Waste acid treatment unit: Why is water added during the heating-up of the waste heat boiler?
Thread Content
As the title suggests, is it to prevent the steam drum from being damaged or to avoid excessive temperatures? The valve for purification has been closed; the vent valve is open. Everyone, **please help out**
During the furnace drying process, the waste heat boiler is heated using residual heat to prevent it from drying out; at the same time, a chemical dosing system is activated. Once the furnace drying is complete, the waste heat boiler also operates normally again!
