燃煤发电机组瞬态过程高效灵活清洁协同的能势动态匹配技术及应用

Coal fired power generation is gradually transitioning from a primary power source to a supporting and regulating source, frequently operating under transient processes such as peak and frequency regulation. Existing energy-saving and emission-reduction technologies primarily focus on steady-state conditions, making it difficult to effectively address the new demands of transient operation. This leads to three major technical challenges:high energy consumption during transient processes, insufficient load change rates, and excessive pollutant emissions during transient processes. Through the dynamic response time scale of thermal system transient processes and the rate of energy-quality transformation, this study establishes a new mechanism for energy potential matching that improves the transient performance of power units, extending energy-saving theories from steady-state conditions to transient processes. It develops a quantitative diagnostic method for transient energy consumption in Coal fired units is developed and invents a dynamic matching technology for energy potential through the collaborative control of wind, coal, and water flows in thermal energy storage states. In addition, it reveals the mechanism of rapidly converting thermal storage into work output to improve load change rates through material flow regulation, leading to the invention of an efficient, flexible, and synergistic energy-potential dynamic matching technology for orderly thermal storage utilization. Furthermore, a mechanism is established to achieve precise coupling between temperature fields and multi material concentration fields by feedforwarding the time-varying characteristics of heat exchanger thermal storage, and an energy-potential dynamic matching technology that synergistically regulates the temperature and flow of multiple media (including but not limited to flue gas, air, water) is invented, ensuring full compliance pollutant emissions across all operating conditions and deep waste heat recovery.
