Engineering Specifications for Flue Gas Cooler (057-E-15B)
This detailed engineering drawing presents the comprehensive design of a flue gas cooler bundle assembly with specialized manway access components for a BS-VI project at Paradip Refinery. The drawing shows multiple critical sections including longitudinal views, cross-sections, and detailed component specifications.
Bundle Assembly Details:
– Heat exchanger with inlet/outlet headers (OD 323.9×17.48mm and OD 355.6×19.1mm respectively) manufactured from A312 TP347H material
– Primary tubing consists of 350 tubes (35×10 configuration) utilizing Incoloy 800HT material
– Seamless tubes with OD 60.3mm (2″) and OD 48.3mm (2″) with 5.54mm wall thickness
– Includes fixed and sliding saddle supports made from SA516 Gr.70 material
– Incorporates solid fins (CS 13×1.3mm) at 197/m spacing
Design Parameters:
– Design temperature: 278°C
– Design pressure: 51 kg/cm² gauge/Full Vacuum
– Estimated bundle weight: 27,500 kg empty, approximately 34,600 kg with water filling
– Heat transfer area optimized for processing flue gas
– Designed to ASME Section I and IBR 1950 (with 2017 amendments) specifications
Manway Construction:
The second sheet details the manway assembly with comprehensive bill of materials including:
– SA234 Gr.WPB header cap with ID 702mm and 30mm thickness
– SA105 manway ring (40×520×430×250mm)
– Elliptical manway cover (70×528×438mm)
– Dog stays, guide plates, bolt hooks and other necessary fastening components
The drawing demonstrates meticulous attention to the heat exchange mechanism while providing essential maintenance access through the carefully engineered manway system.
