Verwijderen condensaat Levensduur & betrouwbaarheid Ontluchten Minimaal stoom verlies CO2 evacueren Corrosie Bestendig Ongevoelig zijn voor vuil Ongevoelig zijn voor tegendruk What are the roles of the steam trap? What are the characteristics that your expect from the steam trap? The main role of a steam trap is to remove condensate, air and CO2 from the steam system as quickly as they accumulate. Steam traps are key components in any steam system and, to be effective, must provide the following: Minimal steam loss Long life and dependable service Corrosion resistance Air venting CO2 venting Operation against back pressure Freedom from dirt problems

4 Nadeel slecht evacueren van CO2:
Er ontstaat corrosie in de leiding ( CO2 + H2O H2CO3 ) Onderkoeld condensaat + CO2 = Koolzuur

36 Dimensioneren van afwateringspunten
Aanbevolen afwateringslengte per stoomcollector The length of the drip leg is determined by the type of warm-up the system is designed to experience. If system startups will be supervised, the drip leg length should be at least 1-1/2 times the diameter of the main, but never less than 250 mm. If system startups are not supervised(automatic warm-up), make drip legs a minimum of 710 mm in length.

46 Andere aanbevelingen voor piping Design
Plaats voorzien voor isolatie & steunen Plaats voorzien voor wandelpaden, ladders of werkplaatsen Exentrische overgangstukken voorzien Other best practices to follow include: All piping must have sufficient clearance for insulation and supports. All piping must allow for a clearance of 7 ft (2 m) on walkways, stairways, work areas, etc., unless otherwise specified in the project and approved by the process manager and the plant. All horizontal pipe runs with a size reduction must use eccentric reducers at the reduction and to be flat on the bottom (FOB).
