The 25th National \"Safety Production Month\" in 2026: Everyone talks about safety, and everyone knows how to handle emergencies; identifying and addressing potential risks and hazards. -------------------------------------------------- Gasified fine slag is a solid waste generated in the coal gasification process, with its main components being the ash in the raw coal, some unconverted carbon, and any water present. With the rapid development of the modern coal chemical industry, the amount of gasification fine slag has increased significantly. Traditional disposal methods have many drawbacks: the moisture content of this fine slag is over 50%, and its open-air storage can lead to dust generation and leachate formation. The residual carbon contained in it also cannot be utilized effectively. In addition, there are issues such as excessive water consumption, high costs associated with transportation and wastewater treatment at slag disposal sites, and difficulties in proper disposal. The technical leader of the company’s project explained that industrial waste residues are \"resources\" in the wrong place. The project utilizes the company’s own developed technologies for \"deep dehydration and drying of gasified fine residues\" as well as a \"fluidized-suspended coupled self-stabilizing combustion technology for low-calorific-value solid wastes.\" First, the deep dehydration and drying process is used to reduce the moisture content of these fine residues from 85% to below 30%. Then, the residual carbon in these residues is used for self-stabilizing combustion (without the need for additional fuel coal) to produce industrial steam. In this way, the gasified fine residues can be disposed of safely and utilized as resources.
