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).

Boiler water - Wikipedia

Many large boilers including those used in thermal power stations recycle condensed steam for re-use within the boiler. Steam condensate is distilled water, but it may contain dissolved gases.A deaerator is often used to convert condensate to feedwater by removing potentially damaging gases including oxygen, carbon dioxide, ammonia and hydrogen sulfide.
