AI Technical Summary

Technical Problem

In existing technologies, the treatment of municipal solid waste and steel plant waste suffers from low resource utilization, serious pollution, and inconsistent treatment methods, making it difficult to achieve efficient energy utilization.

Method used

By sorting waste at the source and preparing waste-derived fuel, high-calorific-value, low-pollution waste-derived fuel is produced by mixing combustible waste fines, biogas residue, and sulfur and chlorine fixation agents, adjusting moisture content, and pressing into shape. This fuel is used for material drying in steel plants and for external engineering applications.

Benefits of technology

It has achieved efficient energy utilization of waste, reduced pollution emissions during incineration, improved resource utilization, and yielded significant economic and environmental benefits.

Abstract

This invention discloses a waste-derived fuel and a process for preparing it. The raw materials for the waste-derived fuel are as follows by mass percentage: 50%–80% combustible waste fines, 10%–30% biogas residue, and 5%–25% sulfur- and chlorine-fixing agents. This invention also provides processes for preparing waste-derived fuel from steel plant waste and from municipal solid waste and desulfurization ash. By classifying and treating waste at its source and using the combustible and organic components of the waste as raw materials for processing waste-derived fuel, this invention enables the resource utilization of municipal solid waste and steel plant waste, resulting in significant economic and environmental benefits.
