Patent ID: 8201408

Claim:
A sustainable closed loop system with zero waste for cogeneration of electric and thermal energy comprising an energy plantation of quick growing trees for providing a source of biomass, a biomass fuel preparation sub-system in close proximity to the energy plantation for drying and reducing the biomass into a fuel particles, a steam and power generation sub-system including a solid fuel burner for burning the fuel particles from the biomass fuel preparation sub-system and heating water in a boiler into steam, said burning of the fuel particles taking place in the solid fuel burner outside of the boiler, a turbine for converting the steam into mechanical energy, a generator for converting the mechanical energy into electrical energy, and a multi-effect distillation unit for producing distilled water from condensed steam from the turbine for recycle to the boiler whereby no chemicals are required for wastewater treatment, said biomass fuel preparation sub-system including a rotary dryer which is preheated with flue gas from the boiler.
