ASME PTC 30 PDF

Description

PTC 30 provides uniform methods & procedures for testing the thermodynamic & fluid mechanical performance of air-cooled heat exchangers(ACHE).
Code provides uniform methods procedures testing thermodynamic fluid mechanical performance air cooled heat exchangers, calculating adjustments test results design conditions comparison guarantee. scope covers, not limited to, draft forced induced types, natural fan assisted exchangers. transfer surface standpoint, covers tube bundle orientations, including: vertical, horizontal, slanted conduit bare surfaces finned included type exchanger components. conventional round tubes circular fins assumed code, can modified mutual agreement apply configurations. cooling restricted atmospheric air, tube-side chemical element, compound mixture, single phase flow, liquid gas, two flow. written assumption (ache) may tested discrete process stream only one investigated. cases, modifications must made presented. shall agreed parties test. also includes, directly reference, recommended obtaining data, measurements, observations, samples determine following: (a) physical dimensions (b) flow rate (c) air-side pressure differential (d) driver power (e) sound level (f) (g) environmental effects (h) wind velocity (i) temperatures (j) entering temperature (k) exit (l) (m) pressures (n) (o) composition (p) percent capability (q) drop. ptc 30 & air-cooled exchangers(ache).
