Inverted Bucket Traps

Steam used for secondary heating like Coils, vessels, heat exchangers etc, generate a lot of condensate post heat transfer. This large quantity condensate can handle by the Inverted Bucket Trap. This condensate has a substantial heat component with cost tagged to it. Also this is treated and pure water and can be used as Feed water for the Boiler, saving the cost of heating, Water Bill and Treatment chemicals.

Therefore it makes sense to recycle / reuse this condensate. This function is also done by the Inverted Bucket Steam Trap, which works on the principle of Buoyancy, [densities difference of Water and Steam].The rising in condensate level fills and envelopes the Bucket causing it to sink which open the mechanically linked valve and discharges the condensate, and reverse,   when the level of condensate drops Steam enters the bucket, causes the flotation of the Bucket which close the valve and stops condensate discharge & traps the steam.

As the name suggests, a Steam Trap is a device which allows Condensate to pass through it, while trapping live Steam. Steam Trap is used to drain out the condensate in steam network, formed due to heat loss or heat transfer, without live steam loss.
A steam trap does the following multiple work:
1) It Allows venting of air or non-condensable gases present in steam network(especially during start-up)
2) It Traps live steam
3) It Discharges the condensate(formed due to condensation)
It is required at one or numerous locations to,
1) Avoid water hammer in steam pipes and other equipments
2) Improve the heat transfer capabilities of equipments
3) Avoid excessive corrosion and pitting
There are 3(three) types of steam traps
1) Thermodynamic(disc) type:
Operating principle :- It works of Bernoulli’s principle (Kinetic energy/velocity)
2) Thermostatic(bellow) type
Operating principle :- It works of thermal(temperature) principle
3) Mechanical(Float and bucket) type
Operating principle :- It works of Buoyancy principle
FOS or Safety factor is related to the discharge capacity of steam trap. Every steam trap is designed to meet a predefined discharge capacity at corresponding differential pressure. But if actual rate of condensation is higher at some plant locations due to conditions of start-up or similar conditions, we must consider FOS or safety factor to meet these extra demands of condensate discharging.
Insulation of steam traps is not recommended with few exceptions However, it depends on the operating principle of steam trap. Please note, insulation means Thermal insulation
1) Thermodynamic Type : Insulating should be limited to Ice & Rain fall from top cover side only
2) Thermostatic Type : Not recommended at all
3) Mechanical Type : Float & Bucket type are mechanical traps. Not recommended for this type too
