Eesti Energomontaaž AS / FORTUM — Detail Engineering for Air Duct and Heating Surface Modifications on TP-101 Boiler for Two-Stage Combustion (NOx Reduction)

Detail engineering for air duct and heating surface modifications on TP-101 boiler for two-stage combustion (NOx reduction).

Project Overview

Detailed engineering design for the modernization of the TP-101 utility boiler to implement staged combustion (Overfire Air / OFA). The scope included secondary and tertiary air duct re-routing, heating surface arrangement optimization, and insertion of overfire air ports to effectively suppress primary NOx formation in the furnace zone.
