What is Acid Phosphate Corrosion? - Definition from …

Phosphate buffers the boiler water, reducing the chance of large pH changes due to the development of high caustic concentrations. Excess caustic combines with disodium phosphate and forms trisodium phosphate. Sufficient disodium phosphate must be available to combine with all of the free caustic in order to form trisodium phosphate.

How To Clean Your Steam Boiler - Cambro

Instead of trisodium phosphate, you could also use sodium hydroxide or sodium carbonate. Step 2: Turn up the heat of your steam boiler until it is about 80 degrees Celsius; leave it like this for around 2 hours, making sure that it doesn't start producing steam (this shouldn't be too difficult, as water doesn't actually boil until it reaches about 100 degrees Celsius).
