Abstract: In order to excavate the power generation potential of idle roof solar energy and waste heat of low temperature flue gas in the ceramic industrial park and use the low-price electricity for power storage and peak regulation, a new ceramic industry energy-saving system of multi-energy complementary was proposed, while its working performance and economic effect were systematically evaluated. With the introduction of the system into the ceramic industrial base, it is possible to save power consumption of 71.9569 million kW·h and power storage to regulate peak for 10.4690 million kW·h. As a result, the electricity cost is reduced by 64.4398 million yuan, while the return on investment is less than 4 years and the carbon emissions is decreased by 23,000 tons. The proposed system can be used to solve the problem of peak and valley imbalance of electricity consumption in the current ceramic industry, while reducing the energy consumption and carbon displacement in the production process. It is of important both theoretical and practical values for promoting the low-carbon green production in the ceramic industry.
