    • Incineration plants for industrial waste

    Reliable heat, safe processes, high efficiency

    Numerous industries generate solid, liquid and / or paste-like residues and waste that can be used to generate energy. At the same time, landfill space – which is already in short supply due to environmental concerns – is becoming increasingly scarce, and legal requirements have long mandated the thermal / energy recovery of such materials. Modern incineration plants enable the safe and efficient thermal utilization of these material streams while simultaneously providing usable process heat. CAW develops robust and durable incineration plants designed for demanding industrial conditions – ranging from production waste to waste from forestry, wood-based materials production, and agriculture.

    How do industrial incineration plants work?

    Incineration plants utilize the energy content of waste or biomass to generate process heat, hot gases or other forms of thermal energy. Depending on the material, particle size, moisture content, ash content, and calorific value, different combustion principles are employed.

    Basic principle

    • The fuel is fed into a specially designed combustion chamber – as lump or bulk material, or in liquid or paste-like form.
    • Combustion takes place under defined and reproducible conditions with a controlled air supply, tailored to the type of fuel, combustion chamber temperature and power requirements.
    • The thermal energy released is recovered via specially designed heating surfaces and utilized in the form of thermal oil, warm and hot water, steam or hot gases.
    • Depending on the type and origin of the waste material and local emission requirements, combustion exhaust gases also pass through special afterburners and downstream exhaust gas treatment systems.
    • Combustion residues and ash are automatically discharged, collected in suitable containers and sent for proper disposal.

    Typical combustion systems

    • Mechanical moving grate firing in horizontal or inclined configurations: For heterogeneous, solid waste streams with varying calorific values, particle sizes, moisture and ash contents, typically forestry waste, all types of biomass, and biogenic production waste from the wood and wood-based materials industries.
    • Rotary kilns: For poorly combustible and highly heterogeneous residual materials or materials that require a long residence time for complete combustion.
    • Fluidised bed furnaces: For fine-grained, uniform fuels or material streams with a high mineral fraction.

    Technical features

    • Staged combustion for consistently low emissions and complete burnout.
    • High temperature stability thanks to robust combustion chamber / firebox lining.
    • Automated control of combustion air supply and exhaust gas recirculation.
    • Flexibility when fuel quality varies significantly.
    • Wide control range combined with high efficiency.

    Advantages of an industrial incineration plant

    Energy recovery from residual / waste materials

    Waste streams are no longer disposed of in landfills or burned uncontrollably outdoors / in open pits but are instead utilized in an environmentally friendly manner that reduces volume while simultaneously adding value.

    High operational reliability

    Robust and heavy-duty industrial construction designed for continuous operation and a long service life.

    Efficient heat supply

    Process heat across all temperature ranges and via any medium, such as thermal oil, warm and hot water, steam or hot gases.

    Reduced disposal costs

    Less external disposal due to direct resp. on-site thermal utilization.

    Automated ash removal

    Long operating cycles without interruptions.

    Low emissions

    Thanks to optimized combustion control, post-combustion / burnout chambers and exhaust gas cleaning.

    Flexible fuel selection

    Suitable for a wide range of waste and biomass qualities.

    High system availability

    Optimised for 24/7 industrial operation and high annual operating hours (> 8,400 hours/year verifiable).

    Industries and typical applications of incineration plants

    Incineration plants are suitable for companies that continuously generate combustible waste materials, commercially unusable biomass, or production residues. The energy generated can be used directly in production processes or converted into other forms of energy.

    Typical industries

    Wood and wood-based materials industry

    Agricultural and food industry

    Plastics, paper and packaging industry

    Recycling and waste management industry

    Chemical and manufacturing industry

    Building materials and cement industry

    Energy and power plant sector

    Typical applications

    • Incineration of all types of wood waste, such as bark, wet and dry veneer residues, sanding and sawdust, and wood chips contaminated with resin, binders, or varnishes.
    • Thermal utilization of agricultural waste such as peels, pomace, fruit pits, or green waste.
    • Utilization of production waste from the plastics, rubber, or textile manufacturing industries.
    • Co-incineration of hazardous waste or mixtures of residual materials from industrial processes.
    • Supply of thermal oil, warm and hot water, steam, or hot gases / hot air for production facilities.

    Suitable fuels and feedstocks

    All CAW incinerators are designed to handle a wide range of fuels. Both biogenic and industrial waste materials can be safely processed and thermally utilized.

    Solid fuels

    • Wood waste and woody biomass from the wood-processing industry e.g., sawmills, wood-based material production such as plywood, chipboard, MDF and OSB, thermal wood modification / ThermoWood® and forestry.
    • Residual materials from agricultural production, e.g. husks, kernels, straw, pomace.
    • Production waste from plastics, paper or textiles – depending on origin and composition.
    • Solid industrial waste with defined calorific values.

    Liquid and paste-like fuels

    • Organic residues from chemical processes
    • Liquid and paste-like by-products from the food or agricultural industries
    • Oil-containing production residues

    Thermal utilization of energy

    • Direct hot gas generation for drying and thermal processes
    • Thermal oil heating for high-temperature applications
    • Warm/hot water generation for building and district heating systems
    • Indirect steam generation for processes and combined heat and power generation (CHP)
    • Integration with ORC systems for decentralized power generation
