treatment when boilers operate at low pressure, much of the condensate is returned and the raw water is of good quality. However, in moderate and high pressure boilers, external pretreatment of the make-up water is mandatory for good results. With today's higher heat transfer rates, even a small deposit can cause tube failures or wasted fuel.

Boiler feedwater - Wikipedia

Characteristics of boiler feedwater. Boiler water must be treated in order to be proficient in producing steam. Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range.

High Pressure Boilers: Features and Advantages ~ ME Mechanical

Oct 27, 2016· Intensive heating the furnace temperature in high-pressure boilers is high enough and therefore, 70% of heat is transferred to water by radiation. This is a faster way of heat transfer. Once through construction in high-pressure boiler operating at and above the critical pressure, the water directly flashes into steam in the tube itself. It eliminates the need of a boiler drum.

17.3 High pressure hot water. Whereas hot water systems will normally operate at boiler pressures between 50 kPa and 300400 kPa, high pressure hot water systems are used for industrial applications with pressures up to 20002500 kPa. The boiler construction is as for steam boilers, but the water line is held higher and the pipe system is sealed, with circulation by pumps.
