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.
