Selection of Plate-Structured Condensation Water Tanks

Selection of Plate-Structured Condensation Water Tanks

I. Calculate Core Parameters First

Heat load: Calculated based on medium flow rate, temperature and latent heat; reserve a 10–20% margin for heat exchange area.

Temperature/Pressure: Confirm the temperature, pressure and allowable pressure drop (≤50–100 kPa) of condensation medium and cooling medium.

Medium characteristics: Check if the medium is corrosive, contains particles or is prone to scaling.

II. Select Plate and Structure Type

Corrugation: Herringbone (high heat exchange efficiency, first choice for pyrolysis furnaces); wide-channel (anti-clogging, for particle-containing medium).

Flow channel: Narrow channel (high efficiency); wide channel (anti-clogging).

Structure: Removable type (easy to clean); fully welded type (zero leakage, high pressure resistance).

III. Select Materials (By Working Condition)

Conventional oil gas/steam: 304/316 stainless steel

Strong corrosion: Titanium, Hastelloy

Low temperature/cleanliness: 316L, pure copper

IV. Match Working Conditions and Economy

Pyrolysis/refining: Herringbone corrugation, 316 stainless steel, removable/fully welded type

Particle-containing/scaling-prone medium: Wide flow channel, large spacing

High pressure/high temperature: Fully welded type, high-temperature alloy

Priority principle: Heat exchange efficiency ＞ Anti-clogging ＞ Cost
