Sulphuric Acid Dewpoint Temperature Monitor   Need more information?  
Model 440 - Continuous Monitoring System

Benefits of Sulphuric Acid Dewpoint Monitoring
In order to maintain the operating efficiency of coal or oil-fired boilers, it is important to know that the temperature of the exhaust gas is above the sulphuric acid dewpoint temperature (ADT). If it is much higher than the sulphuric acid dewpoint temperature, then energy is wasted heating the gas and efficiency drops. Operating the boiler at temperatures below the sulphuric acid dewpoint temperature will result in the formation of sulphuric acid inside the boiler and particularly on the 'colder' parts of the plant.

Sulphuric Acid Dewpoint Temperature monitoring ensures that the optimum point is maintained - just above the sulphuric acid dewpoint - where no sulphuric acid is being formed, but efficiency is maximized.

Continuous sulphuric acid dewpoint temperature monitor
It is permanently installed in order to optimize combustion conditions by maintaining the temperature of the flue gas slightly above the sulphuric acid dewpoint temperature. It can continuously monitor the changes in boiler operation and provide a direct loop input to the boiler's own combustion control system.
