Combined heat and power supply system and regional heat and power supply system

摘要

PROBLEM TO BE SOLVED: To provide an electrothermal cogeneration system capable of supplying heat medium and electric power to requirement, i.e. an electrothermal cogeneration system capable of simplifying facility configuration for transmitting heat medium and electric power to requirement.SOLUTION: An electrothermal cogeneration system capable of supplying heat medium and electric power to requirement comprises an electrothermal cogeneration device for increasing temperature of the heat medium and generating electric power and a heat medium flow passage connecting the electrothermal cogeneration device. The heat medium flow passage includes a heat medium pipe where the heat medium of which temperature is increased by the electrothermal cogeneration device, the heat medium pipe includes an electrical conductive part constituted by electrical conductive material and electric power generated by the electrothermal cogeneration device can be supplied to requirement through the electrical conductive part.SELECTED DRAWING: Figure 1
