Consulting - Specifying Engineer | Boilers: Types

Even though the modern boilers are termed as high pressure boilers, it does not mean them fully. Because high pressure operation is only one of the characteristics of modern boilers used for power generation. Other aspects/characteristics are as follows: (1) Modern power boilers are water tube. (2) They use forced type of water circulation.

Metal cations found in boiler water, such as calcium, magnesium, iron, and copper, can be solubilized to prevent deposition and scale formation. The functional agents in this type of treatment are known as chelants. Chelants are organic, anionic chemicals that form soluble compounds with the metals.

Boiler Introduction | CleanBoiler.org

Sep 26, 2016 · For industrial companies using a boiler for its facility, some type of boiler feed water treatment system is usually necessary to ensure an efficient process and quality steam generation. The most appropriate boiler feed water treatment system will help the facility avoid costly plant downtime, expensive maintenance fees, and boiler failure as a result of scaling, corrosion, and fouling of the

High Pressure Boilers: Meaning, Types, Characteristics

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 …

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

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

What are the important characteristics of a water supply

Example: If water heater A uses 1 therm to produce 100 gallons of hot water heated up from 40 degF to 120 degF, and water heater B uses 2 therms to produce the same 100 gallons of hot water heated up from 40 degF to 120 degF, then water heater A will cost half as much to operate as water heater B. In other words, the fewer therms/gallon or

Characteristics of Two-phase Fluid Flow. All two-phase flow problems have features which are characteristically different from those found in single-phase problems. In the case of steam and liquid water the density of the two phases differs by a factor of about 1000. Therefore the influence of gravitational body force on multiphase flows is of
