Hot water boiler without softening water will be what harm to the boiler
1, waste of fuel
Boiler fouling, so that the heat ingressed surface heat transfer performance is poor, fuel combustion heat can not be transferred to the pot water in time, a large number of heat is taken away by smoke, resulting in smoke temperature is too high, if the loss of smoke increases, boiler thermal efficiency is reduced. In order to maintain the boiler rating parameters, it must be added fuel, so waste fuel. About 1 mm of scale waste disterated by 10% fuel.
2, damaged by heat ingress
The boiler with scale, due to poor heat transfer performance, the heat of fuel combustion can not be quickly transferred to the pot water, resulting in the temperature of the furnace and flue gas increased. Therefore, the temperature difference between the two sides of the heat ingle increases, the metal temperature increases, the strength decreases, under the pressure of the pot, drum pack, or even blasting.
3, reduce the boiler output
After boiler scaling, due to poor heat transfer performance, to achieve the rated evaporation, we need to consume more fuel, but with the thickness of the scale increase, the volume of the furnace is certain, fuel consumption is limited.
4, corrosion
4.1, metal damage: water contains oxygen, acidic and alkaline substances will produce corrosion on the metal surface of the boiler, so that its wall thickness thinning, depression, and even perforation, reducing the strength of the boiler, seriously affecting the safe operation of the boiler.
4.2, produce scale corrosion: high-priced iron scale, easy to cause contact with scale metal corrosion. And iron corrosion products and easy to re-form scale. This is a vicious circle, it will quickly lead to damage to boiler parts.
5, soda co-slinging
In addition to improper operation of soda co-growth, when the furnace water contains more sodium chloride, sodium phosphate, grease and silicate, or the organic matter and alkali action in the pot water soaping, in the boiling and evaporation process of the pot water, the liquid surface will produce foam, the formation of soda co-steam.
6, destroy the water cycle
Boiler sub-natural circulation and forced e68a847a643333361303031 ring, all kinds of boiler water circulation is a certain balance, whether it is up or down tube, must have enough cut-off area, when the furnace pipe wall corrosion scale, it directly leads to the reduction of the pipe cut-out area, water vapor resistance increases, destroys the normal water cycle of the boiler so that the temperature of the heat-resistant metal wall is increased. Water circulation stop local furnace pipe due to the increase in pipe temperature and produce local vaporization has occurred burning or burst pipe accident, directly threatening the normal operation of the boiler.
