In this paper, the research progress of integrated solar chimney power plant system coupled with industrial waste flue gas, hot waste water, geothermal water and other heat sources is first introduced, from the perspective of coupling utilization of low-temperature heat source and solar chimney power generation technology. The use of low-temperature heat sources can greatly improve system performance, smooth the peak-to-valley difference of generated power and reduce the sensitivity of system performance to dynamic changes in the external environment, thus ensuring the stable and efficient operation of the system. In particular, the recycling of waste heat from industrial flue gas, wastewater and garbage greatly improves environmental thermal pollution. The integrated system coupled with low-temperature heat sources has positive significance for the commercial promotion of solar chimney power plant and the solution of environmental problems. In further exploration, attention should be paid, from the perspectives of system performance and its economy, to optimizing the layout design of the integrated system, scaling down the system and making it easier for multiple heat sources to deploy and complement each other.
