JONO’s MSW Solution

Efficient Waste Pre-Treatment in CFB Boilers

Project Overview

This project is dedicated to the mechanical pre-treatment of mixed municipal solid waste (MSW) before combustion in a circulating fluidized bed (CFB) boiler. Designed with a daily processing capacity of 1,000 tons, the system utilizes a two-stage shredding and mechanical separation process to efficiently classify and extract different waste components. The pre-treatment technology enables the separation of ferromagnetic metals, non-combustible materials such as glass, stones, and ash, as well as combustible fractions suitable for incineration.

Project Highlights

Advanced Crushing Technology

To get the best waste pre-treatment results, we adopted JONO's advanced crushing technology. The two-stage shredding system is key to breaking down combustible materials to about 80mm, making it easier to turn them into Solid Recovered Fuel (SRF). This high-quality SRF then goes straight into the CFB boiler for combustion.

Efficient Pre-treatment technology

The key technological processes involved in the project include:

Primary Shredding: The mixed MSW is initially shredded into manageable pieces, allowing for more effective separation and further processing.

Ferromagnetic Separation: Using magnetic separation technology, ferromagnetic metals are efficiently removed from the waste stream for recycling.

Secondary Shredding: The remaining waste undergoes a second shredding stage, ensuring that combustible materials are finely processed into SRF of approximately 80mm in size.

Non-Combustible Separation: Glass, stones, and ash are separated using mechanical sorting techniques, ensuring that only suitable materials enter the combustion process.

All the above pretreatment measures effectively improve the combustion state of the materials in the furnace, increase the complete combustion rate, and reduce the pressure on the subsequent exhaust gas treatment.

Conclusion

This mechanical pre-treatment project represents a significant advancement in the management of mixed municipal solid waste for energy recovery. By leveraging state-of-the-art shredding and separation technologies, the system efficiently processes waste, optimizes combustion, and contributes to environmental sustainability. The collaboration between Jano and Lindner ensures the successful implementation of cutting-edge waste processing technology, setting a benchmark for future waste-to-energy initiatives.
