As a result, the sludge and scale formation in boiler is prevented. Moreover, this treatment : (1) prevents the deposition of iron oxides in the boiler, (2) reduces the carryover of oxides with steam, and (3) protects the boiler units from corrosion by wet steam (steam containing liquid water). 11.5 CAUSTIC EMBRITTLEMENTGet Price
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Get Price
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.Get Price
Generally, the typical thermal efficiency of incineration boilers is as follows: for a waste heat boiler it is 63%, while that of the steam turbine generator combined system is only 30%. Therefore, when the effective thermal value of the solid waste is not high, it is usually used in the waste heat boiler to produce steam or recycle hot water.Get Price

Dec 03, 2019 · Boiler water treatment is the conditioning and treatment of boiler feed water with the purpose of meeting three objectives. In order for boiler water treatment to be maintained, there must be a continuous heat exchange, protection for high-quality steam, and corrosion protection. Boilers are designed to heat fluid, after which the vaporized or heated fluid will exit …Get Price

- Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70 degrees C (158 degrees F), and Legionella cannot survive at that temperature. - Atomizing humidifiers use mechanical devices or pneumatic air to create a water mist that evaporates into the air stream.Get Price
