VKG Energia OÜ — Burner design (20 MW) and boiler modification for low-calorific generator gas (3.6 MJ/nm³)

Burner design (20 MW) and boiler modification for low-calorific generator gas (3.6 MJ/nm³).

Project Overview

Engineering design and reconstruction of the BKZ-75-39FSl power boiler for stable combustion of low-calorific generator gas (LHV ~3.6 MJ/nm³). Custom 20 MW gas burners were engineered with specialized mixing aerodynamics to guarantee flame stability and complete burnout without support fuel co-firing.
