Substitute fuel or secondary fuel is fuel which normally consists of high-calorific waste The waste used for the production of substitute fuel may come from households, industry and trade.
Normally, industrial waste and bulky waste mainly contain
- Composite packagings
All these materials have a high calorific value. Using advanced treatment technology, a fuel (so-called co-incineration) is produced for the cement, lime and power station industry or even as a sole fuel in SF [substitute fuel] power plants.
After pre-crushing the material is screened, then separated by the wind sifter and followed by a separation of ferrous and non-ferrous metals with a subsequent NIR separation (near infrared separation). The material may be post-crushed again. Frequently, the material is pelletized until its use or can be filled into containers and/or stored in bunkers.
