Refuse-Derived Fuel (RDF) is an environmentally friendly technology product developed as an alternative to environmentally harmful fuel types. It is a type of fuel that is frequently preferred by different sectors, especially cement factories. Within the scope of ASTM E711 (Standard Test Method for Gross Calorific Value of Refuse-Derived Fuel by Bomb Calorimeter) international standard, refuse-derived fuels can be produced in five different ways.
RDF 1: These are the fuels used in the form that large pieces of waste are thrown and removed.
RDF 2: Separation or not separation of ferrous metals from waste are fuels that are processed in the form of coarse particles.
RDF 3: These are fuels derived from crushed wastes separated from metal, glass and other inorganic materials.
RDF 4: These are fuels derived from combustible wastes converted into powder form.
RDF 5: These are fuels produced from condensed waste in the form of pellets, cubes or briquettes.
Additional to ASTM E711 Standard;
RDF 6: These are fuels converted from combustible wastes into liquid fuel. (ATY slurry)
RDF 7: These are fuels converted from combustible wastes into gaseous fuel. (ATY singaz)
The advantages of using Refuse-Derived Fuel are numerous, both economically and environmentally. The recycling of wastes that have lost their economic value but have energy value and using them as additional fuel helps to reduce energy costs in all factories, especially cement factories. In addition, it reduces the waste storage problem by reducing the amount of waste to be sent to the solid waste landfills of the municipalities. On the other hand, it provides an advantage in controlling the carbon footprint. The use of refuse-derived fuel as an energy source also contributes to the protection of natural resources.
For the operation of Refuse-Derived Fuel Facilities, there are requirements in the Communique on Refuse-Derived Fuel, Additional Fuel and Alternative Raw Materials prepared by the Ministry of Environment and Urbanization. In RDF preparation facilities, verification tests regarding the chemical content and physical properties of the wastes to be accepted must be carried out in the laboratories located in the facility. Availability of calorimeters in facility laboratories is among the conditions that RDF facilities must provide. The net calorific value of the wastes to be accepted to the facility should be known and should be prepared as fuel according to this value. Then, the caloric value of the prepared fuel should also be determined. The calorific value of the fuel to be prepared should be higher than 2500 cal/g. For this reason, it is important to carry out regular calorific value analyzes of the fuels to be prepared and prepared.
The characteristics of the fuel to be prepared should have the properties specified in the table below according to the Communique on Refuse-Derived Fuel, Additional Fuel and Alternative Raw Materials prepared by the Ministry of Environment and Urbanization.
RDF energy value can be determined with Calorimeter IC 210. Calorimeter IC 210, which has been manufactured and developed by Debye Technic, provides reliable results in terms of repeatability and accuracy of results in the analysis of samples with high and low caloric value. There is a special decomposition vessel option which is not affected by the chemical content of the sample. Thus, the combustion process required for Cl analysis can also be provided. Calorimeter IC 210 has Turkish or English language option for easy use by all operators.
