Acid Dewpoint Analyzer

Model：ADT-1200

Overview

When the coal is combusted, SO2 is formed and part of it is oxidized into SO3. After SO3 combines with the steam in the flue gas, the sulfur acid is formed. The condensation temperature of the sulfur acid in the flue gas is the acid dew point which is much higher than the water dew point. The higher the SO3 (or the sulfur acid steam) content, the higher the acid dew point temperature. 

The acid dewpoint detector helps the user understand the acid dewpoint temperature under certain working conditions. Thus, the user can adjust the exhaust gas temperature according to the acid dewpoint temperature to create the best condition for saving energy and expanding the furnace life.

Features

Based on the conductivity sensor technology, the acid dewpoint detector features its accurate, reliable and timely measurement as well as high repeatability. It can provide reliable control parameters for boiler safety and economic operation to achieve energy saving and low-temp corrosion prevention.

Applications

The acid dewpoint analyzer is used for measuring the acid dewpoint in the gas flue and providing reliable control data for boiler operation to prevent the flue wall and the equipment from low-temp corrosion. Its applications cover the coal-fired power, aluminum, steel, metallurgy, waste generation power station, cement and petrochemical plant.
