Salt Formation In Boilers For Steam Production

Water softener use for a steam boiler - good idea

The formation of salts of silicic acid in the boiler is possible in the presence of feed water hardness salts and high coefficient of evaporation of boiler water. In this case, if there is hydrate in the boiler water, it will not form a solid scale of magnesium silicate, but crumbly talc.

What happens to a boiler when the drum safety lifts? - Quora

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

Dec 21, 2017 · In water tube boilers, the water to be heated flows in the tubes and the combustion gases flows around the tubes, thus converting the water into steam. These types of boilers are used where high steam and pressure are required. The capacity of these boilers varies from 4500 to 1,20,000 kg/h [3, 4].

On the issue of sludge and scale formation in a steam boiler

Dec 18, 2011 · Salt, along with the boiler action of water and the very high temperatures of the cast iron above the water line would be a an excellent way to destroy a cast iron boiler. The only other method that I could think of that would be more effective in destroying a boiler would be dry firing it until its cherry red, then suddenly filling it with water.

How is NOx Formed. In industrial boilers, NOx is primarily formed in two ways: Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils. The rate of NOx formation generally
