Cogeneration system

摘要

A cogeneration system of the present invention includes: a power generation system (1) equipped with a power generator (11); waste heat utilization system (2) for recovering waste heat from the power generator (11), storing the heat, and utilize the waste heat as an effective output thermal energy; and a waste heat utilization promoting system for promoting utilization of the effective output thermal energy in the waste heat utilization system (12) to avoid a stop of the system associated with a heat storage amount reaching a full amount. A waste heat utilization promoting system (3) is equipped with a stop predicting function to predict an operation stop of the power generation system (1) by comparing a current operating state with a reference pattern and computing an operation sustainable time, and a stop warning function to give the user a warning of the operation stop with an image or sound according to stop prediction information obtained.
