One major perk of purified tannin technology is that it allows boilers to be operated at higher cycles of concentration – even higher than ASME guidelines. This allows boilers to run more efficiently and reducing fuel and makeup water usage to significantly cut costs over time when compared to other boiler treatment options.
Boiler cleaning and treatment can extend the lifespan of your equipment and help your business thrive.

water in the boiler or cooling water system to reduce concentration of dissolved and/or suspended solids. Boiler Water - A term construed to mean a representative sample of the circulating boiler water, after the generated steam has been separated, and before the incoming feed water or added chemical becomes mixed with it, so that
Boiler Feed Water Treatment for Industrial Boilers and Power Plants Boiler Water Treatment removes impurities from water outside the boiler in order to minimize scaling. Scaling and corrosion due to poorly treated water are mostly faced problems in steam boilers.
Over 85 years of diverse industry experience, our commitment to develop innovative boiler water treatment technologies continues today. Chemical treatment coupled with 3D TRASAR technology provides comprehensive boiler water treatment solution mitigating scale and corrosion of the boiler system.

The boiler manufacturer should give you guidelines. The requirement for makeup treatment will depend somewhat on your water supply analysis, the boiler application, and the manufacturer's guidelines. As a minimum, you need zero soft water, something that is obtainable with a good quality water softening unit.
ASME Guidelines: Broken down by feed water and boiler water, and then by firetube. and watertube boilers.

guidelines and not strictly applicable for all situations. Exceptions may be taken depending on operating conditions and the treatment programs employed. Examples are boiler water alkalinities and silica. In some lower pressure systems employing softened, high alkalinity makeup water, total alkalinities may be allowed as high as 1200 ppm when utilizing a specific boiler water antifoam and conducting a recommended embrittlement study.

As a minimum, you need zero soft water, something that is obtainable with a good quality water softening unit. The 600 psi rating is close to the breakpoint between using a deimineralizer or water softener. The link below provides some information as to the ASME guidelines:
Boiler Water Treatment Proper treatment of make-up waste and boiler water is necessary to prevent scale, or other deposits, and corrosion within the boiler. The absence of adequate external and internal treatment can lead to operational upsets or total boiler failure.
It was prepared by the Water Technology Subcommittee of the ASME Research and Technology Committee on Water and Steam in Thermal Systems and provides recommendations for sampling and monitoring required to maintain the suggested water chemistry limits outlined in:
Drift - Water lost from a water-cooling tower as liquid droplets entrained in the exhaust air, units: kg per hour or percent of circulating water flow. Feedwater - The water supplied to a boiler to make-up for losses. Floc - Any small, tufted, or flakelike mass of matter floating in a solution, e.g., as produced by precipitation.

Boiler Blowdown Standards: Boiler blowdown is primarily used to control dissolved solids in boiler water, and to remove loose scale and sediment contaminants. However, the frequency of blowdown depends solely on specific boiler and steam system operating conditions. This frequency can be specified by a local chemical treatment company.
purity is specified in NAVSEA S9086-GX-STM-020, Section 220, Volume 2, Boiler Water/Feedwater Test and Treatment , and PACNAVFACENGCOM P200, Shore-to- Ship Steam and Feedwater Manual for Naval Facilities .
American Society of Mechanical Engineers (ASME) guidelines should be consulted for a full discussion of chemical control variables, including dissolved oxygen, pH, conductivity, iron, copper, and hardness (ASME guidelines are contained in the Appendix section).
There is also a recommendation in each table for fuel fired boilers operating below 900 psig (6.21 MPa): the hydroxide alkalinity concentration should be individually specified by a qualified water treatment consultant at a concentration high enough to ensure silica solubility. Ì 6.6 Alkalinity The maximum boiler water alkalinity values given in Tables 1 through 4 and 6 are specified as total or methyl orange alkalinity, expressed in ppm (mg/l) CaCO3 for all boilers operating below 900 psig
Water Hardness is the primary source of scale in boiler equipment. Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.

1. External treatment: Treatment of water—makeup, condensate, or both, before it enters the boiler, to reduce or eliminate chemicals (such as hardness or silica), gases or solids. 2. Internal treatment: Treatment of the boiler feed water, boiler water, steam, or condensate with corrective chemicals. 3.

internally with a variety of treatment chemicals. The boiler water should be maintained at pH 11. This may require an addition of alkaline if the water is not soft. A chemical called a sludge conditioner can be added to treat the solids so that they drop out (precipitate). These treated solids then must be removed from the boiler by blowoff.
Fire Tube Boilers. Also referred to as smoke tube boilers, shell boilers, package boilers Multiple gas paths - 2, 3 and 4 pass Internal furnace or fire box as the 1st pass Dry back or wet back design Single fuel or dual fuel design Little or no steam separation equipment.
