ES-FR-AB

The plant for drying and combustion of biological and industrial sludges is based on a triple pass rotary drum.

The supplied plant system has a drying section and a combustion section.

The drying section has the following features:

• continuous automatic feeding system with screw conveyor;
• triple pass rotary drum with direct heating, equipped with fumes moisture condenser, dried sludge unloading, recycling screw feeders, exchangers for drying air pre-heating.

The combustion section has the following features:

• continuous automatic feeding system with screw conveyor;
• counter-current rotary kiln with controlled temperature (virtually a pyrolysis under sub-stoichiometric conditions) complete with burner and control board. Unloading of ashes is automatic and continuous;
• post combustion chamber is designed to grant: temperature of 850/1.050 °C, combustion gas residence time from > 2 seconds, swirl chamber to improve combustion’s efficiency, oxygen content > 6%;
• complete with burner, control board and emergency chimney;
• hot water pipes type heat exchanger for the production of superheated steam at  25 bar T = 450°C;
• flue gas cleaning system for the abatement of pollutants – acid fumes, dioxins and heavy metals – dry scrubbing type using bicarbonate and activated carbons. The system is supplied complete with reactor, reagent’s dosing and bag filter;
• PLC control unit complete with dedicated operating system and net connection for online assisted technical support;
• condensation steam turbine, complete with power supply generator, condenser, evaporation tower and accessories.

The proposed plant for drying and combustion of biological and industrial sludges is designed to meet the emission limits required and enforced by the EU Standard 2000/76/EU.
