Method for generating heat energy and electrical energy from various types of waste and system for implementing said method

A method for generating thermal and electrical power from different wastes of the type comprising the use of a boiler to produce steam and feed said steam to a steam turbine that is connected to a generator:

• characterized in that it comprises:
• receiving sewage (AR) and various domestic and/or industrial wastes (RD) separately;
• purifying the sewage by separating solid wastes contained therein and processing the purified water to obtain treated water;
• obtaining hydrogen and oxygen from a portion of the treated water through an electrolysis process;
• obtaining biogas by a bio-digestion process of the organic fraction of the various wastes and from the solid wastes separated from the sewage;
• feeding a boiler:
• in a first step, with biogas and oxygen previously obtained from the wastes and the electrolysis process, until reaching a temperature of 600° C.;
• and in a second step, with treated water supplied at very high pressure to the boiler nozzles, retaining a minimum input of biogas, until reaching a temperature of 1200° C.
• producing superheated steam at a temperature above 650° C. and low humidity in a heat exchanger heated by the boiler;
• driving, by means of the steam produced, a steam turbine connected to an electric generator;
• condensing a certain volume of steam from the turbine and recirculating it to the heat exchanger to reuse it in a closed circuit, using the remaining steam from the turbine to raise the temperature of the water at the entrance of the electrolyser;
• and
• increasing the hydrogen production by processing the biogas that has not been necessary to input to the boiler for proper operation.
