In order to solve the difficulty that beginner can not understand and grasp basic knowledge of thermal power plant in a short time, static demo, dynamic demo and test questions were done by using the construction design function of Authorware. The result shows that the frameworks design of Authorware have similarities to industrial process structure. After the software is run, equipments and its functions of thermal power plant can be displayed clearly from the static pictures and process of animation selective catalytic reduction denitrification can be exhibited vividly from dynamic scenes. Besides, test questions can help courseware learners to consolidate basic knowledge of thermal power plant. Moreover, selective catalytic reduction denitrification process of thermal power plant is regarded first as a sample to apply for teaching practice of power production.
