Baling petrochemical thermal power fly ash turning waste into treasure
The Baling Petrochemical Thermal Power Division has made full use of fly ash, a by-product of power generation, turning waste into valuable resources. Since its commissioning in 2000, the sales volume of fly ash has grown significantly, from an initial 2,000 tons to 210,000 tons in 2007. By the end of 2023, cumulative sales have reached 850,000 tons, contributing substantially to the company’s revenue and profitability.
However, the plant faced challenges due to poor coal quality, which made it difficult to collect fly ash efficiently. To address this, the department set a clear goal: "zero discharge" of ash and slag. This led to extensive technical upgrades of the equipment and adjustments to the boiler combustion conditions. Through continuous testing and timely fine-tuning of operational parameters, the boilers were kept in optimal working condition, ensuring stable and efficient performance.
At the same time, the department enhanced the inspection and maintenance of ash collection systems, preventing any loss of ash during the process. In March of last year, the division successfully produced secondary fly ash, with some of the products meeting national standards. These high-quality materials have attracted the attention of premium customers, further boosting market demand.
Last year alone, the sale of secondary fly ash generated nearly one million yuan in revenue, demonstrating the success of the company’s efforts in resource recovery and value creation. The initiative not only supports environmental sustainability but also strengthens the company’s competitive edge in the industry.
