• Perform preliminary calculations and suggest design modifications.


• Analyze plant draft system or inlet/discharge systems of rotating equipment like fans/gas turbines backed up by CFD based air flow dynamic modeling.


• Develop solution and propose design improvements.


• Design, engineering, manufacture and installation of optimized solutions.


• Performance evaluation/measurements before & after modifications.

Assignments Executed based on technology provided by APT FLOW TECHNOLOGIES INC in INDIA

• Improvement of performance (Energy Efficiency) of ID & FD Fans of 210 MW Bandel Coal fired Power Plant of West Bengal Power Development Corporation (WBPDCL) by modification of discharge ducts of ID & FD fans. The technology offered cumulative energy savings of about 350 KW from 2 FD and 2 ID fans which corresponded to 3.75" WC pressure drop savings (2" WC savings in FD fan discharge system and 1.75" WC savings in ID fan discharge) over the existing system.
