13. Flash boiler
A flash boiler is a type of water-tube boiler, whose tubes are strong and close together with water pumped through the tubes. The tubes are kept very hot so the water feed is quickly flashed into steamand superheated.
Water tube boiler; Fire tube boiler; The design and arrangement of both the types is just the opposite. In water tube boilers, the feed water passes through the tubes and the hot gases are made to pass over them, while in fire tube boilers, the hot gases passes through the tubes and the feed water surrounds them.

Water-tube boiler Definition: A closed vessel in which water flowing inside the tubes and hot flue gas pass outside the tube is called a water tube boiler.
The importance of the boiler feedtank, where boiler feedwater and make-up water are stored and into which condensate is returned, is often underestimated. Most items of plant in the boiler house are duplicated, but it is rare to have two feedtanks and this crucial item is often the last to be considered in the design process.
Waterside tube corrosion is generally caused by the existence of contaminants in the boiler feedwater, which is a combination of makeup water and condensate returns. Feedwater contaminants include oxygen, excessive water treatment chemicals, oils, miscellaneous metals and chemical compounds, and resin.
Boiler scale is the hardened sediment from boiler feed water deposited by conducted heat inside the tubes in a water tube boiler and on the outside of tubes in a fire tube boiler. Too high a density of the boiling water is the cause and can only b

A combination boiler, or combi boiler as it is typically known, is a boiler which provides the heat for both the radiators and the hot water outlets in the home. Around 70% of British homes use a combi boiler, making them the most common boiler type in the UK. The key aspect of combi boilers is that there is no need for water cisterns in the loft or a hot water cylinder.
Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%.
The conventional boiler water test finds only the presence of OH and half of CO3. Standard value of P alkalinity in Boiler Water is between 50-300mg CaCO3/l. Effects. Higher value of P alkalinity leads to scale formation and overheating of the inside of the boiler causing internal damage. 6. Chloride ion. It causes generation of scale formation.
Water Treatment. Make sure your boiler is working at peak efficiency with properly treated water. Our water softeners, dealkalizers, filtration systems, chemical feed systems, blowdown separators, and sample coolers work together to increase the life of your boiler.
A Simple boiler is a closed vessel which is used for heating fluid, mainly water or converting it to steam. Steam thus produced can be used as a heating medium or as a working fluid in a prime mover, where it turns thermal energy to mechanical energy, which in turn may be converted to Electrical Energy.

Water does not run uphill! If boiler and boiler feed unit are on the same floor, enter a value of "0" for feet of head. If boiler is located on a floor above the boiler feed unit, enter vertical height (in feet) from the pump discharge of the boiler feed pump up to the inlet piping on the boiler.
Why a RO System is necessary for Boiler Feed Water Pretreatment: Having a reverse osmosis system as boiler feed water pretreatment can: - Reduce fuel costs through lower heat loss and increased boiler cycles. Reducing the total dissolved solids (TDS) in the RO product water can increase the boiler's cycles of concentration.
In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler. These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed tubes and membrane Wall.
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.
The only thing that allows a boiler to withstand these furnace temperatures is the presence of water in all tubes of the furnace at all times that a fire is present. Low-water conditions will literally melt steel boiler tubes with the result closely resembling a spent birthday candle, as shown above.
The ASME Boiler and Pressure Vessel Code (ASME BPVC), which is administered by ASME (New York, N.Y.; www.asme.org; founded as the American Society of Mechanical Engineers), is a well-established standard for the design and fabrication of boilers and pressure vessels.ASME code-symbol stamps show compliance with the requirements of the standard, but code stamping of steam systems in ethylene and

In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
A combination boiler, on the other hand, doesn't need any tanks to heat your water. You see, any time a hot water tap is turned on in your home, cold water from your home's main water line runs through the boiler, is quickly heated by coils filled with hot water, then rushes directly to the faucet calling for hot water.
