    • Incinerators for industrial waste

    reliable heat, safe processes, high efficiency

    Numerous industries produce solid, liquid and/or paste-like residues that can be used to generate energy. At the same time, landfill space, which is already critical from an environmental perspective, is becoming increasingly scarce, and legal requirements have long stipulated that these materials must be recycled for thermal/energy recovery. Modern incineration plants enable the safe and efficient thermal recovery of these material flows while also providing usable process heat. CAW develops robust and durable incineration plants that are designed for demanding industrial conditions – from production waste to waste from forestry, wood-based materials manufacturing and agriculture.

    How do industrial incinerators work?

    Incinerators use the energy content of waste or biomass to generate process heat, hot gases or other thermal energy. Different combustion principles are used depending on the material, piece sizes, water content, ash content and calorific value.

    Basic principle

    • The fuel is fed into a specially designed combustion chamber – as solid or bulk material, in liquid or paste 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 used in the form of thermal oil, 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 afterburn chambers and downstream exhaust gas purification systems.
    • Combustion residues and ash are automatically discharged, collected in suitable containers and sent for proper disposal.

    Typical combustion systems

    • Advance grate firing in flat or inclined design: For heterogeneous, solid waste streams with varying calorific values, particle sizes and moisture and ash contents, typically forestry waste, all types of biomass and biogenic production waste from the wood and wood-based materials industry.
    • Rotary kilns: For poorly combustible and highly inhomogeneous residues 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 lining.
    • Automated control of combustion air supply and exhaust gas recirculation.
    • Flexibility with highly variable fuel qualities.
    • Wide control range with high efficiency.

    Advantages of an industrial incineration plant

    Energy use of residual materials

    Waste streams are no longer disposed of in landfills or burned outdoors in an uncontrolled manner, but are used in an environmentally friendly and volume-reducing manner while also adding value.

    High operational reliability

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

    Efficient heat supply

    Process heat in all temperature ranges and using any media such as thermal oil, steam or hot gases.

    Reduced disposal costs

    Less external disposal through direct thermal recycling.

    Automated ash removal

    Long operating cycles without interruptions.

    Low emissions

    Through optimised combustion control, post-combustion and exhaust gas purification.

    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 areas of application for incinerators

    Incinerators are suitable for companies that continuously generate combustible waste materials, commercially unusable biomass or production waste. The energy generated can be used directly in production processes or transferred to other media.

    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 chips contaminated with glue/binders or varnish.
    • Thermal recycling of agricultural waste such as shells, pomace, fruit pits or green waste.
    • Use of production waste from plastics, rubber or textile manufacturing.
    • Co-incineration of hazardous waste or mixed residues from industrial processes.
    • Supply of thermal oil, warm/hot water, steam or hot gases 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 recycled.

    Solid fuels

    • Wood waste and biomass from the wood processing industry (sawmills, wood-based material production such as plywood, chipboard, MDF and OSB) 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 industry
    • Oil-containing production residues

    Thermal utilisation of energy

    • Direct hot gas generation for drying and thermal processes
    • Generation of thermal oil 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
    • Coupling with ORC systems for decentralised power generation.
