11 Michaelis Energy from Waste Systems Feeding Incineration 11

12 Mobile Container Skid Modules: Transportable units Modular design No complicated buildings necessary Gravelling of place sufficient Low cost energy Steam or Hot water or Cooling energy or Thermal oil Desalinated water The system is designed and installed for very rigid conditions 12

13 Modular Waste-to-Energy System -Storage -Feeding -Moved bed incinerator -Second combustion chamber -Emergency stack -Deashing -Hot water boiler / chiller -Dry flue gas cleaning -Fan -Stack 13

14 Possible kinds of fuel: Unsorted municipal solid waste (MSW) Municipal sewage sludge (STP sludge) Biological wastes Manufacturing residuals Slaughterhouse wastes RDF material Hospital wastes (BMW) Hazardous wastes Oil sludge Shredded wood Others 14

15 Michaelis Modular Systems - Simple infrastructure - Modular systems - Rigid design 15

16 ENERGY RECOVERY Optimised Energy Utilisation by Cogeneration ~15-25 % Boiler Losses ~ 8-17% Electrical Output 100 % Fuel Energy ~ % Energy Utilization ~ % Heat Further Losses : 300 kg of industrial waste substitute about 1 MW primary energy => which equals approx. 100 L oil or about 100 m³ natural gas

17 ENERGY RECOVERY

18 Option: Steam Motor for Electrical Power Production 18

19 Michaelis Modular Systems Heat production: kwh/h Steam mass flow: 3 t/h or Hot water / cooling energy / thermal oil: kwh/h Possible Electrical power production: 400 to 500 kwh/h 19
