A cogeneration and heat recovering system is provided to recover the heat of a cogeneration engine by 100 percents by allowing medium temperature water to heat-exchange with a heat exchanging section. A cogeneration and heat recovering system includes a recovering header(4), a supply header(5), a differential pressure valve(9), a middle temperature water pump(3), a three-way valve(6), a buffer(8), and a heat exchanging section(2). The middle temperature water passed through a rapid heating section and a heating section is recovered by the recovering header. The middle temperature water of a high temperature is supplied from the recovering header and a boiler to the supply header. The differential pressure valve is provided in a connection pipe between the supply header and the recovering header. The heat exchanging section is provided between the buffer and the recovering header to exchange heat with the middle temperature of a low temperature supplied from the buffer. |
