JONO’s MSW Solution

Jinan Zhangqiu Waste Treatment Project

Project Overview

This project is located in Zhangqiu, Jinan, and focuses on the mechanical pre-treatment of mixed municipal solid waste (MSW) before incineration in a circulating fluidized bed (CFB) boiler. The system is designed with a daily processing capacity of 1,000 tons and utilizes a two-stage shredding and mechanical separation process to efficiently classify materials. This advanced pre-treatment technology enables the extraction of ferromagnetic metals, non-combustible materials such as glass, stones, and ash, as well as combustible components from the mixed MSW.

Project Highlights

Innovative Waste Treatment Approach

The project adopts an advanced waste treatment approach, integrating high-performance shredding and sorting technologies. To be specific, it includes two-stage shredding and mechanical separation.

Primary and Secondary Shredding:

The system uses a two-stage shredding process to reduce large waste materials to smaller, manageable sizes. The first stage performs initial size reduction, while the second stage refines the material to approximately 80mm.

Mechanical Separation:

- Ferromagnetic Metal Separation: Magnetic separators extract ferrous metals for recycling, reducing metal input into the incineration process.

- Non-Combustible Material Removal: Glass, stones, and ash are separated to prevent accumulation in the furnace, improving combustion efficiency.

- Combustible Material Sorting: Remaining waste, mainly paper, plastics, and organic residues, is classified as solid recovered fuel (SRF) for high-calorific-value incineration.

Advanced Equipment

JONO’s advanced shredding equipment like Aries Primary Shredder ensures that combustible waste is efficiently processed into SRF with a uniform particle size of approximately 80mm. This optimized fuel preparation significantly enhances combustion performance within the CFB boiler.

Economic Efficiency

By ensuring the particle size and quality of solid recovered fuel (SRF), this system optimizes the fuel combustion within the circulating fluidized bed (CFB) boiler, thereby significantly enhancing thermal efficiency and reducing energy loss, and improving economic benefits. Additionally, the pretreatment can reduce maintenance issues caused by the presence of unnecessary substances during incineration, thereby reducing downtime and operational costs.

Conclusion

This project represents a significant advancement in the pre-treatment of mixed municipal solid waste before incineration. By integrating robust shredding and sorting technologies, it enhances combustion efficiency, reduces environmental impact, and supports sustainable waste-to-energy conversion.
