First, start filter bag 1, the start of raw materials use fuel oil boiler flue gas after combustion temperature up to 150-175 ℃ or higher; 2, check each chamber inlet valve is adjusted manually opened; 3, in order to open the fan, at least to ensure that there are four rooms online, in order to ensure adequate flue gas channel; 4, only when all the rooms online and the outlet temperature exceeds 140 ℃, before they can start the boiler combustion; 5, in the initial startup process, filter pressure drop due to the amount of wind and dust is relatively small and low, automatic cleaning mode is automatically delayed until stable operation is not cleaning, the cleaning mode is best at this time good use differential pressure control, differential pressure rises to know the thickness of the ash layer, in which case you can begin cleaning dust; 6, start the initial filter, the filter bag surface does not form a complete layer of pink cloth, a small amount of fine dust will escape the plumes may be formed in the chimney. Second, the bag filter operation 1, after the start, will form a cloth bag surface layer of powder, dust will be offline cleaning procedures. 2, in general, the best display performance dust removal system is the pressure drop. Especially single filter pressure drop of the filter chamber bag is the best show condition, the pressure drop of a sudden increase or decrease means that the bag clogging, leakage, the valve does not move, hopper cleaning system failure or fouling excessive. 3, in the protection of the bag, the pressure drop for each filter chamber may not exceed 2000Pa.
