A waste heat power generation device having: an evaporator that recovers waste heat energy to evaporate a working medium; an expansion turbine generator that generates electric power with the working medium being supplied from the evaporator; a condenser that condenses the working medium discharged from the expansion turbine generator; a pump that feeds the working medium condensed in the condenser toward the evaporator; a measuring device that measures the amount of power generated by the expansion turbine generator per unit time; and a control device that controls the driving of the pump based on the measurement result of the measuring device.

Waste heat power generation device

A waste heat power generator (G, G) that includes an evaporator () to produce steam of a working medium, a power-generating device to generate electric power while expanding the steam, a condenser () to condense the steam which has passed through the power-generating device (), and a pump () to send the condensed working medium to the evaporator (). The waste heat power generator (G, G) may further include a valve device () to selectively supply a cooling medium used to cool the power-generating device () to the power-generating device (), and a controller () to control the valve device () based on the temperature of the power-generating device ().

Waste heat power generator

The waste heat power generator (G) includes: an evaporator () configured to produce steam of a working medium; a power-generating device () configured to generate electric power while expanding the steam; a condenser () configured to condense the steam which has passed through the power-generating device (); and a pump () configured to send the condensed working medium to the evaporator (). A bottom portion (BT) of the power-generating device () is provided with a discharge port () configured to discharge the working medium liquefied inside the power-generating device (), to the outside thereof. A discharge pipe () is provided in which one end thereof is connected to the discharge port () and the other end thereof is disposed in a channel for the working medium between the condenser () and the pump ().
