## Abstract

An electricity-generating system of the invention which includes the following: a carbonization apparatus for carbonizing a carbonization source to form a carbonized product; a heat recovery steam generator for producing first steam through heat exchange with the heat exhausted from the carbonization apparatus; a carbonized fuel steam generator which employs the carbonized product serving as a fuel; a mixing header for mixing the first steam and a second steam produced by the carbonized fuel steam generator, which steams are fed thereinto, to thereby discharge a steam mixture having a uniform pressure; an electricity-generating apparatus for generating electricity by means of the steam mixture discharged from the mixing header as an actuating source; and an electricity-storing apparatus for storing the electricity generated by the electricity-generating apparatus.

## Claims

### Claim 1

An electricity-generating system comprising:
a carbonization apparatus for carbonizing a carbonization source to form a carbonized product;
a heat recovery steam generator for producing first steam through heat exchange with the heat exhausted from the carbonization apparatus;
a carbonized fuel steam generator which employs the carbonized product serving as a fuel;
a mixing header for mixing the first steam and second steam produced by the carbonized fuel steam generator, which steams are fed thereinto, to thereby discharge a steam mixture having a uniform pressure;
an electricity-generating apparatus for generating electricity by means of the steam mixture discharged from the mixing header as an actuating source; and
an electricity-storing apparatus for storing the electricity generated by the electricity-generating apparatus.

### Claim 2 (depends on 1)

An electricity-generating system according to claim 1, wherein the first steam is produced through heat exchange between water and the gas exhausted from the carbonization apparatus.

### Claim 3 (depends on 1)

An electricity-generating system according to claim 1, wherein the second steam is produced through heat exchange between water and the exhaust gas exhausted from the carbonized fuel steam generator.

### Claim 4 (depends on 1)

An electricity-generating system according to claim 1, wherein the mixing header has an internal space serving as a buffer chamber where the first steam and the second steam fed to the mixing header are temporarily stored.

### Claim 5 (depends on 1)

An electricity-generating system according to claim 1, wherein the electricity-generating apparatus generates electricity via a steam turbine.

### Claim 6 (depends on 1)

An electricity-generating system according to claim 1, wherein the carbonized fuel steam generator employs, as a raw material, the carbonized product produced by the carbonization apparatus.
