Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
The ASME Boiler and Pressure Vessel Code details all the various calculations necessary to determine the MAWP of any pressure vessel.
This question can't be answered. It is unclear what you mean by back pressure. Maximum Allowable Working Pressure in a boiler is calculated using the rules for construction of high pressure boilers and construction of heating boilers in the ASME Code sections 1 and 8.
a designed pressure in a boiler is a little man who lives inside the boiler continually watching animated porn.
Boiler have minimum pressure 28 bar as per. Indian boiler act.so p c xan not call a boiler
lamont boiler is high pressure boiler & it'swork on high pressure at constant temprature
What you meant by this question is uncertain. If you are asking about the definition then Boiler steam pressure is the pressure developed by a water steam boiler, else if you are asking about the Rated boiler steam pressure then it is the safe operating pressure a boiler can operate, else if you are asking about Maximum boiler steam pressure then it is the maximum pressure that a boiler can produce with out failure.
15 psi
There are automatic boiler feeder and manual feeds and depending on the desired working pressure required that would determine the "SET" pressure of the feeder
Boiler feed pump's suction pressure be aprox. 15Kg/cm2 and discharge pressure be 180Kg/cm2. So the balancing line balance the pressure and protect the boiler feed pump. my quastion is that what is the working principal of balancing leak off
A low pressure boiler is any boiler 15 psi or lower
A leak on the return or supply lines and the automatic feeder is not working
Benson Boiler is a water tube high pressure boiler having forced circulation. It works on the principle that if the boiler pressure is raised to critical pressure (225 kg/cm^2) then there is no formation of steam bubbles Because the steam and water at this pressure will have the same Density. To achieve this water is fed to the boiler at critical pressure . At this pressure water will be directly converted to superheated steam as the latent heat at critical pressure is zero. Overall efficiency of plant is decreased as a lot of energy is consumed by feed water. Operating the boiler at a slightly lower pressure than the critical pressure efficiency can be increased. Thermal efficiency upto 90% can be achieved.

advanatages of high pressure boilers
500 MW Boiler is sub-critical Boiler which generates steam at pressure lower than the critical pressure ie below 221.2 kg/sqcm. where as the 660 MW boiler is super critical boiler which operates steam pressure above critical pressure.
