How to clean the boiler with trisodium phosphate?
If the boiler is not cleaned for a long time, a large amount of scale will be generated. The harm of scale on the boiler is not only an impact on the thermal conductivity. In severe cases, the superheater of the heated surface may burst or overheat. Natural water is an aqueous solution of electrolyte, which is prone to electrochemical corrosion in contact with metals. It is known that sodium hexametaphosphate is used for water softening when using a boiler. So how to clean the boiler with trisodium phosphate ? Boiler cleaning method: 1. Flush Condenser---Before flushing the water supply system, the condenser, hot well, deaerator, and water supply tank should be manually cleaned with 2% trisodium phosphate (Na31PO4.12H20) solution, and then rinsed with ordinary water system. It is best to use demineralized water for the formal flushing of the system. The cycle power for flushing is provided by the condensate pump, and the condenser hot well is used as a water storage container. In...
