I want to know the reason for very low D.P in Kiln bag house in cement plant… In a particular date the temperature has reduced 50C (for 8 hrs) and the SO2 reached to 580 mg/Nm3 for 2 hrs.And in the same date the D.P measured as 15 mm Wc average for 8 hrs. I couldn't understand the reason for this very low D.P .. Can you explain please… Replyconsumption stems from steel making, flue gas desulfurization at coal-fired electric power plants, construction, pulp and paper manufacturing, and water purification. Lime is produced in a two or three step process: stone preparation, calcination, and hydration. Calcination is the process by which limestone, which is mostly calcium carbonate ...Read More
