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.
Boiler have minimum pressure 28 bar as per. Indian boiler act.so p c xan not call a boiler
when the pressure increases over the maximum allowable working pressure of the vessel, the valve will open to protect against overpressure.
lamont boiler is high pressure boiler & it'swork on high pressure at constant temprature
The IBR (Indian Boiler Regulations) formula for boilers depends on the type of boiler and its capacity. In general, the formula calculates the minimum safe working pressure (PS) of a boiler based on its heating surface area and capacity. The formula is PS = (W x H^2) / (500 x A), where PS is the safe working pressure, W is the weight of water in the boiler in kg, H is the heating surface area in square meters, and A is the capacity in liters.
A low pressure boiler is any boiler 15 psi or lower
The maximum allowable working pressure for a low pressure steam boiler is typically up to 15 psi (pounds per square inch). This indicates the highest pressure level at which the boiler can operate safely without the risk of failure or damage. It is important to adhere to the manufacturer's specified limits to maintain the boiler's safety and functionality.
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
Boiler steam pressure refers to the force exerted by steam within a boiler, measured in units like PSI or bar. This pressure level is essential for efficient energy transfer and controls the temperature and flow of steam in heating systems, turbines, and other applications.
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.
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.
