In contrast to standard practice in Greece, the boiler is installed on the roof of a multistory industrial building in downtown Piraeus, so removal of the boiler intact is very expensive. The existing old steam boiler at G. Keranis Tobacco S.A., Piraeus is a special type of water tube boiler with vertical tubes (Rheinstahl - Henschel IK 5-12 IS).

Scaling in boilers - Lenntech

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the

How to Destroy a Boiler -- Part 2

The undetected contamination of condensate returns is another common problem that leads to boiler feedwater contamination. Contaminants can vary from metals such as copper and iron to oils and process chemicals. Heavy metal contamination is usually a function of the construction materials of the process equipment and the condensate system.

Your choice of paint will also depend on what kind of heating system you have. Those of us with forced hot water systems don't have to worry about using heat resistant paint, since these systems don't get very hot - water usually leaves the boiler at 180 ºF (80 ºC), but by the time it reaches the radiator, the temperature will have dropped up to 50 ºF (20 ºC), and the radiator covers

Boiler - Wikipedia

Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

Boilers Explained: What are the Different Types of Boilers

This means the boiler doesn't need to work so hard or use as much fuel to heat your home or hot water, saving you money on your fuel bills and reducing carbon emissions. Because it doesn't get so hot, the flue of a condensing boiler is usually made of plastic, rather than metal, like the flues of non-condensing boilers.

The economizer is made up of a bunch of horizontal water tubes usually located in the back pass or second pass (after the primary superheaters and reheaters) of the boiler through which the feedwater enters the boiler to absorb residual heat from the exhaust flue gas and transfer it to the steam production cycle. This process, on one hand
