suijitupian135.jpg" />I have a Weil Mclain gas steam boiler (~1992-1993). After I purchased the house the automatic water feeder never worked. (automatic feeding function, manual push-button feed works fine). In the past I normally manual fed once every two weeks. But starting from last winter I had to put water more and more frequently. Now I almost have to put water every 24 hours.

suijitupian166.jpg" />The MegaSteam oil-fired steam boiler was designed specifically for residential use and achieves 86% AFUE efficiency with a 3-pass cast iron heat exchanger - the only one of its kind in the world. Its unique design makes it highly corrosion resistant, a fact that U.S. Boiler Company backs up by giving the MegaSteam the best warranty in its class.
suijitupian193.jpg" />It performs similar function to a boiler feed unit except it feeds a deaerator instead of a boiler. A surge tank is typically used on systems having more than 20% hot condensate returns. Two designs are available—either a two-compartment style (deaerator models with "2C") or a two-tank style (deaerator models with "2T").

suijitupian51.jpg" />Large Duplex Steam Boiler Feed Pump. This is an item from my collection. Made by a well known model engineer, this is an excellent example of a "Southworth Engines" Large Duplex (Twin Cylinder) Steam Pump. The pump is double acting & will move a good volume of water and is therefore suitable for feeding a large boiler.
suijitupian17.jpg" />In order to counteract the effects of contamination, boiler feed water is treated chemically, to control (1) scale formation in the water sides of boilers, (2) corrosion, and (3) foaming and priming, and it is treated mechanically and by heating to reduce the dissolved oxygen present in the water.
suijitupian197.jpg" />'Boiler feed water pump' pumps the water at high pressure into the boiler from the 'feed water tank'. The pump is akin to the heart in the human body. Pre-Heating 'Feed water heaters', using extracted steam from the turbine, adds a part of the sensible heat even before the water enters the boiler.

suijitupian88.jpg" />Boiler feed water pressure regulators are designed for use in commercial and residential hydronic heating systems to fill the boiler and piping system with water and maintain continuous pressure. Certain valve types also provide make-up water to the system and prevent backflow when supply pressure falls below system pressure.
suijitupian195.jpg" />A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler.The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.

suijitupian158.jpg" />Boiler Operation and Maintenance. Proper operation and maintenance of your boiler and its distribution system can save significantly on energy bills. Since many boiler systems operate at an average efficiency of only 65 to 75%, the remainder of your heating fuel bill is going up the chimney or down the drain.
