The invention discloses a water vapor quality abnormity judgment method based on infrared spectroscopy and monitoring equipment. The water vapor quality abnormity judgment method is characterized by comprising the steps that: condensed water, feed water, superheated steam and reheated steam are sampled, hydrogen conductivity data and carbonate, formate and acetate data are obtained through a hydrogen conductivity meter and an infrared spectroscopy monitoring instrument respectively, the data are transmitted to a control analysis module, and the data analysis module longitudinally and transversely compares the hydrogen conductivity data, carbonate data, formate data and acetate data, that is, the water vapor detection concentrations and the theoretical concentrations are compared, and the water vapor quality abnormity reason is obtained. According to the water vapor quality abnormity judgment method, harmful ions (impurities) such as carbon dioxide and organic matters in the water vapor quality in the unit ope
