According to the power generation device, the effects that the power generation efficiency is high, the power generation cost is low and the power generation limitation is small are achieved.

Description

technical field [0001] The invention relates to a power generation device, in particular to a low-temperature waste heat power generation device. Background technique [0002] Low-temperature waste heat refers to waste heat gas, condensed water, hot water generated in the process of production below 200°C, gas below 300°C, and exhaust gas from boilers and industrial heating furnaces below 400-450°C. Low-temperature waste heat Power generation refers to the technology of using these low-grade low-temperature waste heat to generate power. The methods are mainly low-grade thermal steam turbines, full-flow turbines, organic working medium Rankine cycle turbines, and screw expansion. Low-temperature waste heat power generation can not only recover a large amount of carbon dioxide, carbon monoxide and other toxic and harmful gases, reduce the greenhouse effect, but also greatly reduce the electricity consumption of production enterprises, effectively improving energy utilization e...
