Repair or replace the steam traps. There's a water leg before the condensate- or boiler-feed pump receiver. In two-pipe systems, you have steam traps on the radiators instead of air vents. The steam pushes the air through the traps, into the dry returns and toward the condensate- or boiler-feed pump's receiver.
Generally one trap failing will only affect the equipment it is on. If it is on a steam header, then the water it is supposed to remove will be transferred on down the line to the next trap or piece of equipment. If the trap is stuck open, you will have excessively hot water in the condensate tank and possibly even some pressure.
Boiler design is the process of designing boilers used for various purposes. The mainfunction of a boiler is to heat water stop the supply of steam from the boiler; Basic boiler mountings and their function List of boiler acting also s vents. Water tubeboilers with high evaporation through and raising steam in the boiler.
Due to this increased pressure, feed water is forced into the boiler through feed check valve. Figure: Steam injector . Application . They are commonly used in vertical and locomotive boilers. Steam trap . Function . In any steam system, water may be formed due to partial condensation of steam in the piping system.
As hot steam travels from your boiler to the point of use, some cooling is inevitable. The result is condensate and gases. The job of the steam trap is to isolate and remove these impurities from the live steam. Steam traps that function properly help maintain purity and efficiency throughout the system. The best way to test steam trap function is to listen to them with an ultrasound solution.
steam trap - Self contained valve which automatically drains the condensate from a steam containing enclosure while remaining tight to live steam, or if necessary, allowing steam to flow at a controlled or adjusted rate. Most steam traps will also pass non-condensable gases while remaining tight to live steam.

Working Principle of Boiler
To do this most steam systems have multiple steam traps plumbed in throughout the piping system. These steam traps were installed to remove the liquid condensate and air from the pipe so that pipe stays filled with “dry” steam. As the trap allows the dry steam to pass, it redirects the hot liquid condensate to a condensate receiver where it can be reused in the boiler.
A steam trap is an automated device designed to remove condensate from a steam-containing enclosure while retaining live steam at the same time, giving the live steam more surface to maximize heat transfer efficiency. By removing condensate, steam traps allow it to be collected and re-used.
Steam Trap Function Steam traps are automatic valves used in every steam system to remove conden-sate, air, and other non-condensable gases while preventing or minimizing the passing of steam. If condensate is allowed to collect, it reduces the flow capacity of steam lines and the thermal capacity of heat transfer equipment. In
Since condensate has already been through the steam system, it will take far less heat (and fuel) to turn it back into steam than it would to make steam of an equal quantity of cold water. That is why a growing number of steam users return the condensate back to the boiler where the whole process starts over.
The steam-generating facility, located in the boiler room, consists of boilers, feedwater systems, heat exchangers (e.g., economizers), boiler and system controls, fuel and gas handling equipment (e.g., fuel trains, stacks), and steam/water

Steam comes off the top of the Steam Main, comes down to the trap along the vertical pipe in the left of the photo, as it is cooled by heat loss from the pipe. This steam trap is therefore acting mostly as a “steam cooler” wasting steam from the Steam Main.
A: A Steam Trap performs two functions. First, it is an air vent. As steam fills the pipes on startup it must displace air, and during equipment operation all air formed must be vented. Secondly, it is a water outlet valve, which allows residual water to be removed from the steam system faster than it is formed.
The authors refined a steam trap survey tool that estimates steam losses and energy savings for failed steam traps as a function of up to twelve coefficients and parameters, including: the energy lost at a trap anything but practical, and Trap pressure Orifice size Hours of operation Leak factor Boiler efficiency
In general, a steam trap consists of a valve and a device or arrangement that causes the valve to open and close as necessary to drain the condensate from piping without allowing the escape of steam. Steam traps are installed at low points in the system or machinery to be drained.
