This is a sealed metal tube which has been evacuated of air and contains a small quantity of liquid which, for boiler applications, could be water. When heat from the flue gases is applied to one end of the heat pipes the water in the tube boils, turning to steam and absorbing the latent heat of evaporation.
These extended surfaces can range from flat fin tube in line with the gas path and parallel to the tube, rectangular or "H" fin that is perpendicular to the tube or a spiral wound helical fin. In power boilers, bare tube economisers are also common as fouling from entrained gas particles could cause blockages in a finned economiser.

Boiler Economizer is usually fitted to increase the efficiency of the boiler by increasing the heat recovery surface so that the maximum amount of heat is recovered from the burnt gases. This is achieved by heating the feed water to the boiler from the burnt gas before it leaves the furnace. In this article we discus the inspection carried out in the economizer and on it gas side of the boiler.
2019-12-5 · There are different components present in feed water and steam circuit of boiler and we should know some essential components of these circuit and these are Economizer, boiler drums, water tubes, and super heater. EconomizerEconomizer is a heat exchanger which takes heat from the flue gas, and increases the temperature
2019-1-30 · Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.
2019-12-5 · Boiler or more specifically steam boiler is an essential part of thermal power plant. Definition of BoilerSteam boiler or simply a boiler is basically a closed vessel into which water is heated until the water is converted into steam at required pressure. This is most basic definition of boiler. Working
2014-4-28 · In water tube boilers roof and floor tubes are sloped at 15' to ensure circulation The U-tube heating elements are passed through the manhole dorr and expanded into headers welded into the dished end of the drum. This is located in the primary drum and is supplied from the exhaust economiser to keep both circuits warm thereby preventing
2019-9-28 · A watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up
