Sulfur and chlorine species in fuel will form sulfur dioxide, sulfur trioxide and hydrogen chloride within the combustion products. At low enough temperatures, these gases and the water vapor in the flue gas will condense to form _________ acid.

Question

Quizplus · Accepted Answer

The sulfur species will form sulfur dioxide and sulfur trioxide, which react with water vapor in the flue gas to form sulfuric acid. The chlorine species will form hydrogen chloride, which can also react with water to form hydrochloric acid. Therefore, both hydrochloric acid and sulfuric acid can form in the combustion products.
