Abstract:This paper takes a single-stage industrial heating cogeneration unit as the research object,introduces a heat storage device into the system and combines it with the bypass system,and proposes a bypass-heat storage regulation that can adjust peaks in both the heat storage and heat release stages.This scheme can achieve continuous long-term peak regulation with less heat storage medium.This paper uses Ebsilon software to build the unit analysis model,and analyzes the original peak shaving scheme,the extraction steam heat storage peak shaving scheme,and the bypass-heat storage peak shaving scheme.The results show that the peak shaving range of the bypass-thermal storage peak regulation scheme is the largest,and the peak load reduction depth can reach 127.5 MW; the thermal efficiency of the bypass-thermal storage peak regulation scheme is the highest in one storage and discharge cycle,and the operation benefit is the largest.
