Boilers operating at 15 psig steam pressure or lower, known as low-pressure heating boilers, are classified in SIC 3433.
YOU DON'T the ASME /NBBI codes have certain requirements regarding boiler manufacturing and a high pressure boiler can cause severe damage if it is not properly designed and routine maintenance performed ....
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.
Boiler pressure does not directly affect water temperature. Water temperature is primarily controlled by the thermostat setting on the boiler. However, excessive boiler pressure can lead to other issues such as leaks and inefficiency in heating the water.
Low alkalinity in boiler water can lead to increased corrosion of metal surfaces, as alkalinity helps to maintain a stable pH level. This can result in damage to the boiler components and decreased efficiency of the system. Additionally, low alkalinity can also lead to foaming and carryover in the boiler, which can cause operational issues and reduce the overall effectiveness of the boiler.
Add water to the boiler. You should have an automatic pressure reducing water make up valve, somewhere near the boiler. If it feeds directly into the boiler, make sure the boiler is cool when you add. Normal pressure on a cool boiler should be around 12 psi. The pressure will rise as the water is heated. You need a minimum of 1/2 psi for every foot of rise in the loop. So 12 psi in the basement will allow most systems to have a rise of appx 24 feet to the highest strip of baseboard. Remember, the pressure relief valve on the boiler lifts at 30 psi, so you need to stay well below that when the boiler is up to temperature.
I believe that is 15 PSI on a low pressure steam boiler
A low pressure boiler is any boiler 15 psi or lower
160psi

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.

Common boiler protections in a power plant include high steam pressure trip, low steam pressure trip, high furnace pressure trip, low water level trip, and flame failure trip. These protections help prevent dangerous situations such as overpressure, low water conditions, and flameout, which could lead to equipment damage or accidents. Regular testing and maintenance of these protections are essential for safe and reliable operation of the 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.
Depends on the situation! It may be needed at only a low pressure. Otherwise it may be the result of reduced heat input or of the input of cold feed-water.
