In a certain industrial park, there are 4 waste heat boilers used for coal-to-gas production; each boiler has a rated evaporation capacity of 21 t/h, with 15 t/h of steam being wasted. The steam pressure is 0.8 MPA and the temperature is 230 degrees. Previously, this steam was discharged directly, resulting in waste. Now, our company’s technology (Anhui Danning Environmental Protection Technology Co., Ltd.) is being used to reuse this waste heat, generating electricity through our turbines. Assuming 8,000 hours of operation per year, at a cost of around 0.65 yuan per kilowatt-hour, this can generate annual revenues of 40 million yuan. The economic benefits are substantial, and this technology can be applied to other medium- and low-pressure waste heat sources for reuse. (Saturated steam is also available.) Colleagues are welcome to ask questions.
