In addition, hardness salts can precipitate from the boiler water to form sludge and eventually scale, which deposits on the internal surfaces of the boiler. The result: a serious loss of boiler efficiency, and possibly boiler failure.

Firetube Boiler Design, Construction & EngineeringSummary • The firetube boiler is a versatile package suitable for a plethora of applications including heating and process • Typical size range is 100 –2500 HP • Pressures to 350 • Construction follows ASME code Sections I & IV and includes close 3rd party inspections • There are both dryback & wetback horizontal firetubes with each having advantages and disadvantagesTHE BASICS OF BOILER WATER CHEMISTRY - Cleaver-Brooks• Flow rate in boiler or feed water. ASME Guidelines: Broken down by feed water and boiler water, and then by firetube. and watertube boilers. 37 TOLERANCES ARE BASED ON PRESSURE & TEMPERATURE Water Constituent Tolerance: 0-300 operating psig: FIRE TUBE BOILER. 43.

Boiler – Fundamentals and Best PracticesFire Tube Boilers Water Tube Boilers Waste Heat Boilers Low Pressure Systems Medium to High Pressure Systems • British Standard BS2486:1997 • ASME Guidelines* 1994 Consensus on operating practices for ASME Boiler Feedwater QualityBoiler Feed Water and Boiler Water - EWT Water TechnologyEN 12952-12 / Water-tube boilers – Requirements for boiler feed water and boiler water quality; EN 12953-10 / Shell boilers – Requirements for boiler feed water and boiler water quality; national codes and standards: BS 2486 / Recommendations for Treatment of Water for Steam Boilers and Water Heaters (United Kingdom, obsolete) TRD 611 Characteristics of boiler feedwater - LenntechFeed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica
