Boiler feedwater is the water which is supplied to a boiler. 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.. The feedtank is the major meeting place for cold make-up water and condensate return. It is best if both of these, together with flash steam from the blowdown system, flow through sparge pipes installed well below the water surface in the feedwater tank. The sparge pipes must be made from stainless steel and be adequately supported.
Boiler feedwater systems that optimize condensate return, regulate feedwater levels, and improve boiler efficiency for industrial and commercial steam systems.. A feed water tank is defined as a storage tank that acts as an equilibrium vessel for receiving water from upstream equipment and supplying water to downstream equipment in a plant. It is equipped with level switches or transmitters to control the operation of associated pumps and prevent issues such as overflow or running dry.
