2. Boiler feedwater - Wikipedia

   en.wikipedia.org/wiki/Boiler_feedwater

   Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.

3. Boiler feedwater pump - Wikipedia

   en.wikipedia.org/wiki/Boiler_feedwater_pump

   A means had to be provided, of course, to put the initial charge of water into the boiler (before steam power was available to operate the steam-powered feedwater pump). The pump was often a positive displacement pump that had steam valves and cylinders at one end and feedwater cylinders at the other end; no crankshaft was required.

4. Boiler water - Wikipedia

   en.wikipedia.org/wiki/Boiler_water

   Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam. The term may also be applied to raw water intended for use in boilers, treated boiler feedwater , steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.

   A generic term for water-tube boilers of the Yarrow pattern. In Royal Navy practice, a reference to the specific Admiralty example of this. [4] [5] Throatplate a plate forming the lower front of the outer firebox of a locomotive boiler, below the barrel. Top-feed in locomotive boilers, a feed water check valve placed on the top of the boiler ...

6. Injector - Wikipedia

   The condensate mixture then enters a divergent "delivery cone" which slows the jet, converting kinetic energy back into static pressure energy above the pressure of the boiler enabling its feed through a non-return valve. [8] [9] Most of the heat energy in the condensed steam is returned to the boiler, increasing the thermal efficiency of the ...

7. Boiler design - Wikipedia

   en.wikipedia.org/wiki/Boiler_design

   Feed check valve - regulates the flow of water into the boiler and prevents the back flow of water in case of failure of the feed pump. Steam stop valve - regulates the flow of steam that is produced in the boiler to the steam pipe, and may also be used to stop the supply of steam from the boiler
