SCRUTINY OF TECHNICAL PROPOSAL OF NEW BOILER

Minor changes in words, which are added purposefully, shall change the whole scenario in the project execution stage, when things go wrong. Later both SELLER & PURCHASER tries to save money on behalf of the terms in SIGNED CONTRACT

Awakened & Technically Strong PURCHASER saves Time-Money-Energy-Resources while others just trying to wash-off foot-prints left behind due to negligence

I have seen most of the PURCHASERS believing in CONSULTANT to help them. Definitely they help PURCHASER by highlighting a highly negligible issues and points of erection fault and physically verified points like welding, alignment, aesthetics during project execution

Self experienced in my Professional Career that Critical Issues and Design Failures NEVER highlighted / disclosed by CONSULTANT, purposefully. Just to maintain business relationship with Seller

Seller act on Common Market Principles:

“IF PURCHASER knows the things, we know. If nobody knows the things, we do not know”

“Do not try to Educate Purchaser, Otherwise Project will never close”

“One year Contractual Guarantee tenure will pass in communication and operational team fault”

SCRUTINY OF TECHNICAL PROPOSAL FOR CFBC BOILER - UNDER EXECUTION

Read the Detailed Comparison on Technical Proposal of CFBC Boiler given to Purchaser by Seller in attached documents

COMMON STATEMENT ON DISTURBANCES & FAILURE:

“It was a Design Prediction based on General Engineering Practices”

“Technical details may change during Detail Engineering. Normally, After Award of Contract, Value engineering start for changes based on contractual language”

For example:

  1. Deaerator Outlet Feed water temperature 130 degC , Economizer Inlet Feed water Temperature 130 degC, Boiler Feed Pump Design Temp. 130 degC Is it Possible as Good Engineering Practice? No temperature drop from Deaerator Outlet to Economiser Inlet. BFP design & operating water temperature is same
  2. Peak load 110% trial for ½ Hour in every 08 hours Boiler Auxiliaries always design on 100% MCR while Boiler Guarantees for 110% peak MCR trial run. Ensure safety design margin over and above 110%
  3. Air Pre Heater (APH) bypass arrangement. No value given for %age of Air flow Bypass Keep minimum 50% total air flow in bypass
  4. Spray Water Quantity for steam temperature control range of 60-100% MCR OR 50 -100% MCR Limit to less than 3% of MCR Flow. Take Curve for spray water flow range
  5. Radiation loss will be as per Old outdated PTC 4.1 / ABMA chart. It will spoil the insulation and cladding application and design quality
