D.I. water in small steam boilers - Boiler and Pressure

In my typical application (humidification/steam boilers) we are constantly replacing the water as it boils off thus the water tends to "eat up" the metal. These type units use 316 SS. In a closed loop, the DI water will "get" some of the metal that the boiler is made of, but as it dissolves the water becomes less aggressive.

Hot-Water- and Steam-Boiler Water Treatment | HPAC Engineering

There are many types of boiler applications, the primary ones being hot water and steam. Hot-Water Applications. In hot-water applications, boilers typically operate within a stable closed-loop system in which the water chemistry is fairly constant. This means water is treated and stabilized for use during the initial fill of the system.

Changing Boiler from High Pressure to Low Pressure Question

In order to have the same energy at 15psi as at 160 the part of the equation that you need to change is the volume, i.e. bigger header pipe to "store" more steam or bigger boiler (a 10hp low pressure boiler is physically much larger than a 10hp high pressure boiler to store more volume of steam, therefore deliver the same energy as a physically

How does a steam turbine work in a closed loop?

The main source of energy supplied to the turbine comes from the heat added to the boiler to vaporize the water and discharge it at a high pressure. The drop in pressure from one end of the turbine to the other enables the flowing steam to cause the turbine blades to rotate and deliver electrical energy by turning a generator.
