how scale and sludge are produced in a steam boiler

On the other hand, if the precipitated matter forms a hard, adhering crust/coating on the inner walls of the boiler, it is called scale. Sludge is a soft, loose and slimy precipitate formed within the comparatively colder portions of the boiler and collects in areas of the system, where the flow rate is slow or at bends.

What Is Boiler Sludge? | How to Clean a Steam Boiler …

14/8/2019 · Boiler sludge can hinder your system's efficiency in a few ways. First, when sludge builds up within the tank, it can negatively affect your boiler's heating performance. Boilers with a lot of sludge have to work harder to heat up and use more energy as a result – which leads to higher bills for you.

Dan Holohan: Sludge, scale and bouncing boilers | 2021 …

5/5/2021 · Scale can cause lots of problems in steam boilers, especially if it's a process-steam boiler and some or all of the condensate gets dumped (think bakeries). Lost condensate means lots of fresh, cold feed water, and that brings in the calcium and magnesium, which will cling to the hottest surfaces of the boiler, slow heat transfer, raise fuel bills and cut

Introduction to boiler scales - Leaders in Steam …

If the pH of the boiler water is higher than 11.5 and at the same time the boiler water is transparent, this fundamentally indicates the absence of sludge formation processes in the boiler. At the same time, if the pH of the boiler water is from 8.5 to 9.5 and the water is transparent in most cases this indicates an active scale formation in the boiler, and requires emergency measures.

Foaming and priming in boilers - Lenntech

Causes, and prevention of foaming and priming in boilers, prevention Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water.
