Characteristics of boiler feedwater - Lennte
A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure.

Boiler Efficiency and Steam Quality: The Challenge
For example, if a process of which steam consumption is only 5% of boiler output is turned on rapidly (such as with an on-off valve), the system demand can easily increase by 15% or more until the process reaches a steady state of operation. When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly.

Gauge pressure is pressure in pounds per square inch above atmo-spheric pressure which is 14.7 pounds per square inch absolute. Gauge pressure (psig) plus 14.7 equals absolute pressure. Or, absolute pressure minus 14.7 equals gauge pressure. Pressure/Temperature Relationship (Columns 1, 2 and 3). For every pressure of pure steam there is a

Cleaver-Brooks | Reference Center | Boiler Basics | Ste
High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. Steam and hot water boilers are defined according to design pressure and operating pressure.

Boiler (power generation) - Wikiped
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
