Boiler maintenance and operation will maintain reliability and help increase the life of the boiler, as well as improving energy and efficiency. Here are some steam boiler
maintenance checklists and tips.
One of the main reasons is that the boiler is overheating. This may be due to several key factors
low water conditions
scale
corrosion
These are some of the main causes of steam boiler losses. But there are ways we can prevent these factors
low water conditions
This is one of the leading causes of accidents, so anytime you have a low water accident. But a few things happened.
First, there is a problem with the water supply. This may be due to the feed water pump or feed water controller. So this may be the source of the problem. But we have
a safety device on the boiler, low water supply cut off or burner designed to cut off the boiler before the water level gauge reaches the low designated area.
If the water level drops and the water level also drops below the surface of the tube, then the flame will now pass through the tube. It overheats the metal of the tubes
and when the water level is low we get things like a melting bathtub and bad things happen to the boiler.
Build scale
Scale is caused by impurities carried in the feed water. When a steam schedule is running, significant steam losses may occur in the system.
Make up for that lost steam. If the chemical composition of the water does not completely coat the boiler, these impurities will be deposited on the internal surfaces of
the boiler in the form of scale.
Reduce heat transfer from fireside facilities to boiler water side surfaces. This affects the reliability of the steam boiler, the life expectancy of the boiler and the energy
efficiency of the boiler, so if we can correct the water chemistry in the steam boiler then we can make a big improvement. Another key factor in maintaining water
chemistry is treating the incoming feed water. You can treat your water by installing a water softener, which will prevent scale from forming in your boiler.
corrosion
Corrosion is another factor that causes steam loss in boilers, and you can see orange bubble traces when you remove bubbles submerged in pipes.
When they flood into the pipes, they can cause leaks from the water side surface of the boiler to the fire side surface of the boiler. If the leak is severe we will see corrosion
in the pipes and the only way to correct and eliminate this problem is.
