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.

What is the difference between steam boiler and pressure vessel?
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
What is the function of back pressure valve in Boiler feed pump?
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
What is a design pressure in a boiler?
a designed pressure in a boiler is a little man who lives inside the boiler continually watching animated porn.
How a boiler is different from kettle or pressure cooker?
Boiler have minimum pressure 28 bar as per. Indian boiler act.so p c xan not call a boiler
How is boiler efficiency calculated?
Boiler efficiency is calculated by determining the steam value per hour and dividing it by the amount of fuel which is consumed per hour. By doing this one can determine the efficiency of a boiler.
Boiler steam pressure?
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.
How many pounds of pressure does low pressure boiler operate on?
A low pressure boiler is any boiler 15 psi or lower
How does a back boiler work scientifically?
A boiler works by heating water in an enclosed space. The expansion of water molecules as it transforms from a liquid state into a gaseous one causes the boiler to generate a vast amount of pressure. This is generally the science behind a back boiler.
What is the difference between steam boiler and pressure vessel?
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
What is the feed check valve of boiler?
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
Advantage of high pressure boiler over high pressure boiler?
advanatages of high pressure boilers
What is the function of back pressure valve in Boiler feed pump?
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
Why boiler is in vaccumed condition?
Because you forgot to open the vent when the pressure dropped below 15 psig. A boiler under vacuum will suck in its handholes and manholes, and they might start leaking when pressure is put back on them. weakened boiler parts can fail as well.
What is difference between 500MW boiler 660MW boiler?
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.
What is the working principle and construction of lamont boiler?
lamont boiler is high pressure boiler & it'swork on high pressure at constant temprature
What is a design pressure in a boiler?
a designed pressure in a boiler is a little man who lives inside the boiler continually watching animated porn.
