Is the inverted bucket type steam trap connected directly? ?
Thread Content
Help: This system uses steam to heat ethylene glycol for heating the workshop. 1. The steam comes from the plant at 2.2 MPa; it is directly depressurized to 0.45 MPa (without humidification), resulting in supersaturated steam ； 2. The heat exchanger used is a coiled type, with a capacity of 12㎡ per unit ； Three in parallel ； 3. Steam enters at DN100 and 0.45 MPa from the shell side, while condensate is discharged from the shell side at DN40. The three heat exchangers are combined, and a DN40 PN16 inverted bucket type water transfer device is used ； During use, normal drainage occurred at first, but later it started to drain directly, with steam flowing straight from the trap into the condensate tank. Is there a problem with the selection? The originally designed saturated steam at 0.4 MPa resulted in a condensate discharge volume of 900 kg/h.
Why has it lost popularity? Please, dear uncles, help solve this :)
What comes out must be steam, not flash vapor, right?
Personal understanding: It is advisable for each group of heat exchangers to have its own drainage system.
