Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig.

The Importance of Boiler Water and Steam Chemistry

Often, for low pressure building or process heater steam, only a maximum moisture content is specified. This may be as high as 0.5% or as low as 0.1%. Conversely, some turbine manufacturers specify steam condensate maximum cation conductivity, pH, and maximum concentrations for total dissolved solids, sodium and potassium, silica, iron and copper.

Steam Heating Boilers Operating Pressure Settings Residential steam heating systems are almost always designed to operate at very low pressures, typically around 0.2 psi to a maximum of 0.5 psi - that' s 1/2 of one psi. Click to enlarge and you can see the actual pressure settings on the steam boiler control shown at left.

Lower Pressure Operation of Boiler than Designed

Boilers are designed for both constant pressure operation and sliding pressure operation. In constant pressure operation the boiler superheater outlet pressure is designed to be maintained constant from as low as 40% of the rated maximum continuous load.

Residential Steam Boiler Basics - The Spruce

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

IMO, if you are installing a 25 year plastic gasketed steam boiler use the press fittings for the near boiler piping.. They will probably all fail about the same time. If you are installing a 40 to 50 year heavy duty cast iron boiler and especially a steel boiler ( 100 years life?), don't use the press fittings.

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

For example, dry saturated steam at 60 bar g would have to be reduced to approximately 10.5 bar g to produce dry saturated steam. Any less of a pressure drop will produce wet steam, while any greater pressure drop would produce superheated steam. Equally, the state of the supply steam at any pressure will influence the state of the throttled steam.

Pressure Steam - an overview | ScienceDirect Topics

The advances in steam pressure and temperature led to the development of the reheat cycle, where steam is exhausted from the high-pressure turbine at reduced pressure and temperature and is then returned either to a section of the boiler or to a separate boiler to be reheated. Once reheated, the steam is sent to the low-pressure boiler.
