allowable limit of sulphur in boiler Agent water

Industrial Water Analysis - Lenntech

Aug 23, 2019 · Sulfur-reducing bacteria, which use sulfur as an energy source, are the primary producers of large quantities of hydrogen sulfide. These bacteria chemically change natural sulfates in water to hydrogen sulfide. Sulfur-reducing bacteria live in oxygen-deficient environments such as deep wells, plumbing systems, water softeners, and water heaters.

Indian Standard: SULPHUR—CODE OF SAFETy

Proper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper

Boiler Water. The boiler water itself must be dosed in order for the boiler to run efficiently and safely. A chemical imbalance can lead to corrosion and damage to the system and this damage can ultimately lead to boiler failure and injury. Boiler water analyses are basically aimed at keeping the parameters within established limits. Tests include

Limiting the maximum Sulphur content of the fuel oils.

This implies that a sulphur content of up to 0.53% may be accepted as compliant when testing the "In-use" sample and the "On board" sample. This is to ensure that ships are not unjustly penalized for marginal excess in sulphur content beyond their control. However, the fuel ordered/delivered to the vessel must still not exceed 0.50%.
