Boiler projects burn natural gas to produce steam. What are the types of energy consumption of the project?

Steam is produced by water, so it is needed. Water quality affects boiler life, so a set of softened water is needed. The production of softened water is inseparable from the consumption of salt and resin. Boiler make-up water needs high-pressure pump, and water pump operation needs consumption. Finally, fuel (natural gas) is indispensable.

Summary: water, electricity, gas, salt, resin. Generally speaking, that's it. If there are higher requirements for steam quality, there will be other expenses.
