Refuse-Derived Fuel & Solid Recovered Fuel System

RDF is a fuel made from MSW, industrial or commercial waste by shredding, screening, wind separating, iron removal, drying, addition of chemicals and compression. RDF fuel has a high calorific value, stable combustion, easy transportation, easy storage, low secondary pollution and low dioxin emissions

Solid Recovery Fuel(SRF) is a fuel made from non-hazardous waste according to European EN 15359 for use in incineration plants or co-incineration facilities for the purpose of energy recovery and reuse.

RDF/SRF fuels are currently used primarily for electricity and heating, but can also be used as an alternative fuel for cement plants. The use of RDF/SRF fuels helps to reduce reliance on limited fossil fuels while reducing carbon emissions to meet tightening global environmental requirements.

GEP ECOTECH is experienced in the field of RDF/SRF fuel preparation and can offer a comprehensive range of integrated disposal solutions. The equipment required for the system is stable and efficient, safe and reliable, with a low failure rate and low installed power, which significantly reduces system operating costs.

Refuse-Derived Fuel & Solid Recovered Fuel System

Universal solution

After pre-treatment such as bag-breaking and primary magnetic separation, the waste is removed from non-combustible materials such as metal, glass and sand, and the combustible materials in the waste (such as plastic, fibre, rubber, wood and food waste) are fed into the primary shredder, shredded into easily dryable pieces and then sent to the dryer via a conveyor. The moisture content is adjusted by controlling the hot air so that the material moisture is reduced to less than 8%. The dried flue gas is discharged through the dust remover and the dried material is sent to the wind separator after the second magnetic separation. The non-combustible material (ash, broken glass, metal shavings, etc.) is removed again and sent to the secondary shredder, where the material is shredded into small, easily formed particles, to which a certain amount of chemical is added, and then sent to the forming machine. The RDF is produced continuously by the forming machine, then cooled and sent through a vibrating screen into a hopper for the finished product, which is bagged by an automatic weighing machine, while the unqualified material is returned for re-forming.
