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.

Why boiler drum steam pressure always different from boiler main steam line pressure?
Due to pascals law
Why is to safety valve mounted on boiler drum?
the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.
What the difference between extraction and bleeding in steam turbine?
bleed is amount of steam output from turbine through pipe and exit from final stage of turbine . this bleed enter to feed water heater (low and high) and deaereator to increase unit efficiency or rather bleed is the amount of steam drained out of the steam turbine during the expansion of steam and this rejected heat energy is used to heat the feed water supplied to the boiler...........
What steps needs for start a steam turbine from cold conditon?
steam turbine cold start up list:
Why boiler drum vents close at 2 kg pressure while strting?
in 2kg we get proper venting of unsoluble gases as well as air and ultimate answer is it is easy to operate at 2kg.if we operate at much pressure it is difficult and steam venting is more
Why boiler drum steam pressure always different from boiler main steam line pressure?
Due to pascals law
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 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 does the steam boiler do?
Boils water to create high pressure steam.
What is the highest pressure safety valve allowed on a low pressure boiler?
I believe that is 15 PSI on a low pressure steam boiler
How boilers are classified?
A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and process application. A high pressure steam boiler can be named as Power Boiler, in which design and construction rule following to rules of ASME Boiler and Pressure Vessel Code Section I - Power Boiler.
What can happen if you had a sudden drop on boiler steam pressure without a corresponding drop in boiler water temperature?
BOILER EXPLOSION- Caused by a sudden drop in pressure (failure on the steam side) without acorresponding drop in temperature.
What the inside of steam boiler?
"What the inside of steam boiler?" Would you like to know: with no water and steam, construction, under steam conditions, high loads, high TDS, Low pressure.
What does psi mean on a pressure trol on a steam boiler?
psi is Pounds per Square Inch, and is a measure of the pressure inside the boiler.
What is the use of the boiler?
to cook food using steam pressure of course
A low pressure steam boiler has a maximum allowable working pressure of up to?
15 psi
What is the explanation for the working of a benson boiler?
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.
