Abstract: Thermal power plants have always been an important guarantee for the stable supply of electricity. This paper explores the design principles,equipment selection and engineering implementation methods of the automatic fire alarm system （FAS） for the coal storage and transportation system in thermal power plants. Taking the Antaibao low-calorific-value coal power generation project as an example,it conducts an in-depth discussion on the key points and difficulties in the design of the FAS architecture to ensure that the design scheme meets the requirements of norms and industry development,improve the fire prevention level of thermal power plants.

Key words: thermal power plant, automatic fire alarm system, fire safety, fire detectors
