Heat-power decoupling and energy saving of the CHP unit with heat pump based waste heat recovery system

Haichao Wang et al.

Summary: This paper proposes using an electric heat pump to decouple heat and power and save energy, and analyzes the heat-power decoupling and energy saving potential. The results indicate that the heat-power decoupling potential is greater when the heat pump DH ratio and heat demand increase, and increasing the coefficient of performance and heat pump DH ratio can enhance the energy saving effect.

Innovative low-grade waste heat-based design of energy self-sufficient carbon-capture cogeneration system in coal-fired power plants

Tiancheng Ouyang et al.

Summary: This paper presents an innovative carbon capture system design based on low-grade waste heat to reduce costs and achieve energy self-sufficiency. The system utilizes waste heat from flue gas as an energy source to meet the power, cooling, and heat requirements of the carbon capture process. Economic analysis indicates that the system's initial investment can be recovered within 4.65 years.
