Boiler water quality issues
Thread Content
Could you please use water with a hardness of 0.0006mmol/l and an alkalinity of about 0.15mg/l, and can it be used directly as the inlet water of a low-pressure boiler (1.6MP) without adding any drugs? Can such incoming water maintain the alkalinity of the boiler between 6-16?
To add, can we now control boiler water alkalinity with reference to Industrial Boiler Water Quality (Draft for Comments) GB/T1576-2007?
The water quality of the boiler should meet the GB1576-2001 "Industrial Boiler Water Quality" standard. Whether the specific hardness and alkalinity indicators can meet the requirements and standards can be compared with the following. "Industrial Boiler Water Quality" GB/T1576-2007 is a draft for comments and has not been officially released for implementation. Therefore, the current industrial boiler water quality requirements should also comply with the GB1576-2001 "Industrial Boiler Water Quality" standard.
The water quality of the boiler should meet the GB/T1576-2008 "Industrial Boiler Water Quality" standard, which is the latest standard

Such as turbidity, PH value, dissolved oxygen, oil, total iron, conductivity and other indicators whether they meet the requirements. Softened water and demineralized water have different requirements. Hard enough. Basically, water treatment is required for safe operation.
If the water quality is okay, it is best to add some tank cleaning agent. If the evaporation volume is greater than 6 tons, it is recommended to add a deoxidizer and buy some raw materials to pour the tank cleaning agent into it. Generally, trisodium phosphate is used at a dose of 10 to 30PPM. It mainly reduces the hardness and forms soft calcium to control sewage discharge. For deoxidizer, add sodium sulfite 1# linlinlin628
