Alternative Fuel Preparation Technology in Cement Industry

RDF/SRF is now a Trend and Necessity in Cement Production

Based on analysis, producing one ton of cement typically requires around 3.4 GJ of energy. In 2023 alone, global cement production exceeded 4 billion tons. Historically sourced from coal, natural gas, or other fossil fuels, this has imposed significant environmental burdens. Today, employing RDF/SRF as alternative fuel is a popular choice, signifying both a commitment to environmental stewardship by cement companies and a substantial enhancement of market competitiveness.

Reduce Fuel Costs
A ton of coal typically costs below $150. However, most RDF fuels are priced at less than half the cost of coal. Additionally, the price per unit of heat from RDF is significantly lower than that of fossil fuels. Utilizing fossil fuels can substantially reduce energy costs for cement companies.
Minimize Pollution
Cement plants leverage raw materials destined for landfills as alternative fuels, significantly mitigating the risk of soil, groundwater, and air contamination from these wastes. This strategy also serves to extend the longevity of landfills.
Decrease Carbon Emissions
Using RDF/SRF as a fuel source emits fewer greenhouse gases compared to using fossil fuels, reducing the impact on the Earth's environment, while also helping companies save valuable carbon emission quotas.
Improve Cement Quality
The bottom ash remaining after the combustion of high-quality SRF fuel can be used as an additive component of cement clinker to reduce the consumption of raw materials. Additionally, materials containing metal components can improve the strength of cement.

Typical Sources of RDF/SRF

Municipal Solid Waste

The composition of municipal solid waste is relatively complex, including organic and non-degradable materials. After the recyclables are separated, dried, and shredded, the combustible components are used to make RDF/SRF.
Commercial & Industrial Waste

Commercial and industrial waste comes from industrial and commercial activities. It has simple ingredients and is the main source of high-quality SRF. The production process is also relatively simple.
Agricultural and Forestry Waste

Agricultural and forestry waste includes branches and leaves, straw, fruit shells, etc. Through appropriate treatment and conversion technologies, these biomass wastes can be converted into efficient, environmentally friendly biomass fuels for power generation, heating and other purposes.
Industrial Sludge

The organic components in the sludge not only increase the calorific value of the RDF but also aid in its shaping (if desired). These organic components can be combined with other combustible waste through proper processing and mixing to form solid fuels with greater combustion value and stability.

RDF/SRF Production Line Process Flow

The design of RDF/SRF production lines is usually adjusted according to the characteristics of different materials. This includes separating inert components, reducing humidity, and shredding the material to acceptable size (typically 5-10 cm) through one or more stages of equipment. If necessary, the chopped materials can also be made into granules. This design ensures the production of fuel that meets quality standards while maximizing production efficiency and resource utilization.

Municipal Solid Waste to RDF/SRF Processing System

MSW contains a large amount of recyclable and reusable raw materials, such as high calorific value combustibles that can be prepared into alternative fuels (RDF/SRF), organic matter that can be used for composting or fermentation in biogas digesters, and plastics, glass, metals, etc. that can be recycled and directly refurbished or processed as raw materials. The system includes a series of processes such as primary shredding, sorting, secondary shredding, and pelleting. The equipment used includes the double-shaft shredder, magnetic separator, trommel screen, wind sifter, fine shredder, dryer (for option according to the moisture content of the material), RDF pelleting mill, chain plate conveyor, belt conveyor, etc.

Waste Tire to Tire Derived Fuel (TDF) Processing System

Waste tires can generate as much energy as oil during combustion. The high calorific value of waste tires makes them an ideal alternative fuel for the cement industry. Based on the physical characteristics of waste tires, the extracted steel wire waste tires are sent to a specially designed double-shaft tire shredder for shredding, and the shredded tire chips can meet the incineration requirements of the cement plant.
