Abstract |
A field prototype, alarm-level monitor for SO2 emissions from stationary sources was designed, fabricated and tested. The monitor was designed to be inexpensive, simple to operate and easily maintained. The monitoring system is an extractive type that employs an air aspirator to pull a sample through a probe and sample conditioning assembly. The gas sample flows through an analyzer that contains an electrochemical cell as the sensing element. The analyzer has the sensitivity to detect SO2 concentrations in a single range from 0 to 1000 parts per million. Visual and audible alarms are activated when SO2 emissions are in excess of a preset level. |
