Based on the original wet flue gas desulfurization system, the project innovatively adds a slurry flash evaporation system and an absorption heat pump system, constructing a closed-loop system of "waste heat recovery - energy conversion - resource reuse". Compared with traditional technologies, this technology has three prominent advantages: first, it achieves simultaneous energy and water conservation, reducing boiler coal consumption; second, it has high system compatibility, does not additionally increase the operating load of the induced draft fan, and ensures the stability of the main engine system; third, it has strong site adaptability and low construction difficulty. The project can recover approximately 300,000 GJ of waste heat annually, equivalent to saving about 10,230 tons of standard coal, reducing emissions of 27,200 tons of carbon dioxide, 87 tons of sulfur dioxide, and 75 tons of nitrogen oxides, and recovering about 110,000 tons of water resources per year. It provides an excellent replicable and promotable practical model for the energy-saving transformation of coal-fired power units.

The 350MW coal-fired unit wet flue gas desulfurization and flue gas waste heat recovery project of Zaozhuang Bayi Thermal Power Co., Ltd. is a key energy conservation and environmental protection project built by Guoshun Group in in-depth implementation of the spirit of the "Notice of the National Development and Reform Commission and the National Energy Administration on Carrying Out the Renovation and Upgrading of Coal-Fired Power Units Nationwide". The official commissioning of the project has changed the situation of insufficient utilization of waste heat and water resources, becoming a new model and benchmark for the coordinated and in-depth environmental governance of haze control, energy conservation, water conservation, pollution reduction, carbon reduction, and condensable particulate matter in winter in China. It plays a positive demonstration and leading role in promoting the clean and low-carbon transformation of the coal-fired power industry.

In the future, Guoshun Group will anchor the "dual carbon" strategic goal, adhere to taking scientific and technological innovation as the core engine, continue to deepen its cultivation in key fields such as clean energy utilization and environmental pollution control, provide customers with more energy-saving, environmentally friendly and efficient customized solutions, lead the industry to a new stage of green, environmentally friendly, efficient and flexible development, and write a new answer sheet for Beautiful China through green and low-carbon innovative practices!
