When using it for the first time, add water to the overflow pipe until it flows out. After turning on the induced draft fan, observe the smoke emission effect. If the smoke emission meets the standard, the induced draft fan does not carry water, and there is no abnormal vibration or noise in the induced draft fan and dust collector, the water level can be fixed and normal operation can be achieved; If black smoke is emitted or the standard is not met, raise the overflow pipe and continue adding water until it is qualified. If the induced draft fan carries water or the boiler's induced draft volume is too low, open the dust collector's discharge valve, slowly lower the water level of the dust collector, repeatedly adjust it to meet the composite requirements, fix the water level, and mark it on the water level gauge, indicating the low water level during operation and the high water level during shutdown.
When operating the desulfurization, denitrification, and dust collector, based on one's own experience, slightly open the inlet valve to ensure that the dust removal water consumption is equal to the inlet water volume, thus improving the quality of flue gas emissions. When the boiler is running, the dust collector should not discharge pollutants or add a large amount of water. If this is the case, the dust collector is prone to vibration, the induced draft fan may carry water, the chimney may suddenly emit black smoke, and the boiler furnace may suddenly experience positive pressure or smoke oscillation. Serious damage to equipment; If positive pressure or severe vibration occurs in the furnace, the furnace door may ignite or bulge, causing harm to surrounding personnel.
