Boiler water treatment - Lennte

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

Furnaces: principles of design and use - ScienceDire

This chapter discusses the principles of design and use of furnaces. Almost all manufactured articles go through a process of heating at some stage. The equipment used for heating can be broadly termed a furnace. Because of the diversity of manufacturing processes and raw materials used, the types of furnace required are numerous.

Effect of fine ash particles on formation mechanism o

A part of fine ash particles tend to deposit on the heating surface and plenty of the relatively larger particles are flowing downward with flue gas. Thus, a part of acid condensation in fly ash particles is flowing away with flue gas and the other part around fine ash particles is sticking to the heating surface.

Technology Fundamentals: Solar thermal water heati

China is by far the world's largest manufacturer and user of solar water heating. By the end of 2002, the total installed area of solar domestic hot water systems there was about 40 million m²; annual production and sales volume reached about 8 million m² in 2002.

Energy management and water heating syste

2014-5-14 · The Scotch marine boiler can be identified by a central fluid backed combustion chamber, which is surrounded by fire tubes with two or more hot gas paths, passing through the heating surface area. These are not a condensing type and are limited in overall efficiency, mostly due to burner turndown capabilities and heat exchanger material.

Steam or Hot Water? SX-2 Heating Coi

2014-4-15 · boiler is eliminated by the use of hot water heat. Under these conditions, a leak will flood the tank and not damage the boiler. Heat exchangers using steam as the heating medium requireless heat transfer area, than water heated exchangers. Less surface area translates into smaller heat exchangers. These are mostly less expansive.

Fouling - Wikiped

2019-10-28 · Fouling is the accumulation of unwanted material on solid surfaces to the detriment of function. The fouling materials can consist of either living organisms (biofouling) or a non-living substance (inorganic and/or organic). Fouling is usually distinguished from other surface-growth phenomena, in that it occurs on a surface of a component

Heat Distribution Systems | Department of Ener

Steam heating is one of the oldest heating technologies, but the process of boiling and condensing water is inherently less efficient than more modern systems, plus it typically suffers from significant lag times between the boiler turning on and the heat arriving in the radiators.
