scale and sludge in steam boiler

Scale and Corrosion Inhibitors | Boiler Phosphate Treatment

Scale Inhibitors & Sludge Conditioners. Scale is caused by the accumulation of hardness salts in the boiler water which, if not removed can cause localised overheating, reduced heat transfer efficiency, and in severe situations tube failure. Hardness salts can either be removed before they enter the boiler system or they can be treated inside

What Is Boiler Sludge? | How to Clean a Steam Boiler System

Aug 14, 2019 · What is Boiler Sludge? Just what is boiler sludge, you ask? Essentially, its nothing more than the deposits found in water building up within the boiler tank over time. These deposits may consist of minerals, oils, and other matter. Sludge can stick to the boiler walls and continue to grow in size over time, causing clogs and other issues.

Boiler Scale Inhibitors | ChemTreat, Inc.

The formation of scale and sludge can cause tube failures, restrict circulation, reduce system efficiency, and compromise your boiler systems reliability. Boiler scale is a deposit that forms directly on heat transfer surfaces when constituent solubility limits are exceeded and the resulting compounds precipitate onto the tube surfaces.

These mineral scales, along with sludge and process contaminants such as oils, can also cause an insulating effect which leads to overheating. The principal cause of mineral scale formation in boilers is the fact that scale-forming salt solubility decreases with increasing temperature.

difference between scale and sludge formation in boilers

Sludge and scale: Sludge is a soft, e and slimy precipitate formed within the boiler and scale is hard adhering deposit which sticks firmly to the inner surfaces of the boiler. Disadvantages of scale and sludge: Scale and sludge have disadvantages like wastage of fuel, decrease in efficiency, lowering of boiler safety, Fig.1.

Improving Boiler Life and Reducing Cast Iron Boiler Accidents

Cracks from overheating can prevent proper operation of a boiler. Excessive make-up using hard water (high mineral content) is a typical factor in scale and sludge build-up. Softening the water will reduce the mineral content, but can lead to corrosion. Test raw water to determine if water treatment is required.

Boiler water treatment - Lenntech

There are two general approaches to conditioning sludge inside a boiler: by coagulation or dispersion. When the total amount of sludge is high (as the result of high feed-water hardness) it is better to coagulate the sludge to form large flocculent particles. This can be removed by blow-down.

Along with the dissolved solids, there are some suspended solids in the boiler feed water. These suspended solids get precipitated as sludge. Sludge is normally soft in nature compared to scales, but many times sludge gets hardened because of heating inside the boiler.
