VKG Energia OÜ — Experimental Limestone Injection Test Rig on BKZ-75-39F Boiler for SO2 Binding Research

Experimental limestone injection test rig on BKZ-75-39F boiler for SO2 binding research.

Project Overview

Design, fabrication, and installation of a pilot-scale experimental test rig dedicated to investigating in-furnace SO2 desulfurization during pulverized oil shale combustion. The system provided metered pneumatic feeding and high-velocity injection of pulverized limestone into the high-temperature combustion zone of the BKZ-75-39F boiler, along with gas sampling and performance monitoring instrumentation.
