Some Criteria for Choosing a Steam Boiler for a Microbrewery

A high pressure steam boiler is a Section I boiler and they are usually stamped for 100, 125 or 150 PSI. There is a direct correlation between steam pressure and temperature. 10 PSI steam equates to 240o F (115o C)and 15 PSI steam = 250o F (121o C). 12-14 PSI is where most low pressure boilers operate.

Steam and Condensate - A basic overview of a steam system

General Boiler Information. Superheat is a term that refers to higher temperature steam, as a result of a second special steam heat exchanger in the boiler that allows steam pressure to increase, thereby taking on more BTUs (in excess of 500 psi is typical of superheat). Superheated steam is : Robb Luther[PDF]Industrial Combustion Boilers - IEA-ETSAPhttps://iea-etsap.org/E-TechDS/PDF/I01-ind_boilers-GS-AD-gct.pdfSince the first boilers were used in the 18th century, the design of boilers has evolved so as to increase efficiency as well as steam pressure and temperature. In the United States, the energy consumption of industrial boilers accounts for 37% of total energy use in the industrial sector.

Steam vs. Hot Water Pros vs. Cons - centerpointenergy.com

 A Boiler is a closed vessel in which water, under pressure, is transformed into steam by the application of heat. In the boiler furnace, the chemical energy in the fuel is converted to heat and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner.

What You Need to Know About Residential Steam Boilers

The steam boiler is an old convection heating technology dating back over 200 years and is commonly found in older homes. Because steam boilers operate at a higher temperature than hot water boilers they are inherently less efficient than their hot water cousins. They are also a lot more finicky to operate.
