High Salinity Of Boiler Water Remedy

Common issues found on Boiler feed water like corrosion

Apr 12, 2020 · The boiler manufacturers stipulate a maximum allowed salinity of the boiler water (as a rule at 0.4° Be = 4000 mg salts dissolved per litre). If this value is exceeded, there is a risk of normal bubble size being prevented; larger bubbles will be produced and the turbulence in the water surface will ncrease and cause foaming.

Foaming and Carryover are caused due to high dissolved solid and caustic alkalinity in combination with leakages, load changes and organic matter ( oil). Control of boiler-water chemistry, before and after the water enters the steam generating system, is vital to efficient operation, acceptable maintenance costs, and satisfactory equipment

What Is Water Demineralization and How Does It Work?

Feb 19, 2018 · Demineralization generally results in almost complete removal of minerals, and is thus typically reserved for applications requiring higher level of water purity, such as feed or makeup water for high pressure boilers, rinse water for food and beverage industries, or process streams used in electronics manufacture, for example. For fresh water

Boiler feedwater - Wikipedia

History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was "blown down". It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.

Feed water treatment - Marine steam boilers and boiler

This is controlled by (1) proper boiler design to eliminate "dead pockets" and (2), the use of feed water treatment to render the boiler water slightly alkaline. "Sea water" contamination occurring while an engineering plant is operating close to beaches, or in harbours and rivers, will introduce silicates into the boilers.

Feed-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

Mar 23, 2010 · In steamships boiler feed water consists of condensate returns along with make-up feed water. The testing of boiler feed water is imperative to prevent many conditions which are detrimental to safe, efficient boiler steaming. These main culprits are high acid and oxygen content causing corrosion and pitting inside the water tubes and boiler internals. High alkalinity and solids promote scaling

Sep 15, 2014 · Slightly saline water: 1,000 ppm – 3,000 ppm. Moderately saline water: 3,000 ppm – 10,000 ppm. Highly saline water: 10,000 ppm – 35,000 ppm. Seawater is about 35,000 ppm salt. Salt enters waterways from contact with rocks containing soluble minerals, which is how even "fresh" water far from oceans can become especially salty.

Brackish Water Treatment System for High Salt Water

Brackish water treatment plant is used to treat water TDS between 5000ppm to 15000ppm. It's more effective than normal water treatment to lowered down the TDS and make sure the RO membrane is in good condition. On the other hand, it is much more economic than seawater desalination plant. It is the best choice for borehole water or other brine
