Problems with the Old Selection Criteria for Traps: After seven years of monitoring and experimentation on Trap Performance at the Royal Bank of Chemical Industry in Huddersfield and Grangemouth (England), the first experiment at two manufacturers Based on the monitoring and experimentation of the trap performance and fresh steam loss carried out by the Chamber, Royal Chemical Industry Chemical eventually modified the selection of the trap in its Engineering Design Guidelines. After the change of the new "guidance" includes trap selection table. The old selection criteria for traps have a number of drawbacks, most notably the lack of mention of the type of hydrophobic equipment and methods of hydrophobicity. The chosen trap often does not match the actual load. In particular, thermodynamic disc traps, the foundations of the old selection criteria, were mistakenly considered as universal traps by people, especially shop floor personnel. Experiments revealed many problems with the old selection criteria of traps: 1, the steam in charge of the trap life is too short. 2, trap performance has lapsed, and the actual load selection does not match. 3, as the most widely used thermodynamic disc traps, the worst energy-saving, but also with inverted bucket traps, the life expectancy is very short. 4, bimetal traps easily unstable. Second, trap selection techniques: The new "guidance" includes the trap selection table. Traps selection skills: 1, inverted bucket traps: As the first choice for all process loads and steam main traps, that is, all the need for steam hydrophobic occasions. 2, Float thermostatic trap: for process hydrophobic, especially in the control of the load of 3.5 kg (50psig) of the application or the air content is high, the inverted bucket trap installation problems. 3, the balance pressure trap: used as an important heating or heating system. 4, bimetal thermosyphon trap: for heating pipelines or heating system low temperature or frost conditions. This type of trap allows to maximize the use of sensible heat in the condensate or to prevent overheating of the product. The valve body is all stainless steel. 5. Thermodynamic Disc Traps: As an alternative to inverted bucket traps, as long as proven by previous experience, they are used with limited liability on steam supervisors and tracing pipes under pressures up to 17 kg, or as products Replace for higher vapor pressure. Not recommended because of its low energy efficiency and short lifetime (and not allowed at Huddersfield and Grangemouth). 6, in the heat less demanding occasions, with the thermostatics steam trap to replace the thermodynamic disk will increase the energy saving effect, while ensuring the service life. 7, mechanical trap valves (inverted bucket and float trap) both in condensate load or load is small, can ensure that the steam does not contain condensed water, while the thermosyphon trap when the load increases easily accumulate Condensation water.
