Coal-burning boiler online sulfur dioxide flue gas monitor Overview

The equipment installation location is between the primary desulfurization tower and the secondary desulfurization tower of the coal-fired boiler. There is a CEMS monitor at the entrance of the primary desulfurization tower. The concentration of SO2 is 2000mg/m3, up to 3000mg/m3. The purpose of monitoring the numerical size of sulfur dioxide at this position is Do not add desulfurization reactants in the secondary desulfurization and denitrification tower.
