METHOD AND APPARATUS FOR MEASURING SO3 CONCENTRATION IN BURNED EXHAUST GAS

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for safely and inexpensively measuring SO3concentration in a burned exhaust gas. SOLUTION: The method of measuring SO3concentration in a burned exhaust gas is provided while including a step for obtaining a first measured solution by contacting the burned exhaust gas including SO3and water for a regular time, a step for obtaining a second measured solution by contacting the burned exhaust gas after contact and the first measured solution for a regular time, a step for measuring electrical conductivities of the first and second measured solutions, and a step for finding a difference between the electrical conductivities of the first and second measured solutions.
