The Float & Thermostatic Steam Trap is one of the most efficient condensate removal devices used in marine steam systems. It automatically removes condensate and air from steam lines while preventing the loss of live steam, improving overall thermal efficiency and safe operation onboard ships.
The float mechanism rises and falls with the condensate level inside the trap. As condensate enters, the float lifts the lever mechanism and opens the valve disc, allowing condensate to discharge continuously. When steam reaches the trap, the thermostatic element senses the temperature increase and closes the valve to prevent steam loss.
Main components of the steam trap include the float, thermostatic element, valve seat, valve disc, strainer, lever mechanism, inlet, outlet, and body casing. Each component plays a vital role in maintaining efficient condensate drainage and protecting the steam system from water hammer, corrosion, and energy loss.
Float & thermostatic steam traps are widely used in marine boilers, fuel oil heating systems, cargo heating systems, steam tracing lines, and engine room auxiliary equipment due to their reliable continuous discharge capability.
Regular maintenance is essential to ensure proper operation. Engineers should inspect strainers for blockage, check valve seats for wear, verify float movement, and monitor for steam leakage or condensate backup during operation.
