Drying RDF & SRF; From Bin Waste to High Calorific Fuel

Описание: Solid Recovered Fuel (SRF) is a well-sorted, highly refined waste stream comprising mainly of wood, card, paper, textiles and plastics. Unlike Refused Derived Fuel (RDF) which is used to generate energy for electricity and hot water, SRF has gone through additional processing to improve the overall quality and value. It has a higher calorific value than RDF and is commonly used in facilities such as waste to energy plants or cement kilns. Drying SRF and RDF, can, in the right circumstances, lead to significant financial and environmental benefits.

SRF varies in moisture depending on some factors; weather and season of course being the most significant. If the material is too wet, let’s say over 40% moisture, the cement works will not accept it and the waste to energy plant will apply a per ton penalty. It is vital to remove moisture in a Stronga SRF dryer to reach the specified moisture content and therefore calorific value determined by the fuel-receiving client.

Target moisture depends entirely on the client’s fuel specification. Waste to energy plants often have different pricing structures for high grade fuels so there will be a ‘sweet spot’ for the SRF producers / recycling companies. It is also important to remember that there are gates fees on the incoming material from local waste producers, local authorities etc. FlowDrya assists you to optimise the net price difference between incoming gates fee and cost to dispose via the SRF route (loose bulk or baled).

Clients investing in SRF drying systems from Stronga enjoy the control of consistently dry SRF and RDF material. Drying SRF using residual heat from CHP, for example, leads to level and stable SRF fuel moisture content and calorific value. Over time, the financial and environmental implications delivering the correct profile SRF fuel really add up.

Stronga SRF drying systems are highly efficient and financially viable when the client has a residual heat source ready. The objective of waste management facilities is to increase the calorific value of the SRF and thus to reduce the usage of CO² primary fuels. In addition to increasing calorific value, waste management facilities also benefit from:

• Reduced transport costs
• Reduced Energy from Waste (EfW) export costs
• Reduced landfill costs
• Improved processing productivity (e.g. fuel baling etc.)
• Meeting client’s fuel specification requirements while avoiding penalties
• Optimised operational income and profit
• Better control of your costs

Stronga SRF drying systems operate on a low temperature basis, ensuring safe and efficient low temperature drying of SRF material. Contact Stronga today to discuss the financial and environmental implications for your business, investing in SRF drying solutions.
