corrosion problems because of the acidity as well as the other water treatments may not work if the alkalinity is out of target
A low-pressure boiler works by generating steam at a pressure lower than 15 psi (pounds per square inch). Water is heated in the boiler and turns into steam, which is then used for various applications such as heating or powering machinery. Low-pressure boilers are commonly used in buildings for heating systems and hot water supply.
Making up feed with water having low PH. Feed water getting contaminated with sea water, greese, fatty/fuel oils, CO2, 02 can cause water to become acidic leading to boiler corrosion as well as redusing it PH value. Lot of leakage will also cause more make up water and if regular blow down is not carried out, will cause increase in total disolve solides, thus reducing PH. Also if boiler water treatment is not carried out properly can result in drop in PH.
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 ....
The water tube boiler forces water through tubes and heats these tubes from the outside. This is done in a combustion boiler, or in the steam generator of a pressurized water nuclear reactor. It could even be done in a thermal vent in a geologically active area. The heat penetrates the tubes and increases the thermal energy of the water in the tubes and turns it to steam. The steam is sent to do work, as in a turbine. The steam loses thermal energy as it passes through the turbine, and it eventually exits the turbine as low energy steam. It is then dumped into a condenser. Here the "last little bit" of the steam's energy is removed by the cooling water passing through tubes in the condenser, and the steam is turned back into water. The water is them pumped back through the water tubes in the boiler or steam generator to repeat the cycle. The
as the boiler drum is cylindrical in shape due to low stress concentration and in both end the diameter will be less.so for easy entry into the drum for a man the drum man hole is elliptical in shape.
Phosphate is injected into boiler feed water to control scale formation and corrosion inside the boiler system. Phosphate forms a protective layer on metal surfaces to prevent scale buildup and reduces the risk of corrosion, improving the overall efficiency and longevity of the boiler.
Add rain water this has very low alkalinity
Improperly sanitized water or excessive rainfall can cause a low total alkalinity level in your pool. Low total alkalinity can cause pool staining, itchy and burning eyes and skin, and corrosion of metal parts in the pool.

Low level boiler water can be caused by leaks in the system, improper operation of feedwater pumps, or malfunctioning control valves. It can lead to a reduction in heat transfer efficiency and potentially damage to the boiler system if not addressed promptly. Regular maintenance and monitoring of the boiler system can help prevent low water levels.
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.

add some form of alkalinity booster for sure. bring it too about 110ppm, chlorine has a naturally high pH, but the higher alkalinity addition will stop acidic compounds from attacking the pH any further. depending on how low the pH is though you may have to add a pH booster, take your water into a pool shop for an in depth water analysis.
fire tube & water tube . high pressure and low pressure. low capacity and high capacity.
For a while IF the boiler has an automatic low water cut off and other safety devices but if any fail you will have a melt down and an explosion
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.
