Why is my boiler drum inclined?
This is to encourage convection in the tubes, as heat rises. A circulation between the water drum and steam drum is set up in order to heat the water uniformly; the heated water wall is called the riser, the return (cooler) water wall is the Downcomer. It also saves space compared to a horizontal firetube boiler.
What should boiler water conductivity be?
6,000 µS/cm
If you want to prevent corrosion in your boiler, the water should have a conductivity reading that’s below 3,000 PPM, which equates to 6,000 µS/cm.
How do I know if my boiler has sludge?
Yes, you can check for boiler sludge, and the good news is that it’s fairly easy to do. Simply release the air out of one of the radiators and observe the color of the water that drains out of it. If the water is clear, your system is free of sludge.
What causes boiler sludge?
Sludge is a water-formed deposit which can include all solids carried by water. It reduces heat efficiency levels and can create scale formation in boilers. How Does Sludge Form? Sludge build-up forms when suspended materials found in the water stick onto the inner surfaces of hot boiler tubes.
What is a steam drum in a boiler?
A steam drum is a standard feature of a water-tube boiler. It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.
Why are tubes in a water tube boiler inclined?
As the water becomes lighter, it passes up through these inclined horizontal tubes and ultimately comes back to the boiler drum through riser. During travelling of water through inclined water tubes, it absorbs heat of the hot gases, surrounds the water tube, consequently steam bubbles are created in these tubes.
What the inspector looks for when inspecting a boiler?
Internal Boiler Inspection Items All internal walls and surfaces are inspected, looking for any signs of leaks, corrosion, overheating, or other structural issues within the boiler. Waterside areas. All waterside areas of the boiler are inspected, including blow-off, water connections, and steam areas.
What does a boiler inspection consist of?
An internal boiler inspection consists of all waterside areas of the vessel (steam, blow-off, and water connections), and fireside conditions, as well as dearators, superheaters, and economizers.
What is a good conductivity level in water?
Mid range conductivity (200 to 1000 µS/cm) is the normal background for most major rivers. Conductivity outside this range could indicate that the water is not suitable for certain species of fish or bugs. High conductivity (1000 to 10,000 µS/cm) is an indicator of saline conditions.
Is high water conductivity bad?
Salinity and conductivity measure the water’s ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. Pure, distilled water is a poor conductor of electricity.
