Shredding Technology for Refuse Derived Fuels (RDF) - Energy - Energy - Waste to Energy
Refuse-derived fuel (RDF) is a fuel produced from various types of wastes such as Municipal Solid wastes (MSW), industrial wastes or commercial wastes. RDF consists largely of combustible components of such wastes, as non-recyclable plastics, paper cardboard, metal, and rubber. These fractions are separated by different processing steps, such as screening, air classification, ballistic separation, separation of ferrous and non-ferrous materials, glass, stones and other foreign materials and shredding into a uniform grain size. It can produce a homogenous material which can be used as substitute for fossil fuels, such as cement plants, lime plants, coal fired power plants. RDF can be also further specified into e.g. tire derived fuels (TDF) from, or solid recovered fuels (SRF).
RDF technology is widely used in cement plants, power plants, steam boilers and other industries to replace coal or natural gas. It saves much in energy and costs. It is essential for diverting waste from landfill.
Harden offers refuse derived fuels(RDF) shredding and recycling system. This production enable to process municipal solid waste to RDF. Substitute fuels/alternative fuels come from the high calorific value part of mix waste generated by city daily metabolism, mainly composed plastic, paper and wood chips. The most important influence for of RDF burning is content of the wet part (organic materials). Normally a mechanical or manual sorting is required for RDF production.
A RDF Production System mostly refers to the process flow as below:
1. Primary shredding.
A primary shredder (single shaft) can break bulk waste and packed waste.
2. Waste separating.
- ferrous separating by belt magnetic separator.
- hexagonal screen for size separating.
- Air separating for under-screen materials.
- The materials sorted and conveyed
3. Advanced shredding
4. Drying process
Our RDF Production eliminates around 50,000 tonnes of carbon dioxide equivalent gases from being emitted every year from the burning of fossil fuels. And every tonne of waste we divert from landfill eliminates 0.5 tonnes of carbon dioxide equivalent from being emitted in landfill gas.
